Cassia Acutifolia

Senna is a member of the pea family and a native plant of the areas of Africa, the Middle East, and India. The parts of Senna used as an herb are the leaf, seed, and pod of Alexandria Senna and Tinnevelley Senna. Many botanists collectively refer to them both as Senna Alexandrina. Today it is cultivated commercially in the Middle East and the Tennevelly region of Southern India.


Traditionally Senna was used in love sachets in the Middle East. In China, they named senna Fan-Hsieh-Yeh, which means “foreign-country laxative herb.” Senna (Cassia Acutifolia) is one of the oldest known varieties of herbal medicines used in mankind’s herbal medical history. Senna is included in most pharmacopeias of the world and was first used by Arabian physicians in the ninth century. Two Arabian physicians, Serapion and Sesue, are said to have given the herb its Arabic name ‘Senna’ and employed it as a purgative. By 1640, Senna was cultivated and utilized in England for its cathartic properties.

Senna’s Chemical Constituents and Actions

Senna is a purgative, similar to aloe and rhubarb in having as active ingredients anthraquinone derivatives and their glucosides.   Senna is cathartic and should be used in combination with other cathartic herbs of its kind to work best (see below Senna Works Best) for bowel elimination. It should be used by itself only in cases of acute constipation. Senna has an anthraquinone that stimulates the nerves of the bowel wall encouraging peristaltic action.

The primary chemical constituents of Senna include anthraquinone glycosides (sennosides aloe-emodin and rhein), beta-sitosterol, flavones, essential oil, mucilage, mucin, resin, tannin, and tartaric acid. The sennosides irritate the large intestinal lining, causing peristaltic action of the smooth muscles that push stool through the intestine causing bowel evacuation. It also assists in the temporary retention of fluid in the large intestine, thus contributing to softer stools. The pods are milder in their effects than the seeds of Senna as they contain less of the resin responsible for griping.

Both the leaves and pods of Senna are used in many over-the-counter pharmaceutical preparations. Senna is actually a common ingredient used to make some sore throat remedies. The herb is most often used in powder form, drank as a tea, or taken as a supplement. Senna is one of the few herbal medicines approved by the United States Food and Drug Administration (FDA). Thus, Senna’s over-the-counter use makes it one of the most commonly used herbal medicines in the United States (for added safety look for the words Certified Organic on the label).

Be sure you check all the medications that you are taking for what are called contraindications. That is a list of things you do not want to take with your medication before anyone begins taking a supplement or herb. If you are unsure then be sure you check with your attending physician.

Breast Feeding

No adverse effects have been seen in breastfed infants whose mothers were receiving Senna.   The American Academy of Pediatrics considers that Senna (Cassia Acutifolia) is therefore usually compatible with breastfeeding.
