The question of what kind of diseases are related to the spleen and stomach is both simple and complex. It involves a conceptual issue: first of all, the spleen and stomach is a TCM concept, which focuses on the digestive and absorption functions of the whole body to understand diseases; while the diseases mentioned here are Western concepts, which focus on the modern physiological, pathological and anatomical basis to understand diseases. This leads to the fact that many diseases that seem to be unrelated to the spleen and stomach in Western medicine can be treated by regulating the spleen and stomach in Chinese medicine. The five most common diseases that can be treated by regulating the spleen and stomach are: Eczema: related to the spleen and stomach transporting water and dampness Eczema is a very common skin disease, and the disease is long and lingering, and the key problem of this disease is “dampness”. The key to treating dampness is to regulate the spleen and stomach. Simply removing dampness can temporarily relieve symptoms, but the disease will soon recur. Only when the spleen and stomach are healthy and able to transport water and dampness can the production of dampness be completely eliminated and the disease be cured. In fact, many skin diseases are related to dampness in the humid and hot region of Lingnan, and all skin diseases related to dampness can be treated from the spleen and stomach. Pulmonary emphysema: tonifying earth can produce gold The main characteristics of pulmonary emphysema are recurrent attacks, shortness of breath, shortness of breath, and easy coughing up of phlegm. The key problems of this disease are “lung qi deficiency” and “phlegm”, and the main treatment is usually to resolve phlegm and calm asthma during the attack period. However, this kind of people are mostly older and will recur when they encounter weather changes, according to Chinese medicine: “The spleen is the source of phlegm”. If the spleen and stomach transport water and dampness, water and dampness will not stop gathering as phlegm, and “the lung is a delicate organ”, not subject to warm tonic, so the lung should be supplemented from the spleen. As the saying goes, “if there is deficiency, the mother will be nourished”, so in clinical practice, respiratory doctors will start by regulating the spleen and stomach to treat chronic emphysema, which in Chinese medicine is called “the method of nourishing the earth to produce gold”. Postural hypotension: the spleen is the master of ascending and clearing. Many people get dizzy when they suddenly stand up after a long squat, or when they suddenly change from a sitting position to a standing position. This is postural hypotension, which is considered by Chinese medicine to be the result of Yang Qi not reaching the head and eyes and the loss of nourishment of the clear orifices. Because the spleen is responsible for raising the clear, this condition is usually treated with the method of “raising the spleen qi”, and the most famous formula is tonifying Zhong Yi Qi Tang. In addition to postural hypotension, dizziness after eating and fatigue after eating are also related to the deficiency of the Spleen’s ability to raise the qi, and can be treated along these lines. Chronic kidney disease: the acquired qi and blood nourish the innate essence Chronic kidney disease is a very difficult disease to treat, and most end-stage kidney disease requires kidney replacement surgery. Therefore, how to slow down the development of kidney disease and maintain the stability of the disease is the key to treatment. According to Chinese medicine, “the kidney is the foundation of the first day, and the spleen and stomach are the foundation of the second day”, and the foundation of the first day needs to be nourished by the qi and blood of the second day. Therefore, treatment from the spleen can help maintain the stability of kidney disease, especially for improving edema of the lower limbs and unfavorable urine discharge. Blood nourishes the five senses We often think of “liver” first when treating eye discomfort, and “kidney” first when treating ear discomfort. In fact, for chronic discomfort of the five senses, many of them are due to the inability of blood and Qi to nourish the five senses, and the cause is the spleen and stomach. Therefore, there is a “nine orifices are not in harmony, all belong to the stomach disease”, the Jin-Yuan period of the spleen and stomach of the famous doctor Li Dongyuan once created a formula called “Yi Qi Smart Tang”, is specifically used to treat deafness and tinnitus caused by qi deficiency and dimming of vision. He believed that this formula could achieve the effect of “clearing the ears and eyes”, so it was called “smart soup”.
