Cascara Sagrada Overview
Cascara sagrada is a tree native to the Pacific coast of North America. The name "cascara sagrada" means "sacred bark" in Spanish.
The bark of Cascara sagrada is used in traditional medicine most commonly as a laxative as it contains anthraquinone glycosides, which stimulate the muscles in the walls of the intestines, increasing peristalsis and promoting bowel movements. It is also used as a treatment for hemorrhoids and is sometimes used as a natural remedy for liver and gallbladder problems.
