The History of the Guaraní

    In the fertile, wooded, eastern region of Paraguay lived numerous tribes of the Guarani-speaking Indians who inhabited much of the southeastern part of the continent. Semi-nomadic warriors, they had no wheel, plow, draft animals, or metals. They used bone, wood and thorns for tools and weapons. While living largely on fish and game, they also practiced a shifting agriculture, growing maize (avati) and mandioca (mandi'o) on different plots from one season to another. The Guaranis were a people of the forest and their word for Paradise or heaven was Yvága, which means "a place of abundant fruit trees." Their language, which was largely onomatopoeic in origin, still preserves the sounds of the forest. Their religious mythology allowed them to live in harmony with the prolific plant and animal life around them. It is said that they named 1,100 species of plants and knew their medicinal properties. Their prinicipal god was Tupang, or Tupâ, a pure, formless spirit which lived in and animated the whole universe. Tupâ was not capable of doing evil. Only one of the Guarani gods was evil. All the others were protectors of nature. Also, the actions of Tupang indicated that life on this earth was not final. Therefore, when the Christian missionaries came, the Guarani had little trouble in combining the two religions. The word Guarani means "warrior." Like modern Paraguayans, the Guaranis are friendly and hospitable, but fierce and stubborn in battle. Some Guarani tribes had fought the Guaycurus of the Chaco and pressed on to the edges of the Inca kingdom, coveting its riches long before the white man came.

Pombero - Man of the Night

    Pombero / Karai-pyharé / Man of the night

    Pombero is a anthropomorphic fairy, a man, ugly and short, hefty and dark, with hairy hands and feet, whose footsteps aren't heard. He is perhaps of Guaycuru origen. They also describe him as tattered, covered with a straw hat and a bag at his shoulder (confusion with Kari-Vosá). He lives in the forest or in abandoned places and houses, or in ghost-towns. He goes about at night, travelling all over. He has powers such as the abilities to mimic with ease, make himself invisible whenever he wants, making his presence known by touching them with his hairy hands, which produce pirî (goosebumps); he can glide over the longest distances, pass through a keyhole, run on all fours, imitate the songs of birds, especially the nocturnal birds, imitate the whistling of men, the sounds of snakes, the yells of animals, howls, the chirping of chicks, etc.
    nHe is also described as a ventriloquist. He is mischevious; he lets barn animals loose and disperses herds or packs of wild and domestic animals; he steals tabacco from the rack, scatters the gathered corn and the popî (peeled mandioc root), he steals honey, hens, and eggs. He throws riders from their horses, and scares the ride.
    He is sensual. He awakens women with the soft touch or caress of his hairy hands, especially those women who sleep outside in the summer nights. Sometimes he takes them; there are sometimes stories of women impregnated by Pombero, whose child is born looking very much like him. You also hear of young women kidnapped by Pombero, who after satisfying himself with them, let them loose, sometimes pregnant.
    In order to win his friendship or sympathy or his good will, you must give him gifts. People are accustomed to leaving him a bit of tabacco, honey, or other offerings, like a bottle of caña (alcohol from sugarcane ), etc., in an accesible place, in an attic, on top of some apyka (bench), in the okupe (back of the house), near the rancher's hut, uttering a short prayer, begging him not to commit more misdeeds. If his sympathy is won, Pombero takes care of the house of the person who left him gifts, and of his animals and possessions. They say the he even rewards his friends by placing fruits, eggs, and other things in the house.
    If you talk bad about Pombero, or don't leave him gifts, he can take revenge, persecuting the members of the house; he frightens those who talk bad about him, or through a simple touch, he leaves them mute (ñe'engu), crazy (tavy), or shaking (marachachâ). Our people [gram: Paraguayan people] take pains not to pronounce Pombero's name, especially at night gatherings. They refer to him as Karai-pyhare, "the man of the night," because he can appear whenever he is named, as if responding to a call.

    Ka'a He'e
    Officiele naam : Stevia Rebaudiana Bertoni
    Voorkomen : In wilde vorm in Sierras del Maracaju en in Amambay (Paraguay)
    Ontdekker : Moisés Santiago Bertoni, in 1887, de Paraguayse chemicus Dr. Ovidio Rebaudi heeft de zoetstof geïsoleerd (Steviósido).
    Chemische eigenschappen : Bevat Steviósido, Rebaudiósido A, en nog zes andere zoetmiddelen.
    Eigenschappen als zoetstof : Is 300 keer zoeter dan suiker ; om het gebruik te vergemakkelijken, komt het als poeder in een concentratie 1 op 300 in de handel (dus in een recept kan men een bepaalde hoeveelheid suiker direct door dezelfde hoeveelheid ka’a he’ê poeder vervangen).
    Medische eigenschappen :
    1. Verbetering van de circulatie in de pancreas, stimuleert de afzet van insuline, en kan - mits permanent ingenomen- de diabetici van de insulinespuiten enz. afhelpen. Reduceert het suikergehalte in het bloed. Voorgestelde dosis is 30 druppels waterig extract, 3 keer per dag.
    2. Vermageringsmiddel : het voortdurend gebruik van de bladeren van ka’a he’ê in infusies vermindert de opname van koolhidraten in het darmstelsel, en werkt daardoor als vermageringsmiddel.
    3. Hart- en bloedvaten : regulatie van de hartfuncties en versteviging van het bloedvaten-sisteem.
    4. Spijsvertering : is diuretisch en gaat zuurbranden tegen, elimineert via de urinewegen de giftstoffen in het lichaam.
    5. Reuma : behalve de regulering van het suikergehalte in het bloed, treedt er vermindering van reumatische pijnen op.
    6. Anti-cariës : vanwege het feit dat het produkt niet gist wordt het gebruikt in tandpastas en kauwgummi ; bestrijdt de bateries die cariës veroorzaken, het kauwen van bladeren - apart dat het de cariës tegenwerkt- is een zoeter vermaak dan gewone kauwgummi.
    7. Zenuwstelsel : gaat stress tegen, want is een relaxtiemiddel voor het zenuwstelstel ; goed voor personen die depressief zijn of aan bulimia lijden.
    8. Dermatologisch effect : heeft de capaciteit om huidcellen te regenereren ; heel effectief bij acne, huiduitslag, haarroos, eczeem, psoriasis en lepra ; ook effectief bij huidkanker.
    9. Anti-microbisch : effectief om de ontwikkeling van bacteries en andere infectie-organismen te controleren, gaat griep tegen en pakt mondbacteries aan, daarmee de cariës voorkomende.

    Toepassingen als zoetmiddel :
    1. Het extract wordt gebruikt bij de bereiding van totaal natuurlijke vruchtensappen (bijv. sinaasappelsap).
    2. Bereiding van koekjes en taarten, zelfs de gemalen bladeren worden gebruikt om consistentie aan deze producten te geven.
    3. Het waterige extract van ka’a he’ê neutraliseert het zuur van citrusfruiten, en biedt daarmee de mogelijkheid om daaruit gezonde en smakelijke dranken te bereiden.

    Verbouwing :
    In Paraguay, Brasilië, Japan, Korea, Taiwán, USA (Californië)
    Is sinds 1996 in de USA toegestaan door de FDA voor dietetische doelen.
    In Japan is het op dit moment al een populair zoetmiddel.

    Voordelen van Paraguay :
    De ka’a he’ê uit Paraguay is in zijn natuurlijke omgeving. De kwaliteit van de bladeren in Paraguay is beter dan in andere landen, en ze produceren meer kristallen dan ergens anders, vaak meer dan het dubbele. Daardoor is het rendiment van de bladeren beter bij eenzelfde kwaliteit oplosmiddel.

    Techniek van verbouwing :
    De plant vermenigvuldigt zich in de natuur op sexuele wijze, daardoor zijn er vele fenotipische verschillen, met uiteraard ook verschillen in het zoetstofgehalte. Actueel bestaan er al uitgelezen soorten, door selectieve kruising verkregen, met een hoog zoetstofgehalte.
    In Paraguay is men met de ontwikkeling van clones bezig (in reageerbuisjes) van uitgelezen planten. De productie van zaailingen gebeurt gewoonlijk met het gebruik van zaad of het uitplanten van scheuten (de gebruikelijke asexuele wijze).

    Sweet It Is! Life With Stevia: How
    Nutritional and Medicinal Uses
    Life with Stevia: How Sweet It Is! is not intended as medical advice. Its intention is solely educational. Please consult a medical or health professsional for medical advice.

    When one first observes the plant, nothing particular about it summons the attention, but when even a small piece of the leaf is placed in the mouth, one is amazed by its sweetness. A mere fragment of leaf is enough to sweeten the mouth for an hour.
    Those few simple words, issued in 1899, opened one of the more remarkable chapters in the history of botanical science, and introduced the world at large to a unique and potentially revolutionary plant from Paraguay known as stevia, or "honey leaf." In South America it is primarily known as yerba dulce, but among the Guarani Indians of Paraguay, who have used the plant for centuries, it has a variety of interesting names: Caa-ehe, Azuca-caa, Kaa-he-e and Ca-a-yupe; most of these names, in one way or another, draw attention to the sweet, nectar-like flavor of the leaf. Many Guarani medicinal and nutritional plactices incorporate stevia in one way or another. The remarkable Guarni possess one of the most advanced native cultures, in terms of philosophy, nutrition and medicine, of any similar group in the world. Yet their ways are still only vaguely understood by other people. A case in point is their use of stevia.
    Despite centuries of use by the Indians, it wasn't until 1899 that the plant was discovered by "civilized" man. M.S. Bertoni (quoted above) observed that the natives used the plant to sweeten their bitter drinks. Eventually, Bertoni was to be credited with the discovery of a new species; in his honor, stevia is now known as Stevia rebaudiana Bertoni.2-3
    It is amazing to contemplate that most of the important herbs and spices of the world have been known, described, catalogued and used by diverse populations for several centuries; yet here is one of the most wonderful plants of world that went undeteected until the turn of this century. Experts estimate that South America is the source of dozens, perhaps hundreds, of plants with properties as momentous as stevia that yet remain unused and unrecognized by anyone but the native populations. The Guarani are in possession of a good portion of these, some of which are becoming ever more important: yerba mate and lapacho. Others, like stevia, are less known.

    Stevia as a Flavor Enhancer
    There are three distinct traditions of stevia use. The first is for flavor enhancement; the second is as an herbal tea. The third is medicinal. The primary impetus for the development of stevia science was the discovery by Bertoni that the herb possessed an extraordinary sweetness. A good quality leaf is estimated to be 30 times sweeter than cane sugar, or sucrose.
    The active constituents of stevia are considered by the world's leading food scientists as the "sweeteners of the future." Therefore, every new development in the area of stevia research is anxiously awaited and thoroughly analyzed when it appears. Countries in which the currently used artificial sweetners are on the brink of being banned are desperately trying to find new, safe, non-caloric sweeteners. And in other countries, firms that hold exclusive rights to currently used sweeteners are extremely fearful of the advent of new, safer sweeteners, over which they will have no control. For these firms, the emergence of a totally natural, non-patentable sweetener is the ultimate horror. Stevia, whether these firms like it or not, will one day have a dramatic impact on all countries of the world. The necessary forces simply need to be properly aligned, the raging fury of mega-monstrous companies firmly bridled by caring governments, and the supply of stevia raised to meet the enormous demand.
    Steviosides and rebaudiosides are the principal constituents of diterpene glucosides with differing sugar molecules attached, as found in the leaves of the stevia plant. Extracted, they are currently being used as sweetening agents in several countries, including Japan, China, Korea, Taiwan, Israel, Uraguay, Brazil, and Paraguay. In Japan, commercialization of stevia was very rapid, beginning with the ban of artificial sweeteners during the 1960's. In 1970 the Japanese National Institute of Health began importing stevia for investigation, and by 1980 it was being used in hundreds of food products throughout the country.4
    This is remarkable progress, considering that as recently as 1921 scientists were just getting around to naming the main constituent (stevioside), and the molecule wasn't even accurately described until 1931, when scientists reported it to be a white, crystalline, hygroscopic powder, approximately 300 times sweeter than cane sugar.5 And it wasn't until 1955 that the earlier work was replicated and extended.6 By 1963, the complete chemical structures of the active molecules of stevia were finally worked out.7 To jump from there to the status of a major food sweetener by the mid-1970's was a truly astounding feat, one that would have simply been impossible in the United States or Europe. Today, the Japanese, who cultivate stevia extensively in their own country, are anxious that other countries adopt the use of the plant so that they might export it. The ironic thing is that the Japanese are not as encumbered with weight problems as the rest of us; they are not, therefore, adverse to using copious amounts of plain old sugar. Yet they have access, in the form of stevia, to one of the best sugar substitutes.
    While most of the attention focuses on the steviosides, research has shown that the rebaudiosides are actually much better tasting; there are just fewer of them. One rebaudioside in particular, Rebaudioside A, appears to be far superior. Its sweetening power is estimated to be 30% higher than that of stevioside. Efforts to genetically select for this constituent are underway in Japan. However, according to some sources, the plantations maintained by the Guarani in Paraguay contain perhaps the best tasting natural whole-leaf stevia available. Efforts to remove stevia from its native habitat and cultivate it in foreign soils may be primarily responsible for the off taste that characterizes non-Paraguayan stevia. The best stevia may indeed still be obtainable only from parts of Paraguay under native cultivation. Interestingly, a recent report showed that none of the stevia used in Japan is imported from Paraguay. Of the 1000 tons used in Japan in 1982, 300 were produced in Japan, 450 came from Continental China, 150 from Taiwan, 100 from Thailand and 50 from Korea, Brazil and Malaysia. It is said that the Paraguayans will not sell to Japan. Much, if not most, of the stevia sold in the U.S. is imported from China and other non-Paraguayan sources.
    "The sweetness of (stevia) satisfies my craving for sweets; also it helps keep the blood sugar balance."
    "When I'm drinking 2 or 3 cups of stevia tea a day, I don't experience my usual mood swings."
    Along these same lines, it may be that the use of whole leaf is an easier way to obtain better taste than through efforts aimed at trying to improve the taste of certain specific constituents. It is surprising, therefore, to see how much research has gone into attempting to improve the taste of individual steviosides or rebaudiosides. Since the white crystaline powder exhibits a quite persistent bitter and astringent aftertaste, cites use as a commercial sweetener often backfires. Thus, most manufacturers who use the isolated constituents of stevia usually have to combine it with other kinds of typical sugars! Since rebaudiosides taste better, methods are constantly being sought to synthetically convert steviosides to rebaudiosides. But even the rabaudiosides must be combined with other kinds of sugars to obtain necessary sweetness. Finally , in the ultimate irony, there are processes currently under development for improving the taste of stevioside by combining it in various ways with other substances obtained directly from stevia!8-9 It is the opinion of this author that most, if not all, of these convoluted attempts to improve the taste of single constituents could be satisfactorily avoided simply by using WHOLE LEAF, or whole leaf EXTRACT, the way nature intended stevia to be used. In the final analysis, pure stevioside is attractive to manufacturers mainly because of the higher profits to be achieved from using a purified, therefore patentable, material.


    In this country, where use of whole leaf is the only possible mode of administration, consumers have developed some rather sophisticated applications, especially in the medicinal area (see next section). In the area of combining with other foods, one can also find some useful aplications. Stevia is appropriate for use in conjunction with a variety of other herbal teas. One can mimic the South American practice of combining stevia with yerba mate, lapacho, and other native herbs, or one can experiment with stevia in altering the taste parameters of any number of traditional teas.
    "We are intrigued by the honeyleaf sweetener . . . and started to use it in our breadmaking to test it for our diabetic customers. We were so pleased with the results and the improvement in the texture and softness, that we have continued to use it on a regular basis in our bread and so have all of our customers, diabetic or not."
    Stevia is available in bulk, in tea bags, or as a liquid extract. Combine one tea bag of stevia with other herbal tea bags. Try straight stevia tea. Search for commercial products that contain stevia. You may find that some of these are too sweet for your taste. Others may be just right. If you purchase stevia in bulk, individual leaves and pieces of leaf can be added to beverages, sprinkled over salads or cooking vegetables and substituted for sugar in recipes without creating a problem due to the presence of the leaf itself. A little bit goes a long way.


    While there is no question that stevia is sweet, many users will admit that they have also experienced a bitter aftertaste from some brands. In fact, one of the problems with stevia products currently available from health food retailers is that many of them just plain do not taste good. They often have a distinct grassy taste, with varying degrees of bitterness associated with the sweet. These differences in quality may partly be a result of using non-Paraguayan stevia, partly due to poor extraction and processing techniques and partly the result of ignorance on the part of manufactureres concerning the real nature of the stevia plant. One knowledgeable producer of stevia products is attempting to set up industry standards for grading stevia leaves according to their quality. Grade A stevia would be the highest quality, an extremely sweet grade, with little bitter aftertaste and a concentrated degree of sweetness. This grade is very difficult to obtain due to climatic conditions that prevent harvesting at just the right time. Grade B would be a little less sweet with some minor deterioration of the leaf. Most of the best stevia arriving in the United States from Paraguay is Grade B. The vast majority of stevia sold in the United States would be classified as Grade C, a poor grade with a good deal of grassy, bitter flavor. Extracts of Grade C are particularly unpalatable, possessing far too much bitterness. Manufacturers often try to dress them up with other flavoring agents, but such attempts seldom work. Once you have tasted a premium stevia, you will never be satisfied by lesser products.
    The bitter principles are actually found in the veins of the leaf, while the leafy material between the veins contains the sweet components. Great care must be taken during production of stevia extract to avoid contaminating the sweet with the bitter. This pertains as much to extraction as it does to milling.
    Due to FDA regulations, pure stevioside or rebaudioside is not allowed in the United States. Even the leaf is suspect if it is labeled as a sweetener. Producers must exercise great caution in their labeling practices to avoid FDA involvement. Stevia and stevia extract are considered foods. Sweeteners are not foods, but food additives. Therefore, stevia cannot be called a sweetener. This, of course, restricts a manufacturer's ability to "get the word out" on stevia's use as a sweetening agent for teas or whatever. In practice, as long as the stevia industry poses no significant threat to the U.S. sugar or sugar substitute industries, the FDA will probably not be pressured to concern itself with what goes on with stevia labelling or use. Any perceived threat at all, however, could tip the scales the opposite way, and all forms of stevia could be banned.
    To keep things low-key, remember that the sweetening effect is simply a pleasant by-product. The primary reason that stevia is combined with the other herbs is to enhance the nutritive value of the other herbs! Stevia is, after all, nutrient-rich, containing substantial amounts of protein, calcium, phosphorous and other important nutrients.10-11


    Medicinal Uses
    Carrying the above thought a step further, there are many very ligitimate reasons for using stevia as a medicinal food. In spite of the prominence stevia has obtained as a flavor enhancer, it contains a variety of constituents besides the steviosides and rebaudiosides, including the nutrients specified above and a good deal of sterols, triterpenes, flavonoids, tannins, and an extremely rich volatile oil comprising rich proportions of aromatics, aldehyde, monoterpenes and sesquiterpenes.12 These and other, as yet unidentified constituents, probably have some impact on human physiology and may help explain some of the reported therapeutic uses of stevia.


    Hypoglycemic action.
    It is probably the presence of the steviosides themselves that has produced dozens of empirical and semi-controlled reports of hypoglycemic action. Paraguayans say that stevia is helpful for hypoglycemia and diabetes because it nourishes the pancreas and thereby helps to restore normal pancreatic function13 In semi-controlled clinical reports one also encounters this action. Oviedo, et. al., reported a 35.2% fall in normal blood sugar levels 6-8 hours following the ingestion of a stevia leaf extract.14 Similar trends have been reported in humans and experimental animals by other workers.15-16 These kind of results have led physicians in Paraguay to prescribe stevia leaf tea in the treatment of diabetes;13 similarly, in Brazil, stevia tea and stevia capsules are officiallly approved for sale for the treatment of diabetes.12
    However, it is important to note that stevia does not lower blood glucose levels in normal subjects. In one study, rats were fed crude extracts of stevia leaves for 56 days at a rate of 0.5 to 1.0 gram extract per day. These procedures were replicated by another team of scientists.17-18 Neither group observed a hypoglycemic action. Similar negative results have been obtained by other observers.19 Then there is research in which the findings show trends toward hypoglycemic action, but are inconclusive.20-21 In at least one of these studies, alloxan-diabetic rabbits were used. The authors felt the results supported an anti-diabetic action, but the results were transient at best.
    To date, the experimental research on the effects of stevia on blood sugar levels in human patients with either diabetes or hypoglycemia is sparse. The general feeling in the scientific community is that the mild acting nature of the plant and its total lack of toxic side effects argues against the need for extensive and expensive research programs.
    However, many of the anecdotes reporting a definite and significant blood sugar lowering action in diabetics, and a pronounced exhilarating effect in hypoglycemics, are sound enough to justify considerable experimental work in the area. Perhaps , when this missing piece to the puzzle is supplied, we will then have a better understanding of how stevia works - why, for example, many diabetic humans experience a profound lowering of blood sugar levels following the ingestion of several cups of stevia tea (24-32 oz.) during the course of a 24 hour period.


    Cardiovascular Action.
    A good deal of experimental work has been done on the effects of stevia and stevioside on cardiovascular functioning in man and animals. Some of this work was simply looking for possible toxicity, while some was investigating possible therapeutic astion. In neither case have significant properties been found. When any action at all is observed, it is almost always a slight lowering of arterial blood pressure at low and normal doses, changing to a slight rise in arterial pressure at very high doses.22 The most curious finding is a dose dependent action on heart beat, with a slight increase appearing at lower doses, changing to a mild decrease at higher doses. In neither instance is the result remarkable, and it is extremely doubtful that humans would experience any effect at normal doses.23 The long term use of stevia would probably have a cardiotonic action, that is, would produce a mild strengthening of the heart and vascular system.


    Antimicrobial Action
    The ability of stevia to inhibit the growth and reproduction of bacteria and other infectious organisms is important in at least two respects. First, it may help explain why users of stevia-enhanced products report a lower incidence of colds and flus, and second, it has fostered the invention of a number of mouthwash and tooth paste products. Research clearly shows that Streptococcus mutans, Pseudomonas aeruginos, Proteus vulgaris and other microbes do not thrive in the presence of the non-nutritive stevia constituents.24 This fact, combined with the naturally sweet flavor of the herb, makes it a suitable ingredient for mouth washes and for tooth pastes.25 The patent literature contains many applications for these kinds of stevia-based products. Stevia has even been shown to lower the incidence of dental caries.


    Digestive Tonic Action.
    In the literature of Brazil, stevia ranks high among the list of plants used for centuries by the "gauchos" of the southern plains to flavor the bitter medicinal preparations used by that nomadic culture. For example, it was widely used in their "mate." Through much experimentation, these people learned that stevia made a significant contribution to improved digestion, and that it improved overall gastrointestinal function.26 Likewise, since its introduction in China, stevia tea, made from either hot or cold water, is used as a low calorie, sweet-tasting tea, as an appetite stimulant, as a digestive aid, as an aid to weight management, and even for staying young.46


    Effects on the Skin.
    One of the properties of a liquid extract of stevia that has not yet been investigated experimentally is its apparent ability to help clear up skin problems. The Guarani and other people who have become familiar with stevia report that it is effective when applied to acne, seborrhea, dermatitis, eczema, etc. Placed directly in cuts and wounds, more rapid healing, without scarring, is observed. (This treatment may sting for a few seconds, but this is followed by a significant lowering of pain.) Smoother skin, softer to the touch is claimed to result from the frequent appllication of stevia poultices and extracts. Current FDA labelling regulations are forcing U.S. suppliers to label their stevia as something other than a sweetener; an appeal to its soothing action on the skin has been the most frequent alternative.


    Effects on Reproduction.
    An interesting pseudo-phenomenon arose at one time, and, sadly, still receives attention from time to time, in the popular press and even by serious scientists. It is sad because the whole thing is a hoax; if not that, it is at least a case of very badly mistaken identity. It seems that in 1968 a paper appeared that claimed that certain tribes of Indians in Paraguay (the Matto Grosso) used stevia tea as a contraceptive, with apparently very good results27 In subsequent experimental work, utilizing rats, these researchers found that the treatment was supposedly good for periods up to 2 months.
    Subsequent work has repeatedly failed to replicate the 1968 study.28-31 Furthermore, at least one attempt to locate tribes in northeastern Paraguay that used stevia to control fertility failed to confirm the story. One effect on reproductive physiology that appears to be valid, but which is in need of further study before definitive conclusions can be drawn, is a healing effect on the processes underlying prostate disease.32 Just how important this finding is must await further research.


    Safety Information
    One of the most obvious indications of the safety of stevia is that there have never been any reports of ill effects in over 1500 years of continuous use by Paraguayans. A similar indication of safety is the observaion that despite over ten years of widespread use of stevioside as a sweetening agent in Japan, years in which literally scores of tons of stevioside were ingested, not a single report of side effects of any kind has been reported. Compare that record to the track record of aspartame, which is the number one source of consumer food complaints made to the FDA.
    In spite of the record of safety, however the official laboratory tests must take place. The first official investigation of possible toxicity from stevia was performed in 1931 by Pomaret and coworkers in South America. Their tests were negative.33 They observed that stevioside passes through the human alimentary canal without being altered by digestive processes. That is, it goes out in exactly the same form that it goes in. In the decades since that observation there has raged a minor debate over this issue, but so far nobody has been able to prove Pomaret wrong. The issue is important because some of the metabolites of stevioside, as opposed to whole leaf, have been shown to be toxic (see below), and researchers have cautioned against the use of stevioside for human consumption until it is known for certain that stevioside is not metabolized in the human body. A typical statement is this from a report published in 1974:" . . . the long-term effects of ingestion of stevioside would have to be investigated carefully before it could be considered for human use as a sweetener in the United States . . . It remains to be proved that stevioside does not split to form any steviol in the human digestive tract." (italics theirs).34 This challenge is, of course, tantamount to proving a negative. Perhaps that is why the United States resists all efforts to seriously explore the possible use of stevia as a sweetener. No further progress on the issue has been made since 1974. It appears that Pomaret's observations still hold.
    More elaborate safety tests were performed by the Japanese during their evaluations of stevia as a possible sweetening agent. Few substances have ever yielded such consistently negative results in toxicity trials as has stevia. Almost every toxicity test imaginable has been performed on stevia extract or stevioside at one time or another The results are always negative. No abnormalities in weight change, food intake, cell or membrane characteristics, enzyme and substrate utilization, or chromosome characteristics. No cancer,no birth defects, no acute and no chronic untoward effects. Nothing.35-39
    The only related effect ever observed was the inhibition cell respiration (oxidative phosphorylation) in certain isolated cell components, but never in whole cells. The only observable result of this action, even after prolonged observation, was a reduction in toxicity due to a substance known as atractylignin, a poison that attacks cells of the liver. This result suggests that stevia could be used as an antidote to rare cases of poisoning by that chemical. The overall result of this action of stevia, then, turns out to be positive.40
    An example of a good toxicology trial was one performed in 1985 by Yamada and coworkers. They administered stevioside and rebaudioside A to rats for two years at the rate of 0.3 - 1% of their diet. The animals were then sacrificed, and the researchers conducted bio-chemical, anatomic, pathological and carcinogenic tests on 41 organs following autopsy. In addition they performed ongoing hematologic and urine tests on the same animals. Each of the animals was matched to a control animal that experienced exactly the same treatment except for the stevia. In the end, the symptoms and alterations noted by the research staff did not vary at all between the groups, and no dose-response effects were noted, even at the highest dose (1%), which is equivalent to 125 times the average daily dose of sweeteners that a normal human would require.41
    Similar batteries of tests carried out by the National Ministry of Health and Welfare in Japan also failed to find any form of toxicity whatsoever.42
    But there is a fly in the ointment, so to speak. As mentioned earlier, there has been a fear that metabolites of stevioside and rebaudioside A might be doing serious harm to the body. As one author put it: "In spite of the fact that acute oral administration of large doses of stevioside and/or Stevia rebaudiana extracts and long-term studies with feeding either of these materials to laboratory animals have shown them to be virtually devoid of toxic effects, one must consider the limited data available on metabolites (italics mine) of the major sweet principles of this plant."43 Now this comment was made in full knowledge of the fact that stevioside and the other glycosides of stevia are remarkable for their chemical stability; that is, due to their peculiar chemical or molecular shape, stevia glycosides are extremely resistant to acid and enzymatic degradation. They simply cannot be broken down into their metabolites under normal gastric conditions. Gastric acids and enzymes, as found in humans, are incapable of degrading these extremely stable molecules. This is in line with Pomaret's study that found that steviosides passed unchanged through the human gastrointestinal tract.
    Apparently the situation is different in the rat. In 1980 R.E. Wingard and associates reported that stevioside and rebaudioside A were both degraded to steviol by rat intestinal microflora in a test tube.44 Steviol is one of the nasty metabolites that could, maybe, perhaps, do humans serious harm. Wingard incubated the stevioside for 2-4 days in a specially prepared solution containing the contents of the rat cecum. Under these conditions, conversion was almost 100%. However, as Kinghorn and Soejarto have pointed out, there are just two things wrong with extrapolating these results to humans.45 First, humans do not have a cecum, as does the rat; therefore, a critical step in the conversion process has no equivalent physical location in which to occur. And second, there is no good reason to believe that the microflora of the human intestinal tract contains the same microorganisms as does the rat cecum.
    One would think, in light of the seriousness of the theoretical charge posed by Wingard, that scientists would be clamoring to settle the issue through appropriate experimental measures. Not so. It's as if no one really takes the threat seriously. After all, it is unlikely that some kind of observable consequence of steviol (the metabolite) intoxication would not have been reported during decades of stevia use if, in fact, a real problem existed. Since no reports have been forthcoming, we can daringly conclude (apparently along with the rest of the scientific community) that humans are different from rats.


    Conclusions from Safety Data.
    One might reasonably ask, based on these toxicological data, why efforts to make stevia the sugar substitute of choice in the United States and Europe have failed so miserably, and why, in fact, individuals who have attempted to produce high quality stevia liquid extracts in the United States have been threatened with prosecution. Here we have a plant, totally innocuous, posing no threat to human life and health, holding out in fact great hope for the production of a non-caloric sweetener with health benefits, that is being systematically suppressed.
    Perhaps, in view of the numerous health benefits discussed in this booklet (and the dozens of anecdotal uses not discussed, such as the ability to reduce the craving for sweets and fatty foods, and as a stop-smoking and/or stop drinking aide, the time has arrived for consumers to begin insisting on their right to freely use this fine, delectable plant from Paraguay. This author is certainly growing impatient with ongoing regulatory actions that appear to be deliberately designed to keep stevia out of his diet--a sad fate for a wonderful food like stevia.
    "The Symfre tea is the only natural decongestant that we have found that works. It's a good feeling to have a natural product that we can give to the whole family, including the baby, that clears congestion without drugs."


    From The Jungles To You
    Imagine that you live off the land in the lush tropical forests of South America, surrounded by an almost unimaginable array of trees, bushes, flowers, exposed to thousands of types of roots and berries and leaves. You are appointed medicine man (or woman) and your job is to keep yourself and the rest of the tribe healthy and to cure what ails them. What would you do? How would you go about devising techniques that work? Certainly you summon the help of whatever Gods and Spirits you believe in, and make the most out of whatever hype you could come up with. In that regard you would bear a close resemblance to the modern medical establishment. But then you would probably start looking for agents in nature that would serve your medicinal needs. Would you find anything? You bet you would. For the tropical forests of South America are the earth's richest storehouse of medicinal agents. You would probably jealously guard your secrets as you learned them, and eventually you might even try to make yourself into some kind of God. At some point you would select an heir to your knowledge, and over the centuries your knowledge would be enlarged upon by succeeding generations.
    "My son came home from college with the flu and had to go work that night. I got him on Symfre all day and he was fine (flu gone) by the time he went to work. Everyone else had it for 5 days."
    This hypothetical situation is a fairly accurate account of what could have happened to you, had you been a member of the Guarani Indian tribes of Paraguay. These people first came to the attention of Europeans sometime in the 1600's and were the subject of an intense missionary effort in the early 1700's. They were found to be a beautiful, ethical, highly skilled, very intelligent and gifted culture.
    Today, pure-blooded Guarani are declining in number, but much of their civilization has been preserved in one form or another. Thus it is that every once in a while, some one will be lucky enough to learn one or two of the secrets of the Guarani; even more rarely, such a lucky person will share it with the rest of us. As a result, we are just barely beginning to see some of the Guarani medical remedies reach the shores of North America.
    "I am having the best allergy season I ever had since I was seven years old back in 1938 !!! I've been in the hospital in oxygen tents more times than I can remember . . . I make 8 cups of Symfre and yerbamate mixed. And 5 cups of lapacho, I then mix 2 1/2 cups of lapacho with the yerbamate and Symfre and take a large bottle with me to work and sip it all day . . . . I have had no sign of any infection or bronchitis or asthma; and best of all I can get up in the morning and not sneeze 75 times before I get to work. I am thrilled!!!"
    One of the most promising of Guarani medicinal substances is, of course, stevia. It is known as "sweet leaf," or "honey leaf." This suggests the primary use of the plant in folklore use. Long before the country was colonized by the Spaniards in the sixteenth century, stevia was being employed to make food and drink palatable. Medicinally, the plant was used to treat diabetic and hypoglycemic conditions, and externally for keeping skin and hair youthful and healthy. Today, in homes and some clinics in rural Paraguay, stevia in high doses is given in tea form as a remedy for high blood sugar levels. The tonic, stomach-soothing, digestive, hypotensive and immune-stimulating actions of stevia are well known.
    It is interesting to see where stevia occurs in the traditional folk remedies of the native Guarani. Numerous are the folk medicines that contain stevia, either as a flavor enhancer or for its own medicinal properties. Most of these remedies are unknown beyond the edges of the fields and jungles.


    Natural Remedy for the Flu and Common Cold
    One example of a Guarani remedy (O'HO'MGUARA, meaning "It must go.") that has recently become available in the United States is a combination of stevia with a combination of two other plants: Piper dilatatum L. Rich, known colloquially as Yaguarundi, and Cecropia prachystachya Trecul, known as Amba-y. These latter two herbs have been re-designated in English as licorice pepper and Azteca, respectively. Very little is known about these plants beyond the edge of the villages. Yet it was one Peace Corps worker's good luck to be treated by this combination when he fell ill while working in Paraguay. Equally fortunate was the man's ability to persuade the Guarani indians to share the formula with him. But perhaps most important for those of us who use the comercial version of this compound, was the occasion upon which the Peace Corps worker shared his knowledge of O'HO'MGUARA with a friend in the United States. This herbal neophyte, at first highly skeptical of his friend's prepostrous claim that an obscure group of South American Indians had a cure for the common cold, was soon to become the world's leading advocate of this treatment. During subsequent trips to Paraguay, as he retells his experience, he personally witnessed the verification (in others and in himself!) of Indian claims that colds and flu could be cleared up in a day, and that sore throats could be cured in a matter of hours, as a result of the proper application of O'HO'MGUARA.
    Since that time, this American has shared the tea with thousands of others,, and has successfully brought the tea to the marketplace for all to enjoy. The difficult-to-pronounce Indian name was changed to the trade name Symfre, pronounced sym-free, as in sympton-free. Now, even some of the Paraguayan people refer to their native tea by that trade name.
    In Guarani lore, licorice pepper was used by itself for colds, flus, allergies, sore throat, coughs, and sinus congestion. Azteca was also used for the common cold, flu, coughs, allergies and sinus and lung congestion. It is also considered to be especially helpful for bronchial and pulmonary problems. Used together, the effect was said to be several orders of magnitude more dramatic and effective. Stevia was used to flavor the product and add stomach-soothing and digestive properties.
    "Having tried several of the herbal teas, to wit: lapacho, yerbamate and Symfre, I am very impressed! One of the most noticeable results has been . . . weight loss. Another has been fewer and less severe headaches. Also, some improvement regarding asthma, food allergies, and digestion . . . Generally, I've been feeling ever so much better, with vim and vigor. These herbal beverages. . . have been the best thing to come my way in years!"
    Another popular use for stevia in South America is to improve the taste of yerbamate. Many North Americans go to South America and become intrigued by mate only to be put off by the taste. Often they will resort to using large amounts of sugar in the tea to mask the flavor. Little do they realize that the ideal solution to the problem could be obtained simply by observing native practices. The addition of stevia to yerbamate markedly improves the taste for most of us. There are some people who seem to enjoy the natural flavor of mate, and feel the addition of sweetening agents of any kind makes the beverage too sweet. The majority of people, however, like it sweet. Stevia is the perfect answer to the question of how one sweetens the tea without adding calories and/or questionably safe artificial sweeteners.
    "Since I've been drinking this herbal tea (stevia and yerbamate), I have found energy I didn't know I had . . . I was sluggish, had headaches daily and basically was rundown . . . The tea has relieved all my problems, and most of all, I feel better knowing that it is completely natural, no harsh drugs or stimulants. I really enjoy the sweet taste with the benefit of no calories."
    These are just a couple of examples of the medicinal treasures hidden away in the lore of Paraguay and other South American countries.
    "I had a series of colds and sore throats. Very unusual for me. I ordered the yerba mate and Symfre and began drinking the tea. It broke up the infections, and I shared it several times with others, who also were relieved from cold symptoms."
    Slowly, these marvels are being uncovered and brought to the attention of the world.
    Let us hope that the day will soon come when simple, time-honored, health traditions with extraordinary potential for improving the lot of mankind, can be freely and openly offered to the world without interference from self-serving individuals, agencies, organizations and corporations which profit from the suppression of such fabulous, compelling and ultimately superior natural remedies.


    How to Use SYMFRE

  • A. For symptomatic relief of colds, flu, coughs, allergies, sinus congestion: Drink 8 cups (2 quarts) of tea in the course of one day, about 1 cup every 2-3 hours. Use 1 tablespoon per 8 oz. of water.
  • B. For relief of sore throat: Follow above directions but expect reslts in 4-5 hours.
  • C. For maintenance purposes: Drink tea made from 1 teaspoon per 8 oz. water, as desired.


    NOTE 1: For an even more dramatic and health promoting action, combine equal amounts of Symfre and yerbamate in 12-14 oz. hot water. Consume this every 3 hours throughout the day, with 1 or 2 cups the next morning.
    NOTE 2: Follow the native practice of combining Symfre with both yerbamate and lapacho. This is especially suggested in case of a deficiency in immune system functioning. "I have been using (a combination of yerbamate and stevia) for about two years. For 25 years, 365 days of each year, I had a sinus problem! Since I started using (the tea), the only time I have a problem is when I don't drink 3-4 eight ounce cups of tea each day. I am also a diabetic and I use about 10 drops of the (stevia extract) in each cup of tea. As long as I eat properly and exercise, I get a negative reading on my test. Two years ago my doctor wanted to put me on insulin, but now I no longer have to take any medication for my condition."

    Yerba Mate (Ilex paraquariensis)
    Unequaled Natural Nutrition


    Legends of the Guarani Indians
    The natural use of yerbamate' among the native Guarani is for healthful purposes. They use it to boost immunity, cleanse and detoxify the blood, tone the nervous system, restore youthful hair color, retard aging, combat fatigue, stimulate the mind, control the appetite, reduce the effects of debilitating disease, reduce stress, eliminate insomnia, and so forth
    We will explore the properties of yerbamate' in an effort to see if it qualifies for the accolades it has received down through the centuries..


    Description of Yerbamate'
    Mate' (Ilex paraquariensis) is an evergreen member of the holly family. It goes by several common names, including Paraguay tea, Jesuit tea, missionary tea and South American holly. It grows wild in Argentina, Chile, Peru, and Brazil, but is most abundant in Paraguay where it is also cultivated. The leaves are used nutritionally and medicinally; they are usually ground and steeped in hot water for several minutes and served hot or cold. The plant is classified according to Western herbal medicine as aromatic, stimulant, bitter, aperient, astringent, diuretic, purgative, sudorific, febrifuge, alterative and stimulant, but these terms sometimes miss the mark entirely, as we shall see.


    Constituents
    Several attempts to characterize part or all of the constituents of mate' have been made during the last few decades. They agree on some points, and disagree on others. This is not unusual; different assay techniques will be sensitive to different nutrients. The one thing that unites the various assays is the consistent detection of numerous vitamins and minerals. There is the usual array of resins, fiber, volatile oil, and tannins that characterize many plant substances. But then there is the growing list of vitamins and minerals, including carotene, vitamins A, C, E, B1, B2, B complex, riboflavin, nicotinic acid, pantothenic acid, biotin, vitamin C complex, magnesium, calcium, iron, sodium, potassium, manganese, silicon, phosphates, sulphur, hydrochloric acid, chlorophyll, choline, inositol. Different assays find different nutrients; there is probably no single assay that has found all of them. There are certainly still other nutrients that have not been identified as yet.
    One group of investigators from the Pasteur Institute and the Paris Scientific Society concluded that mate' contains practically all of the vitamins necessary to sustain life. They focused especially on pantothenic acid, remarking that it is rare to find a plant with so much of this significant and vital nutrient. It is indeed difficult to find a plant in any area of the world equal to mate' in nutritional value.
    In addition, mate' contains a substance belonging to a very specialized class of chemical compounds. Though only small amounts of this substance occur in mate', its presence has generated a huge amount of attention. The substance is a xanthine alkaloid called mateine. Because of all the attention heaped upon its presence in yerbamate', the following fairly extensive treatment is given, even though in reality the substance probably contributes little if anything to the activity of the plant.


    Yerbamate' and the Xanthine Alkaloids


    Does It Contain Any Caffeine?
    Gastrointestinal Properties
    Perhaps the main area of application of mate' is the gastrointestinal tract. Reported effects range from the immediate improvement in digestion to the ability to repair damaged and diseased gastrointestinal tissues.
    Constipation, acute or chronic, can easily be overcome through the use of mate'. Considering the seriousness of this health problem in the United States and other developed countries, a simple and effective solution such as drinking a pleasant beverage should be a welcome addition to treatment regimens. Mate' appears to work mainly by softening the fecal mass, but it also appears to stimulate normal peristalsis to some degree.
    "Before we became acquainted with Yerba mate', three out of the five members of our family suffered from constipation and hemorrhoids. Now that we have added mate' to our daily diet, not one of us suffers from either of these problems."
    Sometimes, hemorrhoidal relief can also be obtained through drinking the tea, since the bowel movement will reduce the pressure on blood vessels caused by the hard stool.
    Dieters use mate' to suppress the appetite, while providing necessary nutrition, energy and improved elimination to compensate for a reduction in ingested calories.


    Usage Recommendations
    One effective method is to drink 2-3 cups per day for 4-5 days. Another approach is to steep about two tablespoons 4-5 minutes in 16-32 ounces of water, and drink this daily, first thing in the morning on an empty stomach. Dieters drink one cup of tea 10-15 minutes before meals.
    "For several years I have had to take antacids because of a digestive problem. I have discovered that when I drink Yerba mate' daily, I do not have any need for medications. I feel so much better! I seem to have much more energy too."
    "I have recently discovered that...yerbamate' (3 cups a day) is absolutely remarkable in helping patients of mine lose weight quickly and safely... an average of 10 pounds in less than 3 weeks WITHOUT changing their normal diet or doing any extra exercise other than 20 minutes of walking every day. Other advantages...: reduction of allergies, firmer and smoother skin tone, increased energy levels and increased circulation..."
    "Yerbamate'...gives me energy and I am losing weight using it. It suppresses my appetite and even though the pollen count is in the severe level I am not sneezing. I love it!" Up


    Mate', Fatigue and the Nervous System
    Better than any other xanthine alkaloid, mate' has the ability to quicken the mind, increase mental alertness and acuity, and do it without any side effects such as nervousness and jitters. These observations have been made time and again by qualified medical experts as well as by the lay user.
    The effects of mate' on the nervous system are varied and not very well understood. The best guess is that it acts like a tonic, stimulating a weakened and depressed nervous system, and calming an overexcited one. Certainly the nutritional value of the plant cannot be overlooked as a possible substrate for improved health and function. Out knowledge of mate's effects are currently limited almost exclusively to observations on gross changes in behavior: such as an increase in energy and vitality, better ability to concentrate, less nervousness, agitation and anxiety, and increased resistance to both physical and mental fatigue.
    "Since I've been drinking (mate') tea, I have found energy I didn't know I had. I generally feel better...I was sluggish, had headaches daily and basically was rundown. I tried different vitamins but none of them seemed to work.The tea has relieved all of my problems and most of all I feel better knowing that it is completely natural, no harsh drugs or stimulants."
    "The (mate') tea does produce a feeling of general well being and is a reliable pick me up. It literally conquers fatigue! We love to drink it in the morning to start our day out refreshed without consuming unhealthy amounts of caffeine or sugar."
    One consistent observation is the improvement in mood, especially in depression, that follows the ingestion of the tea. This may be a direct result, or it may be an indirect result of increased energy.
    Reported improvements in memory have not been substantiated experimentally or clinically, but are logical, and may again be attributed to the nutrients, especially choline, an important central nervous system neuro-transmitter.
    One of the remarkable aspects of mate' is that it does not interfere with sleep cycles; in fact, it has a tendency to balance the cycles, inducing more REM sleep when necessary, or increasing the amount of time spent in delta states. Many people report that they require less sleep when using mate'; usually such an experience is accompanied by a deeper, more relaxing sleep.
    The non-addicting nature of mate' makes it an ideal substitute for people who are trying to kick the caffeine habit.

    Heart ailments of all kinds have been treated and/or prevented through yerbamate; use. Yerbamete' supplies many of the nutrients required by the heart for growth and repair. In addition, it increases the supply of oxygen to the heart, especially during periods of stress or exercise. This prevents the onset of lactic acid build-up and fatigue that occur when cellular oxygen levels fall below a critical point and low-energy producing, anaerobic glycolysis sets in.
    Reports of mate' reduing blood pressure are not uncommon.
    "I am 65 years old and have been suffering with blockage of the arteries. One of the arteries in my neck was closed 50% and the other one 45%. After drinking these teas for several weeks my doctor informed me that the arteries were both open and almost normal (and) that my heart is also now functioning almost normally (and) that I should discontinue the pills for circulation and the pills for the arteries."
    Mate also belongs to that class of herbal medicines called alteratives. That is, it seems to be continually striving to rid the blood of waste materials and miscellaneous toxins.


    Effects on the Immune System
    A consistent observation in most South American literature on mate' is that it increases the immune response capability of the body, stimulating the natural resistance to disease. This also involves a nourishing and strengthening effect on the ill person, both during the course of the illness and during convalescence, sometimes dramatically accelerating recovery times.
    Exact mechanisms of action have not been worked out, but they must certainly involve both a direct antimicrobial action against certain infectious organisms, and a general nonspecific effect on overall resistance. The nutritional content of the plant probably plays a major role here, but it is also probable that other constituents contribute to the action by stimulating the production and activity of white blood cells.
    "The thing we appreciate most about the mate' is that we have found that all of us are not sick as often as we used to be, and when we do catch a bug it is not as severe or long term as it was before... We believe this is due to the high nutrient content of the tea."


    Nutritional Properties
    As discussed in the section on constituents, mate' contains a wide variety of essential nutrients. The interactions and synergy among these nutrients have never been systematically studied. But the stories surrounding the nutritional applications of mate' tea are nothing short of amazing.
    Mate' is often used as a staple food, sometimes substituting for such important foods as bread and vegetables. It is easily capable of eliminating the sensation of hunger, and can impart a similar invigoration as a full meal. Peace Corps workers have reported cases in which large groups of natives remain in good health for extended periods of drought and famine, even though they eat only one small meal per day. How so? By drinking copious amounts of yerbamate' tea. Some natives spend their entire lives on such a diet, and live to very advanced ages, sometimes in excess of 100 years.
    South American governments have adopted the practice of encouraging mothers, especially in the poorer regions, to include yerbamate' in the diet of their school age children.
    "...I began drinking yerbamate' after about a three year illness. At the time I was at a point of pretty good recovery, but was having so much trouble with tenseness, sleeping or even resting. I...began taking four to six cups a day. I was overjoyed when within 24 to 48 hours, I was able to lay down and actually rest and drop off to sleep. Much to my surprise, within about three weeks my hair...started to perk up, gain body and return to normal."
    North American and European missionaries sent to the river forests of Paraguay and Brazil routinely report periods where they themselves have gone for months at a time subsisting only on yerbamate' tea with no observable ill effects other than some weight loss.
    Sailors routinely use mate' to prevent scurvy, but that alone doesn't signify a great deal. Much more interesting are reports of mate's ability to increase the sailors' ability to adapt to the hot, humid, stultifying environments of furnace rooms, galleys, boiler rooms, etc. In fact, this is an extraordinary attribute of mate' in general. One of the best ways to adapt to the jungle climate of South America is the frequent drinking of mate' tea.
    There is the story of a telegram sent during the Russo-Japanese war that stated that the only Japanese regiments that did not suffer from foot infections, apparently caused by rice consumption (?), were those that drank mate' tea instead of the normally and widely ingested tea or coffee. Similar nutritional benefits have been reported by the medical researchers in the Italian army who observed the rejuvenating effects of mate' among undernourished and diseased soldiers in infantry regiments.
    An article in "The Society Arts Journal" noted, "Mate' has an amazing power to sustain strength neither tea nor chocolate can pretend to have. Hikers using mate' are able to walk six to seven hours without the necessity of eating."
    We might also point out that the nutrients in mate' tea are in a liquefied state and are therefore more easily assimilated than the nutrients in other foods or in pills or capsules.


    Endocrine/Metabolic Properties
    Mate' has long been known to prevent and reduce fatigue. The most logical mechanism of action at this time seems to be a direct stimulating effect on metabolism in muscle cells.
    Additionally, there is growing clinical evidence that mate' stimulates the adrenal glands to produce corticosteroids. This mechanism of action may account for the commonly observed action of mate' to decrease the severity and incidence of allergy and hay fever.


    Usage Recommendations
    The recommended application for allergy relief is three or more tablespoons of bulk (pulverized) herb, steeped 5-10 minutes in 24 or more oz. of water.This would be sipped through a bombilla first thing in the morning on an empty stomach, or whenever symptoms arise.
    "While I was given the herbal beverage to relieve fatigue . . . it also completely eliminated all of my allergy symptoms. . . I experimented for several days. It worked every time!"
    "I have been using yerbamate' for about two years. For 25 years, 365 days of each year, I had a sinus problem! Since I started using yerbamate' . . ., the only time I have a problem is when I don't drink 3-4 eight ounce cups of tea each day. Yerbamate' . . . has truly changed my life. I am seldom sick, always feel good and have a lot of energy."
    (After discussing a long history of allergy complications in her son) "We didn't want to get him started on medication again, so we prayed for wisdom. While visiting friends a week later, we were introduced to yerbamate' tea. I, too, was having some allergy problems, but, almost instantly after drinking one cup of tea, my nasal passages dried up. In a week's time (our son) was all dried up and feeling so much better. We gave him one or two cups each day. Now, two months later, the tea continues to be effective treatment."
    The adrenocortical action may help explain reported cases of hypoglycemic patients responding to mate'. It is possible that mate', by stimulating the adrenal cortex to secrete glucocorticoids, helps balance blood glucose levels. Similarly, it may also stimulate the production of mineralcorticoids, thereby helping to regulate electrolyte metabolism. These hypotheses are attractive, given certain clinical observations, but need to be scrutinized more closely in experimental settings.
    "I have a very sluggish body. I am hypoglycemic/borderline diabetic and I have swollen gums and infected jawbones. My digestive system leaves a lot to be desired. I have trouble digesting proteins, starches and sugars. Upon drinking yerbamate' and purple lapacho, I found myself running around and feeling like I was 17 years old (she is 50). My mind and body were all of a sudden pulled out of a sluggishness into top performance."
    Mate reduces the effects of stress on the body; this property probably involves a combination of effects on the endocrine system, the nervous system and the immune system, but is one of the most important of the herb's actions.


    Miscellaneous Uses


  • 1. Alcohol Substitute. One finds frequent reference to this property of mate' in South American literature on herbal medicine. Apparently, alcoholics find the ingestion of yerbamate' a pleasant substitute for liquor. The detoxification action of mate' must certainly play a role here. The rapid regeneration of liver tissue and the observable increase in vigor, clarity of thought and health must all be involved in the effectiveness of mate' for this condition.
  • 2. Degenerative Conditions. Related to its amazing nutritive value are the frequent applications of mate' to overcome the debilitating effects of neurasthenia, rheumatism, diabetes and senility. The special constellation of nutritive effects of mate' can sometimes be seen in a reduction or reversal of some signs of aging, including wrinkles, amount of time spent in convalescence and mood swings.
  • 3. Headaches, Migraine and Neuralgia. The combined effects of mate' on the nervous and cardiovascular system probably helps to account for its ability to relieve various kinds of pain in the area of the skull.
  • 4. Diuretic. There is no doubt that mate' can induce diuresis. But the effect seems to be tonic in nature, i.e., it only kicks in when you need it. This is good, because we wouldn't want to have our bodies continually trying to divest itself of intracellular water.
  • 5. Hair Color. It is felt by some mate' aficionados that use of the herb helps maintain a youthful hair color. Admittedly far out, this claim may nevertheless contain a rudiment of validity to the degree that proper nutrition or the proper mix of nutrients might contribute to such a phenomenon.
  • 6. Sexual Performance. Improvements in this rather subjective domain have been reported. Just how valid such reports are, even if truly believed by the participants, cannot be determined without considerable clinical research. Should mate' be proved to have stimulating effect on the adrenal glands (which appears very likely), one could expect some effect on the production and regulation of androgenic hormones, with a resulting effect of some kind on sexuality.


    Quallity
    We are just entering an era of increased trade with South America, and the importation of herbal materials is still very primitive. Problems of communication, of being able to oversee operations, of simple plant identification and other problems make trade in South American herbs a difficult practice. In addition, South American herbalists are the first to admit the impurity of almost all yerbamate' products currently found on the market. They are full of insect parts, materials from other plants with irritating effects on the gastrointestinal tract, and they are sometimes totally misidentified.
    One common problem in the mate' market is a general lack of awareness concerning the importance of allowing the plant to dry or 'cure' for several months (at least twelve) before packaging it for sale. In a general survey I recently made of about half a dozen importers, only one considered this an aspect worthy of consideration.
    For these and other reasons, it is wise to purchase your mate' only from a reputable firm that takes extraordinary means to overcome the inherent difficulties. You may find it difficult to locate that firm, but the search is worth the trouble.
    Generally, a firm that specializes in yerbamate' (and other South American herbs) will be best informed and much more careful in their importing practices from that continent.


    Yerbamate' and Stevia
    Some people find the taste of pure yerbamate' somewhat unpleasant, kind of like alfalfa. For this reason the practice of combining mate' with the very pleasant tasting stevia, another herb from South America, has become a very popular way of enhancing the flavor. It indeed makes for a regal treat.
    Stevia is a very healthful herb in its own right, being widely used both internally for stomach ailments and blood sugar regulation, and externally for skin problems, such as acne, cuts, bruises and burns.


    The Bombilla
    The Argentines and Paraguayans developed a method for ingesting yerba mate' that, in concept, deserves to be emulated by other
    nations. The method uses a straw, usually metal, that has a fine metal filter attached to the end which is inserted in the tea. The straw replaces the tea bag as a means for keeping fibrous material from being mixed with the ingested liquid tea.
    The bombilla has the advantage that it can be inserted directly into the bulk of leaves and twigs (twigs must be removed from material put in a tea bag). As one sucks on the straw embedded in the mass of herb, the herbal material becomes lodged against the screen and the liquid is drawn through it. This process forcibly removes far more of the nutrients from the herb than any other practical method. Some of the finer particulate matter works its way through the holes in the strainer and is ingested, but this material causes no discomfort whatsoever, and is good for you. The better bombillas can be placed in a dishwasher for cleaning.
    The bombilla method was probably developed by the natives as experience taught them that they received a good deal more nutritional value by using this method of extraction.
    The bombilla method has received some criticism from an hygienic point of view. Indeed, when used in the mate' rituals of South America, where the straw is passed from one participant to another around the circle, it probably is an unsanitary practice. But a one owner-one bombilla concept has much to recommend itself in terms of both hygiene and nutrition.
