Ma Ren Wan is a proprietary Chinese medicine, which is mainly used in clinical practice for the treatment of constipation and dry bowel. Chinese medicine is about using the right medicine and selecting the right prescription for the right condition. If the constipation is caused by a lack of fluid in the intestinal tract and dry heat in the stomach and intestines, this medicine can be used. However, due to the different conditions and constitution of each patient, the time of its effect varies, generally in 3-5 days can play a significant role. In fact, there are many clinical causes of constipation, such as poor dietary habits, certain gastrointestinal diseases, and poor bowel habits, which are all risk factors for constipation. Relatively speaking, the elderly and women are more prone to constipation. This is mainly due to the fact that these groups are less active, eat too finely, and eat a smaller amount of food, which is less stimulating to the peristalsis of the gastrointestinal tract, resulting in slower peristalsis of the gastrointestinal tract, longer stay of food residues in the intestine, and repeated absorption of water in food residues, resulting in dry and hard stools that are difficult to discharge. In addition, certain diseases of the gastrointestinal tract can cause intestinal obstruction, such as tumors and rectal prolapse, which can cause bowel obstruction. Certain medications can also cause constipation, such as antidepressants, diuretics and certain analgesic drugs. Patients with constipation should not blindly apply laxatives. It is recommended to go to a regular hospital for relevant auxiliary examinations, such as abdominal plain film, colonoscopy, barium meal examination, etc., to clarify the causes of constipation, exclude organic lesions, and then choose the medication according to the condition. In daily life, constipated patients can appropriately increase exercise, eat more food containing coarse fiber, and avoid the abuse of laxatives.
