The bark of Buckthorn contains anthraquinone glycosides, which are substances that can stimulate the peristalsis of the intestine.  These active ingredients are usually poorly absorbed in the stomach and small intestine. They are activated in the large intestine, where they are metabolized through the bacteria’s ability to transform them into anthrones, responsible for the laxative properties of the plant.
