Saw palmetto is used to treat benign prostatic hyperplasia (BPH) symptoms in numerous western countries. Aging men often are affected by BPH and experience symptoms including frequent urination, difficulty maintaining or starting urination, need to urinate during the night, and urine leakage.
Research supports that saw palmetto is effective in treating BPH in some individuals. Although saw palmetto seems to provide relief for BPH symptoms, it does not reduce the prostate’s size.
Saw palmetto is used by some herbalists as a diuretic, an anti-inflammatory, a sedative, and an antiseptic. Various reports claim that saw palmetto may also stimulate hair growth.
Although there is no supporting scientific research, some women use saw palmetto to increase breast size.
