The Saw Palmetto is a small tree, the fruit of which is a rich source of a variety of fatty acids and hormone-like sterols. For this reason Saw Palmetto is a popular supplement for men wishing to maintain a healthy prostate and/or as a sexual rejuvenator. Its use in Benign Prostatic Hyperplasia has been extensively demonstrated in a number of studies. Significant improvements in symptoms such as poor urinary flow and night-time frequency have been well documented as comparable to prescription medication but without the associated side-effects.
