Senna is an herb. The leaves and the fruit of the plant are used to make medicine.

Senna is an FDA-approved nonprescription laxative. It is used to treat constipation and also to clear the bowel before diagnostic tests such as colonoscopy.

Senna is also used for irritable bowel syndrome (IBS), hemorrhoids, and weight loss.

Senna fruit seems to be gentler than senna leaf. This has led the American Herbal Products Association (AHPA) to warn against long-term use of senna leaf, but not senna fruit.
