SMUTH L contains lactitol, also known as lactulose, which is a laxative used to relieve constipation. By drawing water into the intestine, lactulose softens and makes the stool easier to pass. It is not absorbed by your body and cannot be digested, therefore it is carried to the colon unaltered. Enteric bacteria breakdown it to acids, which aids in water retention in the colon. This expands the intestinal volume in the colon and indirectly increases bowel movement. High doses are used to prevent and treat brain impairment caused by liver disorders.Disclaimer : For More Details, Contact Your Physician
