Herbal Remedies Can Aid Prostate Health

A Review of Supplements Finds Pros and Cons


"Saw palmetto is usually the first line of therapy against BPH -- at least by patients or their spouses," quips Franklin Lowe, MD, MPH, associate director of the Department of Urology at St. Luke's/Roosevelt Hospital and chairman of the American Urological Association's Complementary & Alternative Medicine Committee. "Most patients are taking it before they come to their urologist's office to find out if they should be taking it." Still, many urologists endorse it use for patients with early, troubling symptoms.

Pros: This herb brings relief in about one in three patients, with a suspected effect similar to Proscar, by blocking the production of a hormone that causes the prostate to grow. "Nobody really knows exactly why it works, because studies are conflicted on the suspected mechanism," says urologist Eric K. Seaman, MD, FACS. "What is clear is that it helps a lot of people, and there is no documented evidence of any side effects. I know a urologist who was waking up at least three times a night because of BPH, and since taking saw palmetto, he's up only once a night. So even if the majority of patients don't get a benefit, they don't lose anything either other than a few dollars."

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.
