Tea Information

Research Summary

Senna has moderate evidence as a short-term stimulant laxative for occasional constipation, via anthraquinone glycosides (sennosides); it is not a treatment for chronic constipation, IBS, weight loss, or any disease, and overuse causes dependency, electrolyte loss, and laxative-abuse risk. Best used briefly and with guidance.

Evidence levels reflect the currently available scientific literature and may change as new research emerges. Where evidence is limited or conflicting, this is stated plainly.
