Herbal Remedies Can Aid Prostate Health

A Review of Supplements Finds Pros and Cons

continued...

Cons: One possible explanation for why the majority of patients don't get relief? The active ingredient of saw palmetto -- like its exact mechanism -- hasn't been identified, so different formulations may produce different results, says Katz.

Red clover has long been used as an alternative treatment for a variety of conditions -- from menopausal hot flashes to psoriasis -- because it is rich in isoflavones, a protein found in soybeans. Not only is this believed to help inhibit prostate and other cancer tumors, it could help treat BPH. A product commercially sold as Trinovin (and whose manufacturer paid for Katz's study) has been found in several trials to improve urine flow and decrease symptoms by as much as 23%.

Pros: Isoflavones are suspected of helping more than BPH, but Trinovin contains four types believed to be powerful for overall health and in treating BPH and reducing prostate cancer risk.

Cons: Some studies suggest that improvements are most noticeable after one month and then continue at a much slower rate. Little or no improvement is noticed at varying doses.

Soy contains high concentrations of the same isoflavones found in red clover and is often cited as a reason why Japanese men rarely get prostate cancer.

Pros: Also believed to offers many health benefits and strong evidence of reducing prostate cancer.

Cons: For maximum benefit, it's recommend that men consume eight ounces of soy foods daily, which is impractical and would create severe gas problems, says Katz.

African tree bark (pygeum africanum) is so popular in Europe and Africa that the tree from which this treatment is harvested is now on the endangered list.

Pros: Studies show it brings relief, but how? Some show it relieves symptoms by reducing prostate swelling, while others indicate it may reduce inflammation or inhibit growth factors associated with prostate enlargement and tumor development.

Cons: Typically not a standalone treatment, and usually used in conjunction with saw palmetto.

Of course, because they are not regulated by the FDA, some experts say that many herbal supplements vary widely in the amount of active herbal extract claimed on the label. A study presented to the American Urological Association last year found that some brands tested contained less than 15% of the active ingredient listed on their label.
