which enzyme does saw palmetto inhibit
Other studies have noted that saw palmetto reduces the conversion of testosterone to DHT, its more potent form, by inhibiting the enzyme 5-alpha-reductase. Saw palmetto berry extracts also reduce inflammation and swelling by inhibiting the formation of compounds that cause these reactions. In a laboratory study, saw palmetto extract was found to slow the growth of normal prostate cells and increase their sensitivity to radiation, while not affecting prostate cancer cells.
