Saw Palmetto

In: LiverTox: Clinical and Research Information on Drug-Induced Liver Injury [Internet]. Bethesda (MD): National Institute of Diabetes and Digestive and Kidney Diseases; 2012.


Saw palmetto is a popular herbal medication and extract derived from the fruit of the low growing, small palm, Serenoa repens, which has fan shaped leaves and is native to Florida and the Southeast United States. Currently, saw palmetto is used mostly for symptoms of benign prostatic hypertrophy. Saw palmetto has been implicated in rare cases of clinically apparent liver injury, but its specific role in causing liver injury remains uncertain.
