Is saw palmetto effective?

Saw palmetto is rated as "possibly ineffective" for enlarged prostate by the Natural Medicines Comprehensive Database. Several small studies have found that it is effective, but a research review found no evidence that it works any better than a placebo (sugar pill).

It is likely safe for most adults, but children and pregnant women should avoid it, as it affects hormones. As is true for all dietary supplements, saw palmetto has not been evaluated by the FDA for safety, effectiveness or purity.
