Red Clover Found to be Best Alternative Therapy for Treating EnlargedProstate

STAMFORD, Conn., Jan 30, 2003 /PRNewswire-FirstCall via COMTEX/ -- A review article published in the current issue of Journal of Alternative and Complementary Medicine (volume 8, number 6) finds that based on current scientific evidence, isoflavones from red clover extract appear to be the best alternative treatment for prostate health. Alternative therapies are known to be less expensive than conventional prescription treatments for problems such as enlarged prostate, or benign prostate hyperplasia (BPH), which affects most men in their senior years.

The article's author is Aaron Katz, M.D., Director, Center for Holistic Urology, New York Presbyterian Hospital and Assistant Professor of Urology, Columbia University School of Medicine. The Journal of Alternative and Complementary Medicine is peer-reviewed and published monthly.

Prostate Problems Very Common

As men age, problems affecting the prostate become more common. More than half of the men in the United States between the ages of 60 and 70 and as many as 90 percent between the ages of 70 and 90 have symptoms of BPH(i), which include problems urinating, difficulty emptying the bladder, and frequent urination. The American Urological Association recommends that all men over 50 and all African American men over 40 have their prostates checked annually.

BPH is a non-cancerous growth of the prostate gland. Despite the availability of conventional medicine and surgery for BPH, many men are turning to natural alternatives because some of the medications take several months to work or do not work at all(ii), have side effects in a large percentage of patients(iii)(iv)(v), or are expensive(vi). Surgery is not always indicated(vii) but when it is, many men are reluctant to undergo the procedure for fear of impotence or other potential side effects.

Why Phytotherapy?

According to the review, men in Eastern countries have much healthier prostates than men in Western countries. The increased prevalence of BPH and prostate cancer among Western men may be the result of Western men not eating enough isoflavone-containing foods(viii)(ix)(x). By comparison, Japanese men are known to have higher plasma levels and urinary excretion of plant-based ("phyto") isoflavones(viii). Researchers believe this difference in dietary intake is a main cause of prostate health issues in Western men.

Conclusion Favors Red Clover

To better understand the science behind alternative botanical approaches to the treatment of prostate-related health concerns, Dr. Katz reviewed the epidemiological data and published studies supporting five popular herbal treatments (curbicin, saw palmetto, soy, red clover, and pygeum africanum).

Dr. Katz reported that scientific evidence exists to support the claim that isoflavones relieve the symptoms of BPH. Red clover, in the form of Trinovin(R), was said to be particularly effective, because it is the only supplement found to have all four of the isoflavones shown to be promising in treating prostate symptoms (genistein, formononetin, daidzein, and biochanin). These same isoflavones are found in abundance in the Asian diet in a variety of foods. Trinovin was also the only prostate supplement found in a National Institutes of Health funded study to meet its label claims for containing isoflavones in the most beneficial form.

Trinovin is manufactured by Novogen, Limited (Nasdaq: NVGN). Novogen has become one of the world's leading research and development companies in the field of isoflavones and human health. This knowledge has made Novogen the leader in phenolic drugs research for novel anti-cancer compounds. More information can be found at www.novogen.com .
