Senna is an anthranoid type stimulating laxative. The laxative effect is due to the action of sennosides and their active metabolite, rhein-anthrone, in the colon. There are two different mechanism of action: 1. An influence on the motility of the large intestine: By the inhibition of water and electrolyte absorption from the large intestine, which increases the volume and pressure of the intestinal contents, resulting in propulsive contractions. 2. An influence on secretion processes: Stimulation of active chloride secretion increases water and electrolyte content of the intestine.
