What is Saw Palmetto for?

Saw Palmetto is the name of a palm-like plant that grows in the southeast US. The berries are then extracted to use for medicinal purposes, as it has been found to be effective in lowering a male hormone called dihydrotestosterone (DHT). DHT is a male hormone commonly found in patients with benign prostatic hyperplasia (BPH) and male hair loss. Saw palmetto works by inhibiting an enzyme to lower the concentration of DHT in the body. It may be helpful to treat symptoms of benign prostatic hyperplasia, probably in combination with other drugs like Tamsulosin.

Saw palmetto is available as capsules. The recommended dosage is 160 mg twice daily or 320 mg once daily, taken at the same time of the day.

What are the side effects of Saw Palmetto?

Pharmacist Tips:
