Senna Extract Liquid

Product Name : SennaExtract Liquid

Senna is a small perennial shrub. It is native to tropical Africa and is now cultivated throughout that continent. Senna is obtained from two species: the frist one is known commercially as Tinnevelly Senna and grown predominantly in India. and the pods of Senna are used, the pods having a gentler action. The active principles of Senna are anthraquinone glycosides (Sennoside A and B), which act primarily on the colon. Added to this there are about 10% of mucilage, and tartrates, which inhibit the absorption of fluid from the gut and thus enhance the laxative action. Stimulation of muscle contraction may extend to the uterus, so that senna should not be given during pregnancy. Senna is a reliable and quite powerful laxative. Small doses of 1-2 g will result in pultaceous stools being produced with in 5 – 7 hours. Higher doses of 2-4 g will act more rapidly, but the stools will then often be liquid and accompanied with abdominal pain. The side effects are even more marked if the does is increased to 8-12 g, when severe colic, nausea and vomiting may develop. The fact that senna leaves are not well tolcrated in large doses is largely due to the resins they contain. Senna leaf tea should therefore always be made with cold water, leaving it stand for some time, so that it is a maceration rather than a tea, and the resine do not go into solution to any extent. Remaval of the resin reduces the colic-inducing effect of Senna leaves. On the other hand, the laxative action is also reduced. Deresinated senna leaves will often be very useful for highly irritable bowels.
