As a prostate remedy, saw palmetto offers no benefit

A new study at the NIDDK’s Division of Kidney, Urologic and Hematologic Diseases has found that men with enlarged prostates who took higher doses of herbal supplement saw palmetto had no relief from urinary problems.

The current study confirmed results of an earlier trial, which found that a standard daily dose of 320 mg provided no greater symptom relief than placebo.

Prostate enlargement, also called benign prostatic hyperplasia (BPH), can cause frequent urination, a weak or intermittent urine stream and an inability to empty the bladder completely.
