Senna is a traditional herbal ingredient derived mainly from the leaves and pods of Senna plants. It has a long history of use in traditional herbal practices and is best known for its natural laxative properties. Senna contains compounds called sennosides, which stimulate bowel movements and are commonly used for short-term relief of occasional constipation. Senna is typically available as teas, powders, capsules, extracts, and other herbal preparations. Because prolonged or excessive use may cause dehydration, electrolyte imbalance, or dependence on laxatives, Senna is generally intended for short-term use. Appropriate dosage and professional guidance are important for safe use.
