There are two different types of Cascara, Cascara Amarga and Cascara Sagrada. The barks of both plants contain anthraquinone glycosides called cascarosides that have laxative qualities. The cascarosides act on the large intestine, where they inhibit water and electrolyte re-absorption from the colon.
Cascara Sagrada is a member of the Buckthorn family and often forms a part of the herbal formulae for dyspepsia, digestive complaints and haemorrhoids. Sagrada is a stimulant laxative but it also helps to eliminate constituents causing griping pain.
