We often see patients in the clinic who complain of loose and unformed stools and discharge large amounts of undigested food residue. At first glance, this sounds disgusting, but in fact it is the patient’s own digestive function that is wrong. In normal times, our food enters the body, is digested by the stomach, digested and absorbed by the intestines, and finally the metabolic waste is excreted in the form of feces. When there is a problem with our body and the food is not digested, the above symptoms occur, which in Chinese medicine is called “complete grain does not dissolve”. The diarrhea with this characteristic is called “food (yin sun) diarrhea” in Chinese medicine. Yellow Emperor’s Classic of Internal Medicine” cloud: spring injury in the wind, summer food and drainage. It is also said that if there is cold in the intestines, there will be food diarrhea. The “Treatise on Diseases of the Time” says: “Spring injury to the wind, …… depressed in the spleen and earth, the earth is weak and cold, then the wind and wood more winning, and the spleen and earth is not the main ascending, but sinking and for diarrhea.” Translated into vernacular, it means that if you feel the wind evil in spring, the most common is a cold, if the cold is not completely cured, the wind evil may remain in the body, to your spleen and stomach cold evil is heavy, you may have diarrhea. So, when will be the time when the spleen and stomach cold evil is heavy? First, when we first recover from a cold, the qi and blood are not particularly strong, and the evil has not been completely removed, so if we eat cold fruits and melons at this time, it will create an environment where the spleen and stomach are cold. Second, it is summer, the body’s Yang Qi tends to table in summer, the body Yang Qi is relatively insufficient, people will naturally eat some cold fruits and melons because of the hot weather, this time, the spring cold latent in the body of wind evil will take advantage of the opportunity to come out of the crime, wind and cold hostage to each other, resulting in the occurrence of diarrhea. Therefore, the cold, we should actively treat, not to leave hidden problems, spring cold especially so. In addition, in summer we should also pay attention to moderate intake of melons and fruits Oh!
