Chinese medicine treatment of spleen and stomach disease focuses on balancing the spleen and stomach in the middle jiao, connected by membrane, spleen qi should rise, stomach qi should descend, spleen likes to be rigid and dry, stomach likes to be soft and moist, the opposite is true. In accordance with Wu Jutong’s principle of “the middle jiao is like a balance, not flat and restless”, attention should be paid to the adaptation of cold and temperature, and to the adjustment of both elevation and lowering, and to the same principle of deficiency and reality. First, to protect the stomach qi: stomach qi is also known as spleen and stomach qi, stomach qi, the spleen and stomach is the essence of the latter, stomach qi is also the essence of the latter. Because the five viscera and six internal organs are endowed with gas in the stomach, stomach gas can nourish the gas of the five viscera, and among the gas of the five viscera, the kidney gas is most closely related to the gas of the stomach. The kidney is the innate qi, the spleen and stomach are the latter qi, the kidney qi is the root of the stomach qi, and the stomach qi nourishes the kidney qi. Insufficient innate qi can also be nourished by the acquired qi. A healthy person has sufficient stomach qi, which is manifested by good appetite and full of energy. If a person eats and drinks as usual during illness, it indicates that the stomach qi has not been injured; if the appetite gradually improves and the amount of food increases, the stomach qi is restored. If you are seriously ill for a long time and see a loss of appetite, reduced food intake, or even do not think about eating, it is a manifestation of the failure of stomach qi, and the prognosis is not good, as the saying goes, those who get the grain will prosper, those who lose the grain will die. Second, the regulation of lifting and lowering of qi: lifting and lowering is the basic form of physiological activity of the body, and the spleen and stomach is the hub of the lifting and lowering of qi, so the regulation of lifting is also the principle of treatment of spleen and stomach disease. Ye Tianshi pointed out that “the spleen should rise to be healthy, and the stomach should descend to be harmonious”. Spleen and stomach disease can be manifested in three forms: lift and lower, lift and lower, and lift and lower disorder. Third, the regulation of yin and yang: spleen is the yin of the organs, the stomach is the yang of the bowels, this is the relative division of the nature of different organs and bowels. However, in terms of the nature of their susceptibility to disease, moisture is a yin evil easy to hurt the spleen Yang, dry is a yang evil easy to hurt the stomach Yin. Therefore, in terms of treatment, warming the spleen and nourishing the stomach, drying dampness and clearing heat all belong to the category of regulating yin and yang. The treatment of spleen and stomach diseases is also based on the principle of restoring the relative balance of yin and yang by supplementing their deficiencies and dipping their excesses. In the treatment of spleen and stomach diseases, Li Dongyuan emphasized the promotion of spleen-yang and Ye Tianshi emphasized the nourishment of stomach-yin, while the treatment principles of supporting spleen-yang and nourishing stomach-yin are both aimed at replenishing the deficiencies of the spleen and stomach in response to the strength and weakness of yin and yang. Nourishing stomach yin can harmonize the yin and yang of the stomach, so that it can descend without reversing, and can overflow essence for the spleen to disperse essence and return to the lungs. The emphasis on supporting spleen yang and nourishing stomach yin does not exclude supplementing spleen yin and benefiting stomach qi, but because there are primary and secondary lesions of spleen and stomach yin and yang deficiency, in treatment Fourth, focus on balancing the middle jiao: spleen and stomach, connected by membrane, spleen qi should rise, stomach qi should descend, the spleen likes to be rigid and dry, the stomach likes to be soft and moist, the opposite is true. Therefore, the treatment of spleen and stomach diseases should be based on Wu Jutong’s principle of “the middle jiao is like a balance, not flat and unsettling”, paying attention to cold and temperature, and adjusting both up and down, deficiency and reality.
