The name “sacred bark”(Rhamnus purshiana) dates back to the 17th century, when it was so named by Spanish and Mexican explorers intrigued by the American Indians use of the bark for a wide variety of medicinal purposes. Its most important use, however, was as a remedy for constipation and for stomach upset. It is an excellent remedy for chronic constipation. Its bark is rich in hormone-like oils that promote peristaltic action in the intestines. It is not considered to be habit-forming, as it cleanses and restores natural tone to the colon. It improves the flow of secretions of the stomach, liver and pancreas and is effective on the gall bladder ducts, helping the body rid itself of gallstones. It also increases the flow of bile. CAUTION: SHOULD NOT BE TAKEN EXCESSIVELY DURING PREGNANCY: TOO STRONG A LAXATIVE, CAN CAUSE CRAMPING AND STOMACH GRIPING.
