Laxative capsule, usually can be effective in about 6-8 hours after taking, but there are individual differences, the onset of action time is slightly different. Laxative belongs to the category of proprietary Chinese medicines, and its main ingredients are Senna and Cistanche. Senna is a commonly used laxative, which can stimulate gastrointestinal peristalsis, thus providing defecation. Cistanchis contains a large amount of dietary fiber, which can increase intestinal water and promote gastrointestinal peristalsis, thus increasing the discharge of stools. However, the dosage of these two herbs in Laxative is not particularly large, so the effect of diarrhea is not as fast as that of tomato leaf alone. Its laxative effect is mild, usually 6-8 hours to have a laxative effect. Be careful not to blindly apply laxatives for laxative, first of all, to clarify the cause of bowel irregularity, if intestinal obstruction, the application of diarrhea-inducing drugs may aggravate the patient’s gastrointestinal symptoms, abdominal pain, or even induced intestinal perforation.
