Introduction
Senna has been used as a laxative herb since at least medieval Arab medicine. The plant's active compounds are sennosides A and B, dianthrone glycosides that are converted by colonic bacteria to rhein-anthrone, the active stimulant of colonic peristalsis.
Industrial production proceeds by hot-water extraction of dried Senna leaves or pods, followed by purification and standardization to defined sennoside content.
Recognized as a permitted food ingredient by the U.S. FDA (with specific labeling requirements for laxative claims), the European Food Safety Authority (under specific authorization), and equivalent regulators worldwide. Listed in BP, USP, EP, and JP pharmacopoeias as a pharmaceutical laxative product.
Clinical evidence for laxative efficacy is robust and well-established. Senna is the most-prescribed natural laxative ingredient globally, with regulatory frameworks treating it as either a dietary supplement or a regulated pharmaceutical product depending on jurisdiction and concentration.
Strategic positioning serves the constipation-management market globally, both in dietary supplement laxative products and in pharmaceutical laxative medications.

- Laxative dietary supplements: the dominant commercial application globally
- Pharmaceutical applications: prescription and over-the-counter laxative medications
- Detox and cleanse-positioned dietary supplements
- Weight-management supplements (where laxative effect is part of positioning)
