Natural Factors Saw Palmetto Extract - 500 mg - The berries of the saw palmetto plant have been used traditionally to enhance male urinary and reproductive health. Saw palmetto is a natural treatment for benign prostatic hyperplasia (BPH), a common condition in men over 50. BPH can cause urinary problems and is a risk factor for prostate cancer. Although primarily used for prostate problems in men, Saw Palmetto may also benefit women who have conditions caused by excess androgen, such as hirsutism (excess facial hair) and polycystic ovarian disease.
