Cascara sagrada is a natural laxative made from the reddish-brown bark of a tree (Rhamnus purshiana) native to the Pacific Northwest. It was used by various Native American tribes, who also passed their "sacred bark" on to Spanish explorers (cascara sagrada means sacred bark in Spanish). Other European settlers were also quick to adopt this traditional remedy for constipation and other discomforts. But it was not formally used in western medicine until 1877, when the pharmaceutical producer Eli Lilly & Company introduced "Elixir Purgans," a popular product containing cascara as well as several other laxative herbs.
