How It Works

Cascara bark is high in hydroxyanthraquinone glycosides called cascarosides. Resins, tannins, and lipids make up the bulk of the other bark ingredients. Cascarosides have a cathartic action that induces the large intestine to increase its muscular contraction (peristalsis), resulting in bowel movement.2

How to Use It

Only the dried form of cascara should be used. Capsules providing 20–30 mg of cascarosides per day can be used. However, the smallest amount necessary to maintain soft stool should be used.3 As a tincture, 1/4–1 teaspoon (1–5 ml) per day is generally taken. It is important to drink eight 6-ounce (180 ml) glasses of water throughout the day while using cascara. Cascara should be taken consecutively for no longer than eight to ten days.4
