Guest guest Posted January 25, 2005 Report Share Posted January 25, 2005 In the continuing investigation of ginseng and coffee: So far I have not heard back from Eastland about the statement that ginseng should not be used with coffee or other stimulants. However, I have scoured virtually every major English text that warns about drug interactions with ginseng, and I have found the following: Ginseng and coffee or other stimulants are not listed as a risk of interaction in most of the texts, including the PDR of Herbal Medicines, German Commission E monographs, Chen & Chen's Chinese Medical Herbology and Pharmacology, the new pharmacology book by You Ping Zhu, The Professional's Guide to Complementary and Alternative Medicines, and Medical Herbalism. These all re-hash the same cautions about ginseng and MAOIs and warfarin, which can be found in the original articles on Pubmed as well. Pubmed and the electronic databases on herb-drug interactions in the UCSF medical school collection and herbalgram have a variety of resources warning against the use of ginseng with various drugs, but nowhere is there anything whatsoever on ginseng being implicated with any problems with caffeine or other stimulants (though there are several studies that suggest harm reduction with the use of ginseng in conjunction with amphetamines, methamphetamine, and cocaine). However, I have succeeded in finding a two texts that say the same statement that we find in Bensky- that ginseng should not be used with coffee (or caffeine) and other stimulants (some specifically mention amphetamines). The two books that contain this statement are by Mills and Bone, " principles and practice of phytotherapy " and " the essential guide to herbal safety. " The former has no reference, and the latter refers to the reference listed below. This reference is the only source I can find anywhere, in print, in med databases, in general web searches- in Chinese and in English- that makes this claim. All books and websites that have referenced this claim refer to the same source book. Most of the websites that have this claim are pretty shoddy, but I generally like the books by Bone and Mills. To the best of my knowledge, the only book that is the source of these cautions is: Bradley, P.R. (ed.). 1992. British Herbal Compendium, Vol. 1. Bournemouth: British Herbal Medicine Association. This book is hard to come by (at least in the US). I haven't found it in any school libraries, the publisher offers no PDFs, Redwing doesn't carry it, and the book is expensive- too expensive to buy to satisfy my curiosity on this one point of contention. One website gives the abstract below as the source of the study upon which this statement is based. If this study is indeed the source of this caution, it appears to be based on a lot of extrapolation and very flimsy primary evidence. The complete absence of any published studies on pubmed or in any UCSF resources for this caution makes me suspect that it is based on assumption and repeated misinformation of secondary materials, rather than actual evidence. However, because I cannot get my hands on the British Compendium book to double-check the citation, I cannot be sure if there is more to the picture than I am finding. If anyone has access to this book, PLEASE send me or post information to clarify the origin of this statement. Contraindicating ginseng with all stimulants is a bold statement to make, given that very few other texts and no other studies seem to support the claims, and several published studies suggest that ginseng actually reduces the side-effects of several major stimulant drugs (AMPH,MA, Cocaine). The abstract listed as the rationale of this statement makes no mention of any such drugs,and it is based on saponins and isolated ginsenosides, not whole ginseng root. Likewise, if anyone can explain how the study below would contraindicate ginseng with all stimulants, that would be appreciated. If there is nothing more concrete than what I have found to support the statement that ginseng use should be avoided with coffee and other stimulants, I think that the caution is unnecessarily reactionary and assumptive, and I think it is strange that this drug interaction should be flatly stated while far more established risks are ignored. It is one thing to say that it " may " be a risk, but if one says that it " should not be used " then it should be backed by evidence. Again, we are talking about the most famous and common herbal drugs in use worldwide. Author: Hiai S, Yokoyama H, Oura H, Yano S 12/1979 Journal: Endocrinol Jpn Effects of preparations of saponin mixture and isolated ginsenosides, extracted from the root of Panax ginseng, on plasma corticotropin (ACTH) and corticosterone concentrations in rats were determined by the radioimmunoassay and competitive protein binding method. When ginseng saponin mixture was administered to rats intraperitoneally, plasma ACTH and corticosterone increased significantly 30, 60 and 90 min after the treatment. The kinetic pattern of the increase in plasma ACTH was almost parallel to that in plasma corticosterone. Isolated ginsenoside, protopanaxadiol or protopanaxatriol glycoside, also increased plasma corticosterone. The ginseng-induced increase in plasma corticosterone was suppressed by pretreatment with dexamethasone. Thus the ginseng saponin was found to act on the hypothalamus and/or hypophysis primarily, and stimulated ACTH secretion which resulted in increased synthesis of corticosterone in the adrenal cortex.

Guest guest Posted January 26, 2005 Report Share Posted January 26, 2005 I think the idea about not using coffee with ginseng may come from a theoretical rather than a research based perspective. I heard this about coffee and tea a couple of decades ago and have been toying with the ideas (off and on) ever since. It may not be so much that they create a dangerous reaction but rather that they to some extent may cancel out the benefits (or dangers) of each other, thus lessening the benefits of ginseng as well as the dangers of some stimulants. From a physiological perspective we can see that ginseng(s) are more anabolic (building up) while most of the stimulants we've mentioned in this context are more catabolic (beaking down). In TCM terms we can see ginseng as more tonic/building/increasing and coffee as more catabolic/eliminating/decreasing. Of course some stimulants may be more tonifying or detoxifying than others, but I think many of you may get my point. The 'proof' in this case may lay more in theory and experience (perhaps also if we compare what happens to the adrenal weight in separate studies after these drugs) than in a single peer reviewed study that used these compounds alone and in combination.

I have no issue with warnings based on theoretical possibilities. After all, we have very little solid data that clearly establishes true risks with herb-drug interactions. Most of what we know is theoretical or has only been reported in isolated incidents where causation is difficult to prove. I simply think that theoretical interactions should be clearly indicated as theoretical, and not presented as fact unless they can be supported by evidence. You refer to cancelling of benefits. Chinese materia medicas do mention that ginseng should not be used with tea, not because it is dangerous, but because it is considered to reduce the efficacy of ginseng. The same is said about Chinese radishes. Coffee and methamphetamines cannot be linked to the traditional wisdom that counsels against tea, since they were not even known to the Chinese historically. The concern here is that ginseng would intensify their stimulant effects, a concern that appears poorly supported by evidence. Several parameters that measure stimulating effects of methamphetamine in animals are reduced by ginseng, not increased. If our texts are saying that ginseng should not be used with coffee and other stimulants, they are not in synch with either traditional knowledge or modern science. Again, my only issue is the failure to clearly denote which risks are theoretical and which are well-established. People can make theoretical warnings whenever it might be justified, but exam texts should not present theoretical risks as established facts.
