Cascara sagrada (Rhamnus purshiana, sacred bark, pushiana, purschiana bark, persiana bark,
chittam bark) contains emodin, which has antiviral and anticancer properties.
Cascara sagrada is used primarily as a laxative and stimulates the peristaltic action of the intestine.
This wavelike motion moves waste through the intestine. This property helps restore the proper tone and health of the intestine by pushing waste out of diverticula pouches that develop in the intestinal
wall. This helps restore the mucous lining and health of the intestine. Cascara sagrada has been
used in traditional medicine to improve stomach, liver, and pancreas secretions and to break up and
remove gallstones from the gallbladder.
