Yerba mansa

A peppery, aromatic root of wet ground in California, the Southwest and northern Mexico, long used by the Native peoples of the region. It has not been studied in people.

Traditional use

King's American Dispensatory (1898) records that the peoples of Southern California, Arizona and Mexico used both its roots and leaves, carried the root with them and chewed it for coughs and chest complaints, and used it for fevers, diarrhea and dysentery and as a wash for saddle sores on horses. Adams and Garcia (2006) list yerba mansa among the plants the Chumash of California use for women's health.
