Cascara Sagrada Bark (Rhamnus purshiana) is a traditional North American botanical widely recognized for its use in digestive support. Historically used by Indigenous communities and later adopted into Western herbal practices, Cascara Sagrada is known for its naturally occurring anthraquinones, which contribute to its gentle laxative effect.
