Cascara Sagrada by Vitabase
The Cascara Sagrada for this product is aged for one year to optimize the active constituents. The bark is peeled from the trees of the pacific Northwest. To work properly, the bark must be carefully prepared - cured for at least one year or heated and dried to speed up the aging process. Aging is essential because the fresh bark is very irritating to the gastrointestinal system, causing vomiting and intestinal spasms. Click here for more information.

Medicinal uses and health benefits of cascara sagrada bark


Cascara sagrada comtains anthraquinones (including emodin, chrysophanic acid, aloe-emodin, cascarosides A, B, C, and D). The anthraquinones stimulate the bowel, leading to evacuation after approximately six to ten hours. Cascarosides have a cathartic action that induces the large intestine to increase its muscular contraction (peristalsis), resulting in bowel movement. Cascara sagrada is a mild and safe laxative. Laxatives are products that promote bowel movements. Laxatives increase the action of the intestines or stimulate the addition of water to the stool to increase its bulk and ease its passage. Laxatives may act by increasing peristalsis by irritating the intestinal mucosa, lubricating the intestinal walls, softening the bowel contents by increasing the amount of water in the intestines, and increasing the bulk of the bowel content. The hydroxyanthracene aglycones inhibit water and electrolytes absorption from the colon and induce active secretion of water and electrolytes into the intestinal lumen. Pressure in the intestine is increased and peristalsis stimulated due to the increased volume of contents. The laxative effect of cascara sagrada is augmented by a pronounced bitter stimulating effect, particularly active in promoting liver function and bile secretion.
