Some native groups chewed the roots or made them into a tea to treat chest ailments (tuberculosis and asthma), rheumatism, sore throats, and stomach ulcers. Coltsfoot leaves and flowers were steeped in hot water to make a tea for people suffering from diarrhea. Strong doses have been reported to cause abortion. Coltsfoot has been widely used as a medicine over the years. It was once the official sign of the French apothecaries. Also known as "Sweet Butterbur".
