Ethnobotanical Uses and Other Facts
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.
Food Uses: The flowers can be eaten and used in salads, potherbs, or tea. Some violet species are used for decoration on certain types of food such as cake. In the southern US the leaves are often added to soups as a thickening agent.
