What is saw palmetto?
Saw palmetto comes from a palm-like plant that grows in the southeast United States. The berries of this plant are used to make the capsule form of saw palmetto. Saw palmetto is also known as American Dwarf Palm Tree, Baies du Palmier Scie, Cabbage Palm, Chou Palmiste, Ju-Zhong, Palma Enana Americana, Palmier Nain, Palmier Scie, Sabal, Serenoa, and other names.
Saw palmetto blocks certain effects of certain hormones in the body and also has some anti-inflammatory actions.
Saw palmetto has been used in alternative medicine as a possibly effective aid in preventing complications from prostate surgery (such as blood loss or problems during surgery) and reducing the time spent in surgery and in the hospital after surgery.
Saw palmetto has been used to treat symptoms of enlarged prostate (benign prostatic hypertrophy, or BPH), such as increased night-time urination or decreased urinary flow. However, research has shown that saw palmetto may not be effective in treating this condition.
Other uses not proven with research have included treating sore throat, cough, cold symptoms, asthma, bronchitis, migraine headache, male-pattern baldness, chronic pelvic pain and prostate swelling, bladder problems, prostate cancer, and other conditions.
It is not certain whether saw palmetto is effective in treating any medical condition. Medicinal use of this product has not been approved by the FDA. Saw palmetto should not be used in place of medication prescribed for you by your doctor.
Saw palmetto is often sold as an herbal supplement. There are no regulated manufacturing standards in place 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 purchased from a reliable source to minimize the risk of contamination.
