Some clinical studies have found that saw palmetto relieves some symptoms of benign prostatic hyperplasia (BPH), or enlarged prostate, such as difficult and frequent urination. However, at this time there are no available study results that show that saw palmetto can prevent or treat prostate cancer.

How is it promoted for use?

Saw palmetto is promoted for relieving some of the symptoms of BPH, which include difficult and frequent urination. Chemicals in saw palmetto berries called sterols are said to interfere with the ability of hormones such as testosterone to cause prostate cells to grow.

Saw palmetto is sometimes promoted by itself or with other herbs as a treatment for prostate cancer. Saw palmetto is also promoted as a treatment for prostatitis (inflamed prostate gland). Some proponents claim it increases sex drive and fertility and that it can be used to treat low thyroid function.
