What do I Need to Know About Cascara Sagrada?
Cascara sagrada is an herb with laxative effects that has a long history of use in Native American medicine. It is made from the bark of the Rhamnus purshiana, a type of buckthorn shrub native to western North America, spanning parts of British Columbia and the northwestern United States. While cascara sagrada has been a popular ingredient in over-the-counter medications for over 10 years, the United States Food and Drug Administration (FDA) banned its use in over-the-counter products in 2002 because of inadequate data concerning its toxicity.
