The function of the intestine is to digest, absorb and transfer. On this point, Chinese medicine says this: the six internal organs to pass for use, so the real but can not be full, transferring things but not hidden. Therefore, the intestine expels the intestinal contents, which is a physiological need. In this regard, the large intestine is different from the small intestine in the intestine. The contents of the small intestine is chyme, which has a large amount of nutrients, thin and fluid; and the small intestine is thick, good blood supply, transport is not a problem. The large intestine does not have digestive functions, although it can absorb but mainly water, inorganic salts and some of the components such as bile. Its main function is to transport, and in the transport of food residues in the water pumped away part of the formation of stool to discharge. The absorptive function and speed of transport of the large intestine cannot be compared to that of the small intestine. Therefore, this part is prone to various problems. Especially in the left hemicocele, the lumen is narrower and the contents start to be drier due to its embryonic origin, so it is easy for stool to accumulate due to the slowing down of transmission. At this time, the contents of the intestine are not much different from the final stool, and a large amount of enzymes, metabolic wastes and residues contain many components that are detrimental to human health. When these ingredients are absorbed excessively, the adverse effects on the body are obvious. Therefore, a large number of products are available in the market. However, many of these products contain anthraquinones as laxatives. These laxatives have a great impact on the body when taken for a long time, especially impairing the peristaltic function of the colon, resulting in an extreme decrease in the colon’s response to stimulating laxatives and the formation of solvent-dependent constipation. This will make treatment more difficult. How to detoxify should be said to include two aspects: first, how to smoothly detoxify the stool; second, how to reduce the production and absorption of toxins. There are many aspects of this, but in brief, we should pay attention to: pay attention to the rational structure of the diet, recipes should be wide, pay attention to the mix, not to be partial. Pay attention to maintain a good intestinal environment. Generally speaking, yeast, bifidobacterium and lactobacillus are considered beneficial strains and can be adapted to supplement, and pay attention to a reasonable diet to make their colonies stable. Pay attention to regular bowel movements to minimize the residual time of feces in the body. This is a key to treating and preventing constipation. Do not do things that stimulate the intestinal tract, such as alcohol abuse, heavy smoking, eating too much stimulation, etc. Be in a good mood and move appropriately after meals.
