Sennoside B
CAS: 128-57-4
CAT: 5094
Abstract
Sennoside B (CAS 128-57-4) comes from the Senna plant (Cassia species). Senna is a popular herbal laxative that people can buy without a prescription.
Studies show that senna stimulates the colon. It triggers contractions and reduces water absorption in the intestines. These actions help relieve constipation quickly and effectively.
Doctors often recommend sennosides to treat constipation in children and elderly people. They use sennoside B alone or combine it with sorbitol or lactulose for better results.
Sennoside B contains many bioactive compounds. The product is usually safe and well tolerated when used correctly. However, taking high doses for too long can cause problems. In some cases, it may lead to liver injury.For safe use, always follow the recommended dosage and do not take it for extended periods. Short-term use works best for occasional constipation relief.
Planta Analytica supplies high-purity sennoside B as an analytical reference standard. This product helps laboratories accurately measure senna content in herbal medicines and dietary supplements.
