About

Senega officinalis is a species of flowering plant in the milkwort family, Polygalaceae. It is native to North America, where it is found in southern Canada and the central and eastern United States. Its common names include Seneca snakeroot, senega snakeroot, senegaroot, rattlesnake root, and mountain flax. Its genus name honors the Seneca people, a Native American group who used the plant to treat snakebite.

Uses

This plant had many uses among Native Americans. The Cherokee used it as an expectorant and a diuretic, and for inflammation, croup, and common cold. The Chippewa used preparations of the root to treat convulsions and bleeding wounds. The Cree chewed the root for sore throat and toothache. According to Canadian botanist Frère Marie-Victorin, the Seneca may have been inspired to use the root to treat snakebite by its resemblance to the tail of a rattlesnake.
