The other bioactive molecules include Emodin and Aloe-emodin as well as Flavonoids, Flavonoids, and Napthalene (Ajayi et. al., 2014).

Secondary herbal actions and mechanisms for action- The drug works by activating the immune cells of the colon.

Senna products have pro-motility properties through two mechanisms.

Senna products have stool softening properties. They modify the intestinal contractions to favor peristalsis. Inducing excess electrolyte secretion into the colon increases the colon’s water content.

It can be used for therapeutic purposes.

It is an effective drug that clears the bowels. Due to its action ability, it can be used before a colonoscopy.

It also acts as a fungicide.

Safety issues: Contra-indications, cautions, interactions. If this herb is accidentally consumed by infants it can cause severe side effects like diaper rash.

Active constituents – The main constituens responsible for medicinal action are Emodin and the hydroxyanthracene glycosides.

Secondary herbal actions and mechanisms for action- There are many quinoid substances found in the bark.

The herbal ation of hydroxyanthracene glycosides is through their ability to act as stimulant laxatives.

These stimulant effects stimulate the colon’s peristalsis.

This causes peristalsis by inhibiting the absorption electrolytes or water in the large intestinale.

This causes an increase in pressure and volume.

Part of the plant that is medicinally active – The root can be used for medicinal purposes.

Active constituents – The roots have anthraquinone and dianthrone glycosides that act as laxatives.

Secondary herbal actions and mechanisms- The herb increases peristalsis and inhibits water absorption.

Therapeutic uses- The root of this plant can be used to treat stomach problems such as diarrhea and dysentery, and for relieving severe constipation.
