BENIGN PROSTATIC HYPERPLASIA. A lipid hexane extract of saw palmetto has been shown to be generally superior to placebo,1,2 and of similar efficacy to finasteride3 in the treatment of benign prostatic hyperplasia. A systematic review of randomised studies of various saw palmetto extracts concluded that they improve urological symptoms and flow measures.4 However, a more recent double-blind study5concluded that treatment for one year was not superior to placebo for improving urinary symptoms and objective measures.
