Guest guest Posted December 22, 2004 Report Share Posted December 22, 2004 MIT scientists promote FDA agenda to regulate herbs Two scientists at MIT, Shiladitya Sengupta and Ram Sasisekharan, have discovered that there are chemical constituents of ginseng that have opposing effects on blood vessel growth. One isolated constituent promoted blood vessel growth, which is beneficial wound healing, but which they suggest may be problematic in cases of cancer. Another isolated constituent inhibited blood vessel growth - an antiangiogenesis factor that might be useful in cases of cancer. Moreover, the relative ratios of these two constituents varied, depending upon the preparation methods used to process the ginseng before sale. They admit that the problem is more complex, as the action of each of these compounds may be modulated by the presence of sugar groups attached as side chains to these molecules, and the specific modulatory effect depends upon the location of attachment. Based on these discoveries, the two MIT researchers have concluded that the FDA should regulate ginseng as a drug, because many herb businesses are selling ginseng to the public with various health claims. Moreover, they have developed what they claim is a rigorous method for standardizing herbal supplements and intend to convince the FDA to mandate their process as a means of quality control in the manufacturing of herbal supplements. Commentary: While Sengupta and Sasisekharan should be congratulated for their discoveries regarding ginseng, their conclusion that ginseng should be regulated by the FDA requires a gigantic leap of logic that goes far beyond considerations of biochemistry. Traditional Chinese herbalists have long recognized that ginseng is indicated in a wide range of debilitated conditions, as long a specific criteria are met - a significant number of the following symptoms must be present: fatigue; dehydration; weak pulse; pale complexion and tongue; withdrawn, quiet behavior; poor resistance to infections; low stamina and stress tolerance. Moreover, ginseng is specifically contraindicated in such conditions as high blood pressure, irritability and agitation, and abdominal bloating. Ginseng is classified as an adaptogenic herb by most herbalists. Adaptogens typically have complex chemical constituents with multiple effects, many of them regulatory in nature or of a dual nature. The effects on blood vessel growth that Sengupta and Sasikharan have discovered is typical of such a dual effect. Adaptogens may often manifest paradoxical effects in different individuals - for example, lowering blood sugar in individuals with high levels, but increasing levels if they are too low. Attachment of sugar side chains to complex biomolecules is a common means for the body to alter their cell wall permeability. A chemical without such a side chain may not be able to penetrate the cell wall, but with the sugar group attached, it may pass through easily. Without the ability to penetrate cell walls, many chemicals will show much reduced physiologic activity. The human body is capable to a great degree of accepting, rejecting, or altering the chemical constituents of foods and herbs for its own needs. Alteration, breakdown, and reconstitution of ingested molecules are routine aspects of digestive and cellular metabolism. To suggest that merely because the effects of ginseng are variable with respect to blood vessel growth, it must be regulated by the FDA is a non sequitur unworthy of scientists supposedly guided by logic and reason. Let's examine this chain of logic to see where it leads. According to an article in Biochemistry (Moscow), " The dietary constituents selenium, N-acetylcysteine, vitamin D3, curcumin, flavonoids, and several fatty acids (i.e., eicosapentaenoic acid) have all been shown to inhibit angiogenesis in vitro and/or in vivo. " These constituents are found in a wide range of common foods - vegetables, spices (turmeric), fish oils, flax seed, etc. Copper, arginine, and glycine are pro-angiogenic dietary constituents and play an important role in normal tissue repair. Simply because something has an anti-angiogenic effect does not mean that it will be healthy - thalidomide is a potent anti-angiogenic drug, and it had truly horrible effects on developing fetuses. The body requires angiogenic factors to promote normal tissue growth and repair, yet anti-angiogenic factors are also beneficial in the diet to keep this necessary process under control. For almost every biochemical process in the body, there are complementary or opposing processes that regulate it and keep it in balance. In summary, the mere fact that two MIT scientists have discovered both anti-angiogenesism and pro-angiogenesis factors in ginseng is no earth-shattering discovery. Such compounds have been found in a wide variety of foods. This should not be surprising; foods are foods because they contain the fuel and building blocks of life. If ginseng is such a danger to the public that it needs to be regulated, then fish, wine, vegetables, flax seed, liver, and shellfish are equally dangerous. Must we have corrupt FDA officials invade our food shops and kitchens too? The FDA has a hypocritical double standard with respect to safety. Deaths from prescription medications barely merit an eye blink in the media, even though non-error, adverse effects of medications are the fourth leading cause of death (106,000 deaths/year). Yet a single death or negative effect from an herbal product often results in shrill demands by the FDA for increased regulation. In summary, I suggest that researchers Sengupta and Sasisekharan stick to herbal research and refrain from comments on herbal politics and regulation until they have properly informed themselves on how the American system of drug and food regulation really works. For starters, how about reading the following? http://www.rmhiherbal.org/review/2003-2.html Orwellian schemes for maximizing health-care industry profits - How these endanger the practice of herbal medicine Note especially the section in the preceding article on the various types of official mischief that can result from mandatory biochemical standardization of herbal products, in contrast to voluntary certification, which may help to increase herbal product quality: http://www.rmhiherbal.org/review/2003-2.html#t-bioc Promote adoption of regulatory standardization of biochemical profiles for herbal products. Sengupta and Sasisekharan may hope to patent their method, and their profits may be huge if the FDA mandates their scheme to regulate herbal products. The public should be aware of the biases in scientific research arising from such obvious self-interest. Now that herbal products have become a multi-billion dollar industry, corporate sharks and their corrupt FDA cronies are being assisted by scientists hoping to share some of the profits, at the expense of the public's freedom of choice. ---Roger Wicke, PhD, TCM Clinical Herbalist contact: www.rmhiherbal.org/contact/ Rocky Mountain Herbal Institute, Hot Springs, Montana USA Clinical herbology training programs - www.rmhiherbal.org Quote Link to comment Share on other sites More sharing options...
