This medicine transforms into rheinanthrone by action of enteric bacteria in large intestine to show diarrhea effect and lowers intestinal tension.

It is usually used to treat constipation (except spastic constipation) and as a cathartic after use of the anthelmintic.



It is a typical large intestine stimulant laxative. It is made from a medicinal plant called senna and contains anthraquinone-based active ingredients. This strain is powerful, but its drawback is that it becomes less effective if you continue to drink it for a long time.
