First of all, it should be noted that the spleen and stomach in TCM are not the spleen and stomach in modern medical anatomy. In terms of physiology and pathology, the spleen and stomach in TCM include the entire digestive system, far beyond the spleen and stomach in the anatomical sense. According to TCM, the spleen is the origin of the postnatal period and the source of Qi and blood biochemistry. After birth, all life activities depend on the nutrients ingested by the spleen and stomach. If one is born with a deficiency, he can make up for it through the latter day, which can also prolong his life; if one is born with a good innate condition, he will become sick and lose his life if he does not pay attention to the spleen and stomach. In Chinese medicine, an important function of the spleen is to transport and transform. If the spleen can transport and transform water and grain essence (water and grain essence is the food we eat), then the digestion and absorption function of the body can be sound, so as to provide enough raw materials for the production of essence, qi, blood and fluid, so that the organs, meridians, limbs and bones, as well as tendons, flesh, skin, hair and other tissues can be fully nourished. On the contrary, if the spleen’s function of transporting water, grain and essence is reduced, the body’s digestive and absorption functions will also be out of order, so the spleen is said to be the source of Qi and blood biochemistry. The spleen and stomach live in the middle of the earth and are closely related to other internal organs. Diseases of the spleen and stomach can easily affect other internal organs; the liver, heart, spleen, lungs and kidneys correspond to wood, fire, earth, gold and water, and the five organs are related to the five elements, which can easily lead to the phenomenon of disease transmission. Therefore, there is also the saying that “if the spleen and stomach are injured, all four organs will be lifeless”. The spleen is the master of rising and clearing, and the spleen is the master of rising, so that the nutrients such as water, grain and essence can be distributed to the whole body to perform their nutritional functions. The stomach is responsible for lowering turbidity. Food into the stomach, by the gastric decomposition, must go down into the small intestine, in order to further digestion and absorption, so the stomach to descend for and. The spleen and stomach are located in the middle jiao, is the hub of lift, its lift affects the internal organs of the yin and Yang lift, so the spleen and stomach healthy and healthy, the internal organs can be harmonious and coordinated, the vital energy can be abundant. Therefore, when regulating the body, special attention is paid to regulating the spleen and stomach qi. In the five elements, the spleen belongs to the earth, which is located in the center and is balanced in all directions. The spleen and the stomach, a yin and a yang, are mutually exclusive. The spleen and the stomach participate in the digestion and absorption of food together. The Yellow Emperor’s Classic of Chinese Medicine says, “The spleen and stomach are the officials of the granary, and the five tastes come out of it”, which means that the spleen and stomach are compared to the granary, which can take in food and export fine nutrients for the whole body. People are based on water and grain, the stomach is the main receiver of water and grain, and the spleen is the main transporter of fine nutrients, which shows that the spleen and stomach occupy an extremely important position in the human body.
