Saw Palmetto

Saw Palmetto (Serenoa repens) is a dwarf palm that grows over wide areas of the southeastern United States. It produces a green-yellow oblong berry, up to one inch long, which turns bluish to black when ripe. Concentrated extracts are typically standardized to contain 85–95% fatty acids and phytosterols. Saw Palmetto has traditionally been used for helping with prostate problems.

Health Benefits

Ripe fruit from Saw Palmetto has been used to ameliorate symptoms of early stage benign prostatic hypertrophy (BPH: enlarged prostate), prostate infections, or urination in men.1,2 Several human studies have indicated the effectiveness of Saw Palmetto in decreasing urinary tract and Benign Prostatic Hyperplasia (BPH) symptoms in men.3-7 Saw Palmetto remedy in conjunction with B-sitosterol and Vitamin E may also reduce nocturia (waking up to urinate during sleep) and symptoms of BPH as defined by the American Urological Association.8
