How does NSI® Senna 940 mg work?
The Senna shrub (Cassia angustifolia) is found in Africa, India, Pakistan, China, Egypt and the Sudan. The leaves and pods are the medicinal parts of the plant. They contain compounds called anthraquinones, which are powerful laxatives. They increase the peristaltic movements of the colon by their local action upon the intestinal wall, leading to evacuation of the bowel.

Senna contains hydroxyanthracene glycosides known as sennosides, which stimulate colon activity producing a laxative effect. These glycosides also increase fluid secretion by the colon, which softens the stool and increases its bulk.

Senna is one of the few herbal medicines approved by the United States Food and Drug Administration (FDA) for over-the-counter use and may be one of the most widely used herbal medicines in the United States.

NSI® Senna 940 mg is an effective and potent purgative with its action being chiefly on the lower bowel.  It generally produces bowel movement in 6 to 12 hours.

NSI® Senna 940 mg is better because it:
-- Provides natural, effective relief of constipation
-- Contains the most potent and highest quality nutrients
-- Is a better value than other brands
