The laxative effect of TCM warming and stomach tonics is to adjust the function of the gastrointestinal tract as a whole, so that the function of the digestive tract can be improved systematically and as a whole, taking the functional state of normal human digestion as the standard, and to realize the transformation of pathological defecation into physiological defecation. In other words, the goal of this treatment is not simply to improve the bowel movement, but to improve the overall digestive function and at the same time to improve the bowel movement. Clinical practice over the years has confirmed that this treatment not only has good near-term and long-term effects on laxation, but also has no additional pain during the laxation process and improves digestive function as a whole. In contrast, traditional laxative treatment is very different from warming and stomach tonics. It uses bitter-cold herbs to stimulate the intestinal wall, causing contraction and peristalsis of the intestinal canal to shorten the residence time of feces in the intestinal tract and make it pass quickly; or it increases the volume of digestive juices in the intestinal canal to soften and thin the dry feces, so that the resistance of feces passing through the intestinal canal is reduced and it is easy to pass and discharge. It is easy to see that traditional Chinese medicine laxative because the drugs used are bitter-cold laxative, it is suitable for patients with cold solid evidence. Patients with constipation in clinical practice are mostly patients with deficiency cold certificate. Patients with constipation also see symptoms of cold biological characteristics such as cold stomach and abdomen, anorexia and cold, etc. According to the rules of Chinese medicine, when these symptoms are not used cold drugs, these symptoms are often ignored by doctors. Therefore, the current treatment pattern of heat-clearing and fire-removing, laxative medicine as the mainstay is created. It believes that the existence of constipation is the abnormality of the digestive tract function, and when treating it, more consideration is given to the mechanism of the existence of this symptom and treating it, so that if the abnormality of the digestive tract disappears, the constipation will go away, instead of just laxative. Another point that patients can feel is that the effect of warming and stomach laxative is different from that of traditional laxative. In traditional laxative, there is slight abdominal pain and downward pressure before and during defecation, but in warming and stomach laxative, there is no discomfort during defecation. The reason for this is that the intestinal canal is stimulated, while the warm tonic and stomach laxative does not stimulate the intestinal canal.
