Its components are found in senna (Senna alexandrina, also known as Cassia angustifolia), where sennoside A and sennoside B are present in equal amounts, and in rhubarbs (Rheum rhabarbarum), where sennoside A predominates. It has a role as a laxative and a cathartic. It contains a sennoside A and a sennoside B."}]
