 "Corydalis flavula" belongs to the Ranunculales order, an order of plants that often contains many alkaloids that make plants distasteful to toxic.Early use by Native Americans involved inhalation of the smoke of a charring plant.Because early American medicine gleaned some of the aboriginal understandings of the power of plant alkaloids like heroin for pain and belladonna for hearing issues, it was used for things like staunching a bleeding wound, and as an anti emetic.
