The metabolism takes place in the colon after the anthraquinone glycoside, administered orally, transits unchanged in the stomach and small intestine. At this level sugar is eliminated (D-glucose or L-rhamnose) and the active molecule is freed which acts by stimulating the cells of the colonic mucosa both in terms of motility and secretion, thus playing the laxative action.
