Tea Preparation

Modern Evidence

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.
