Hi everyone, I received this info from David Winston a few days ago, I've read

articles by Jonathan Treasure like this about PubMed. This is really sad to see

educated people acting like politicians!

 

Last month a paper was published in the Journal of the American College of

Cardiology. This paper, by Tachjian, et al, Use of Herbal Products and

Potential Interactions In Patients With Cardiovascular Diseases, purports to be

an authoritative look at the risks and dangers of people using herbs along with

cardiac medications. Unfortunately while there are very real risks, especially

patients taking blood thinners such as Warfarin and anticoagulant herbs, this

paper does a tremendous disservice to anyone trying to gain accurate information

on the topic.

 

The poor quality of this work raises several important issues. First, the three

authors (two of which are MD's) obviously have no experience with herbal

medicines and their writing this paper is about as valid as me writing a paper

on the use of pharmaceuticals in treating heart disease. I am sure they are

very good cardiologists, but in my opinion they should stick to what they know

and were trained for.

 

The second issue is this work is so full of errors one wonders how it ever got

through a peer review process. Many people have suggested there is a double

standard in peer review medical journals when it comes to negative articles on

herbal medicine. Since so many of these articles are so seriously flawed one

could easily assume there is an anti-herb bias and that anything saying herbs

are dangerous will get published no matter how erroneous it may be. While I

will not go as far as to say there is an active conspiracy against herbs, I

would say that in the general medical community ignorance and fear of herbs and

their uses is so vast and so broad that these journals are incapable of

adequately vetting these articles. I would even put forth a " radical "

proposition that perhaps in the future any article about herbal medicine in a

medical journal or any study of herbal medicines should actually include a

clinical herbalist as part of the design and research team. Unfortunately I

doubt researchers or editors will actually take my suggestion seriously.

 

Some of the significant errors found in this article include:

 

· Foods such as soy milk and grapefruit juice are listed as foods.

 

· Also included as " herbs " are Chan Su (Chinese toad skin extract),

Gossypol (an experimental male contraceptive derived from Cotton seed, only used

in China), Tetrandrine (an alkaloid extracted from Stephania tetrandra and not

available in the U.S. or Europe), and Yohimbine (an alkaloid extracted from

Yohimbe, Yohimbine is a prescription drug).

 

· The authors also include Uzara root, an herb so obscure I have never

heard of it and Gynura divaricata which is a little-known folk medicine in

China.

 

· Beyond these " small faults " the article mentions two cardiac glycoside

containing plants, Strophanthus (misspelled as Storphanthus in the article) and

Oleander, neither of which is available in the U.S. or Canada as a herbal

product.

 

· Finally, the authors have selectively chosen (it is possible sheer

ignorance is at fault here) to list adverse effects of herbs, even when more

recent studies have disproven these theoretical risks. Many books and articles

suggest that there might be a risk of administering Hawthorn along with cardiac

glycosides. A 2003 human trial (Tankanow, et al, 2003), clearly showed that

there was no interaction between these 2 medications.

 

· Also cited is the widely discredited clinical report by Siegel on Ginseng

Abuse Syndrome. In this paper the author noted many effects of Ginseng use

including hypertension, behavioral changes and diarrhea, all of which turned out

to be caused by excessive coffee drinking by test subjects.

It is truly sad when such uninformed and flawed papers are given the medical

" seal of approval. " It creates and adds to the medical profession's and

public's fear of herbs, most of which are very safe. Secondly, it spreads

misinformation which, as we see by the Siegel article published in 1979, is

difficult to erase. And finally it obscures the accurate information that could

benefit the medical profession, such as possible interactions between St. John's

wort and Digoxin or garlic and Dan Shen (Salvia miltiorrhiza) with

anticoagulants.

 

The last part of the article discusses the lack of regulatory oversight and

quality control with herbal products. I whole-heartedly agree the authors of

this and similar articles need more regulatory oversight and quality control as

this article is ample evidence of neither in many medical journals.

Hi Z'ev,

 

I'm pretty sure this is what David is writing about;

 

http://content.onlinejacc.org/cgi/content/abstract/55/6/515

 

I'll try to contact him and be sure. It looks like you have to pay to get access

to the full article.
