The cascara sagrada bark was already used by native American Indians, and it soon drew the attention of the Spaniards who colonized California. Like the bark of the alder buckthorn, a similar species that grows in Europe, cascara sagrada must not be consumed until it has been dried for one year since, when fresh, it has toxic effects.

Healing Properties
The bark of this tree contains anthraquinone glycosides (emodin, chrysophine), similar to those of the alder buckthorn, and other glycosides (aloin, chrysaloin). Its intense purgative effect, more drastic than that of the alder buckthorn, is due to the combined action of all these active components.
Though a potent laxative, in therapeutic doses, it is pretty well tolerated and does not produce cramps or colitis. Unlike chemical laxatives, it can be used for extended periods. This plant is thus ideal for chronic constipation or intestinal atony, especially for elderly people. It also has mild cholagogue and eupeptic properties, thus promoting emptying the gall bladder and easing digestion.
Cascara sagrada is the best herbal laxative for people suffering from chronic constipation. It is one of the best, most typical, and safest plant-based laxatives. It stimulates peristalsis by irritating the bowels. However, if overused, it can become habit-forming. The bitter properties of the plant stimulate secretions of the whole digestive tract—including the pancreas, stomach, gallbladder, and liver.
Cascara sagrada is beneficial for gallbladder problems, mainly enlarged liver and intestinal gas. Additionally, it is used for jaundice, indigestion, and gastric and intestinal disorders. Because of the herb’s overwhelming bitterness, please do not take it as a tea to use it for a mild laxative effect; instead, use capsules or tincture.
Note: Ensure the bark is at least one year old before use. Please do not confuse cascara sagrada (Rhamnus purshiana), at times called “buckthorn,” with (Rhamnus frangula). They’re both helpful medicinal herbs but different.
