What is saw palmetto?

Saw palmetto is a tree that is also called the American Dwarf Palm Tree, Baies du Chou Palmiste, Baies du Palmier Scie, Cabbage Palm, Chou Palmiste, Ju-Zhong, Palma Enana Americana, Palmier de Floride, Palmier Nain, Palmier Nain Américain, Palmier Scie, Sabal, Sabal Fructus, Saw Palmetto Berry, and other names.

Saw palmetto has been used in alternative medicine as a possibly effective aid in reducing complications from prostate surgery (such as blood loss or problems during surgery) and the time spent in the hospital after surgery.

Saw palmetto has also been used to treat symptoms of benign prostatic hyperplasia (enlarged prostate) such as pain when you urinate or increased urination at night. However, research has shown that saw palmetto may not be effective in treating this condition.

Other uses that have not been proven with research include hair loss, breathing disorders such as asthma and chronic bronchitis, pelvic pain, prostate disorders, common cold, hirsutism (increased facial or body hair growth in women), urination problems, prostate cancer, sexual problems, and other conditions.

It is not certain whether saw palmetto is effective in treating any medical condition. The FDA has not approved the medicinal use of this product. Saw palmetto should not be used instead of medication prescribed for you by your doctor.

Saw palmetto is often sold as an herbal supplement. There are no regulated manufacturing standards for many herbal compounds, and some marketed supplements have been found to be contaminated with toxic metals or other drugs. Herbal/health supplements should be bought from a reliable source to minimize the risk of contamination.

Saw palmetto may also be used for other purposes not listed in this product guide.
