Saw Palmetto is a kind of North American Palm tree, rich in plant sterols that help maintain prostate health. It is beneficial for the treatment of benign prostatic hyperplasia, the fight against male hair loss and the underlying bladder. It helps the normal flow of urine, especially during the night and provides relief from the symptoms resulting from the abnormal functioning of the prostate. It prevents the conversion of testosterone to dihydrotestosterone that causes prostate enlargement. It can also reduce fluid retention caused by histamine release (allergic reactions) and harmful chemicals.
