CAS No.: 84650-55-5
Latin Name: Rhamnus purshiana (D.C.).
Description: 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).
Today, numerous over-the-counter laxatives feature cascara sagrada as a key ingredient. Because it's so mild, the herb is frequently combined with stronger laxatives, such as aloe vera latex. To work properly, the bark must be carefully prepared cured for at least one year or heated and dried to speed up the aging process. Aging is essential because the fresh bark is very irritating to the gastrointestinal system, causing vomiting and intestinal spasms.
