Obviously, the side effects of Senna leaves are still relatively strong. Excessive Senna leaves mainly have toxic side effects on the gastrointestinal system. Sennoside contained in Senna leaves can inhibit the absorption of water in the large intestine, make the intestinal contents increase sharply, and at the same time increase the tension of the large intestine, causing abdominal pain, nausea, vomiting, etc. In severe cases, it can induce upper gastrointestinal bleeding, manifested as epigastric pain, vomiting coffee-like liquid or tarry stool. Treatment of constipation is not a one-day or two-day thing, so it is necessary to choose a conditioning method without dependence and side effects. In the case of good diet and defecation habits, you can choose probiotics and prebiotics (such as Changle Fructooligosaccharide prebiotics) to recuperate together, which can be drunk by all born children, and it is very mild and has no side effects. Especially for those with bad stomach, it is very helpful to restore intestinal mucosa.
