Saw Palmetto 101
Saw palmetto is used mainly for urinary symptoms associated with an enlarged prostate gland, also called benign prostatic hyperplasia, or BPH. It is also used for other conditions such as chronic pelvic pain, bladder disorders, decreased sex drive, hair loss, and hormone imbalances.
What the Science Says
The data has been mixed when it comes to determining the true effectiveness of
saw palmetto. Several small studies suggest that saw palmetto may be effective
for treating BPH symptoms. But in 2006, The National Center for Complementary
and Alternative Medicine (NCCAM) and the National Institute of Diabetes and
Digestive and Kidney Diseases co-funded a large study of 225 men with
moderate-to-severe BPH. The study found no improvement among men who took 320
mg saw palmetto daily for 1 year, versus those who took a placebo.
There is not enough scientific evidence to support the use of saw palmetto for reducing the size of an enlarged prostate or for any other conditions. It also does not appear to affect readings of prostate-specific antigen (PSA) levels. PSA is protein produced by cells in the prostate. The PSA test is used to screen for prostate cancer and to monitor patients who have had prostate cancer.
Side Effects and Cautions
Saw palmetto may cause mild side effects, including stomach discomfort. Some
men using saw palmetto have reported side effects such as tender breasts and a
decline in sexual desire.
Remember: It is important to inform your health care providers about any herbal or dietary supplement you take, including saw palmetto. This helps to ensure safe and coordinated care.
