Cascara Sagrada: The Sacred Bark for Gut Health & Natural Colon Cleansing

The bark of Rhamnus purshiana has been called sacred for good reason. Named by Spanish missionaries who witnessed centuries of Indigenous reverence for it, Cascara Sagrada is the most historically documented colon-cleansing herb in the Western world — listed in the United States Pharmacopeia from 1890 to 1975 and at the center of traditional gut healing protocols ever since. Its anthraquinone glycosides speak directly to the large intestine, stimulating the rhythmic contractions that move waste through the colon while keeping the stool soft and the passage gentle. In traditional herbalism, the gut is not simply a digestive organ — it is the seat of the body's balance. You cannot heal what sits upstream of a backed-up colon. This is where healing begins.
