Do saw palmetto supplements help with enlarged prostate?

Numerous human trials report that saw palmetto improves symptoms of benign prostatic hypertrophy (BPH) such as nighttime urination, urinary flow, and overall quality of life, although it may not greatly reduce the size of the prostate. The effectiveness may be similar to the medication finasteride (Proscar®) with fewer side effects. Although the quality of these studies has been variable, overall they suggest effectiveness. Saw palmetto has not been thoroughly compared to other types of drugs used for BPH, such as doxazosin (Cardura®) or terazosin (Hytrin®). Most available studies have assessed the standardized saw palmetto product Permixon®. Although a 2003 study by Willetts et al. reported no difference over a 12-week period and a 2006 well-designed study by Bent et al. reported no difference over a 12-month period, overall the weight of available scientific evidence favors the effectiveness of saw palmetto over placebo.
