Sennas have for millennia played a major role in herbalism and folk medicine. Alexandrian senna (S. alexandrina) has long been traded commercially.
Senna glycosides, or sennosides, are used in modern medicine as laxatives.Senna drugs contain the dried leaves of S. alexandrina. The glycosides increase gastric fluid secretion and bowel motility, producing laxative action. Senna preparations are available in powders, granules, tablets, oral infusions, and syrups. It is also available in combination with the dietary fiber psyllium to add bulk to the bowel contents. The products are only recommended for short-term use, and chronic use and abuse of senna has been associated with organ failure.

Several Senna species are used as herbal remedies in Nigeria to treat various conditions, including constipation, fungal skin infections, and haemorrhoids.
If you have fewer than three bowel movements per week or your stools are harder than usual, you may have constipation, according to the University of Maryland Medical Center. Stress, chronic disease, or certain medications may cause constipation. Inadequate fiber or fluid intake and lack of physical activity can also contribute. If constipation lasts for more than a few days, talk to your doctor about what might be causing it.
Senna and Constipation
Senna may relieve constipation by stimulating the muscles of the colon to push fecal matter through more quickly. It may also help your colon absorb water to soften stool. You may expect a bowel movement within six to 10 hours of taking senna, according to the National Cancer Society. Active compounds in the senna plant, called sennosides, may be responsible for its laxative effect.
