Saw palmetto is a plant. Its ripe fruit is used to make medicine.
Saw palmetto is most commonly used for decreasing symptoms of an enlarged prostate (benign prostatic hypertrophy, BPH), but some scientific evidence shows that it does not work. Saw palmetto is also commonly used to prevent complications from prostate surgery and for treating certain types of prostate conditions, such as long-term prostate inflammation and pelvic pain that is not caused by an infection (chronic prostatitis or chronic pelvic pain syndrome).
How does it work?
Saw palmetto doesn't shrink the overall size of the prostate, but it seems to shrink the inner lining that puts pressure on the tubes that carry urine. Saw palmetto also might prevent testosterone from being converted to dihydrotestosterone (DHT). It is thought that some types of hair loss are caused by increased sensitivity of hair follicles to DHT. Reduced levels of DHT may help prevent these types of hair loss.
