Cascara Sagrada — Spanish for “sacred bark” — has been used for centuries by Native American peoples of the Pacific Northwest as a traditional botanical. The aged bark of Rhamnus purshiana contains naturally occurring anthraquinone glycosides (cascarosides) and has a long history in North American herbal practice. Like all anthraquinone-containing barks, cascara must be properly aged before use to reduce the harsh irritant compounds present in fresh bark.
