Senna alexandrina, commonly known as "senna" or "Alexandrian senna," is a widely used natural laxative herb globally. Research shows that senna leaves and pods contain active compounds called sennosides, which stimulate colon contractions and effectively relieve constipation. The U.S. FDA has approved senna extracts as safe laxatives when used properly. Beyond its laxative effects, senna also contains antioxidants that help detoxify the digestive system.

Using senna for health requires caution - the appropriate dosage (about 15-30 mg of sennosides daily) shouldn't be exceeded, and continuous use should be limited to 1-2 weeks. Research recommends senna as a temporary solution for acute constipation rather than long-term use. Individuals with health conditions like inflammatory bowel disease or pregnant women should consult doctors before use.

Senna is available in various forms including herbal tea, capsules, and tablets. To prepare senna tea, steep 1-2 grams of leaves/pods in hot water for 10 minutes and drink before bedtime. Effects typically occur within 6-12 hours. Drink plenty of water while using this herb to prevent dehydration and electrolyte loss.
