Abstract

Saw palmetto is an extract from the berry of the plant Serenosa repens. It is an important food source for the Native Indians. The fruit of this herb contains free fatty acids and phytosterols. Β-sitosterol present in alcoholic extract of the fruit is estrogenic and can relieve bladder and urinary disturbances associated with stage I and II benign prostatic hyperplasia (BPH). Recent studies show that saw palmetto has a mild toxic effect on prostate cancer cells. It blocks testosterone from reaching prostate cells without affecting the level of testosterone in circulation. Hence, it preserves sexual function yet prevents the development and enlargement of prostate cancer and benign prostate. Saw palmetto has also been claimed effective in increasing breast sizes, sexual desire in both male and female and in acting as a mild diuretic. Due to the presence of a high molecular weight polysaccharides and flavonoids, it also possesses anti-allergic and anti-inflammatory activity.
