Used as a stimulant laxative to treat constipation by promoting bowel movements. It works by increasing intestinal motility and fluid secretion into the colon, helping to soften stool and ease its passage. Commonly found in herbal remedies derived from senna plant extracts. Often used in short-term management of constipation, especially in cases related to pain or discomfort during defecation, such as after surgery or in hemorrhoid patients. Also used in preparation for diagnostic procedures like colonoscopy to ensure bowel clearance.
