Acorus calamus (also called sweet flag, sway or muskrat root, among many other common names) is a species of flowering plant. It is a tall wetland monocot of the family Acoraceae, in the genus Acorus. Although used in traditional medicine over centuries to treat digestive disorders and pain, it has no clinical evidence of safety or efficacy and may be toxic if ingested, and so has been commercially banned for use in food in the United States.
