How Senna Works?

The most effective parts of Senna alexandrina are the fruits and leaves. Senna fruits and leaf are stimulant laxatives. The cathartic properties of the leaves are more prominent than the fruit parts. Senna is an anthranoid (anthraquinone) laxative which consists of mostly sennosides. Sennosides are high molecular weight dianthrone glycosides. Sennosides are pro-drugs which are not absorbed in the upper GI, rather they are actuated by bacterial chemicals in the colon. There is very small systemic assimilation of senna. Initial confirmations also suggest that Senna powder is a stimulant that triggers the movement of water into the gut. It may also be responsible for the modulation of prostaglandins. Senna powder typically creates a diuretic impact within 8 to 10 hours after oral intake.

It was assumed that balanced doses of senna in that patient may have caused a lethal stage of hepatitis because of the patient's diminished ability to metabolize and wipe out the rhein anthrone metabolites of senna, which are thought to responsible for systemic poisonous quality. There is also some cases reports of encephalopathy, liver failure and renal deficiency in a woman who used extra dosage of senna tea. For this situation, renal deficiency and liver failure developed after more than three years of utilizing one liter per day of senna tea made from 70 grams of dried senna fruit. Chronic consumption can result in pseudomelanosis coli (color spots in intestinal mucosa) which is safe, generally turns around with suspension and is not related with an enhanced risk of developing carcinoma and colorectal adenoma. Chronic consumption has also been related with radiographically diagnosed anatomical and "cathartic colon," changes to the colon, for example, colonic dilation, and loss of colonic folds. The clinical pertinence of these findings is not confirm. Enhanced consumption of the laxative is more prone to be related with declining constipation rather than laxative dependency.
