The root collected in the fall. In the prairie regions of the state, occasional to frequent as far south as the northern slopes of the Ozarks. Yields the drug echinacea, which contains resins but no alkaloids. Used as alterative, stimulant, diaphoretic, and sialagogue. [Brauneria pallida (Nutt.) Britt., Kansas snakeroot, and B. purpurea (DC.) Britt., black Sampson, occur in prairie regions and along railroad tracks. More abundant than the foregoing species, they probably can be collected without discrimination.].
