Native Americans have used the Saw Palmetto berry to treat genital, urinary tract, and reproductive system problems.

The fatty acids in Saw Palmetto are thought to have testosterone inhibiting effects on the prostate.

Saw Palmetto also prevents testosterone from converting into dihydrotestosterone (DHT), which causes prostate cells to multiply, and also leads to male balding.

Saw palmetto herb prevents the binding of DHT to androgen receptors, thus playing a key role in cases of prostate enlargement, and also hair loss.
