Usnea longissima is a lichen that grows on trees and shrubs. It is used mainly as a carminative and to treat mild digestive disorders such as dyspepsia, and its active compound usnic acid gives it antibacterial and antifungal effects. Use is limited by potential toxicity; high doses can cause liver irritation, so it should be avoided during pregnancy and in persons with liver problems.
