The Food and Drug Administration hasn't approved any herbal medications for treatment of an enlarged prostate.

Studies on herbal therapies as a treatment for enlarged prostate have had mixed results. One study found that saw palmetto extract was as effective as finasteride in relieving symptoms of BPH, although prostate volumes weren't reduced. But a subsequent placebo-controlled trial found no evidence that saw palmetto is better than a placebo.

Other herbal treatments — including beta-sitosterol extracts, pygeum and rye grass — have been suggested as helpful for reducing enlarged prostate symptoms. But the safety and long-term efficacy of these treatments hasn't been proved.

If you take any herbal remedies, tell your doctor. Certain herbal products might increase the risk of bleeding or interfere with other medications you're taking.
