Saw palmetto, or Serenoa repens, is a dwarf palm native to southeastern North America. Its red berries have a long history of traditional use for treating urinary and reproductive problems. Today, saw palmetto is the third-top-selling herbal supplement in the US and is backed by an ever-increasing body of research.
Saw palmetto has been used since the early 1700s to treat prostate inflammation. Its extracts are now valued around the world by men with enlarged prostates. This condition is called benign prostatic hyperplasia (BPH) and affects more than 50 percent of men by age 60. By helping to ease inflammation in the prostate gland, saw palmetto is believed to slow the development of BPH and related growth—especially when combined with other nourishing prostate remedies like lycopene and selenium.
