Cascara Sagrada

Cascara is obtained from the dried bark of Rhamnus purshianus (Rhamnaceae). The dried bark is aged for about a year and then is powdered for use in supplements and other products. It has been used for its laxative effect by Native American tribes and Spanish cultures since the 1800s. It continues to be used as a laxative stimulant and bowel cleanser, and is safe for short term use.
