Predators
''Corydalis flavula'' can be found throughout most of the eastern half of the US and also parts of Canada. It is a pioneer species that requires disturbance to thrive. Disturbance helps to keep the overarching canopy at the right density for its light requirements. Because of this requirement it is threatened primarily due to human land use which often results in conversion of habitat to mowed lawns and managed streams and rivers, removing the disturbance and canopy the plant requires.
Uses
''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. Chinese medicine uses plants in this genus as a pain reliever, muscle relaxant, and to slow the gastrointestinal system.References:
