Discussion

The rhizomes of Asarum canadense are occasionally used for seasoning. Handling the leaves is said to cause dermatitis in some people.

Native Americans used Asarum canadense medicinally to treat flux, poor digestion, swollen breasts, coughs and colds, typhus and scarlet fever, nerves, sore throats, cramps, heaves, earaches, headaches, convulsions, asthma, tuberculosis, urinary disorders, and venereal disease; as a stimulant, a seasoning, and a charm; and to strengthen other herbal concoctions and heighten appetite (D. E. Moerman 1986).
