Origin & History
Cascara (Rhamnus purshiana) is a deciduous tree native to the moist coniferous forests and mountainous river valleys of western North America, particularly California, Oregon, and British Columbia. Its bark has been historically valued for its potent laxative and digestive cleansing properties.
“In Indigenous healing systems of North America, Cascara was known as the 'bitter bark of release,' used in seasonal purification rites and for illness recovery. It was deeply associated with clearing what no longer served the body, both physically and spiritually.”Traditional Medicine

Scientific literature, including in vitro and clinical studies, supports Cascara's well-established laxative effects, primarily attributed to its anthraquinone glycosides.

Frequently Asked Questions
What is Cascara Bark?
Cascara Bark, from the Rhamnus purshiana tree, is a well-known natural stimulant laxative. It works by stimulating muscle contractions in the intestines, helping to promote a bowel movement and relieve occasional constipation.
How long can I safely take Cascara Bark?
Cascara should only be used for short-term relief, typically for no longer than one week. Long-term use can lead to dependence, where the bowels become reliant on the stimulant, and can cause serious electrolyte imbalances.
How is Cascara different from Senna?
Both Cascara and Senna are stimulant laxatives containing anthraquinones and work similarly. Cascara is often considered to be slightly milder than Senna, causing less cramping, but individual reactions can vary. Both should only be used for short-term relief.
