Saw palmetto, a widely used herbal dietary supplement, does not reduce urinary problems associated with prostate enlargement any better than a placebo, according to research funded by the National Institutes of Health.
The study was published Sept. 28 in the Journal of the American Medical Association.

This was an important study since saw palmetto is widely used for prostate health. The study was a double-blind randomized placebo-controlled clinical trial, long term (over 2 years) and included a good sample size. High doses were used. The effectiveness claims of this OTC supplement just went down the toilet.
