Medicinal Uses: The flowers and leaves have long be used in various herbal remedies as poultices, laxatives, and to relieve cough and lung congestion. The Makah women used to eat the violet flowers and leaves during labor. The Klallam mashed the leaves and applied them to the chest or stomach to relieve pain. The crushed leaves were applied only for a few hours because they can irritate and blister the skin.
