Cascara sagrada, also known as Rhamnus purshiana, is a small tree native to the western United States. Its bark has been traditionally used for its natural laxative properties, making it a popular herbal remedy for constipation. The name "cascara sagrada" translates to "sacred bark" in Spanish, reflecting its historical significance in herbal medicine. The active compounds in cascara sagrada stimulate bowel movements by increasing the peristaltic action of the intestines. It is often available in various forms, including capsules, powders, and teas. While generally considered safe for short-term use, prolonged consumption may lead to dependency or other digestive issues.
