"Spleen and stomach are the foundation of life", because spleen and stomach are not only the hinge group of the ups and downs of viscera and qi, but also the source of qi and blood biochemistry, and the "sea of water valleys" on which human beings depend for survival. There has always been a saying that "the kidney is the innate foundation and the spleen is the acquired foundation". Therefore, we say that health care should cultivate the spleen and stomach.
In addition, "Huangdi Neijing Lingshu the Beginning of All Diseases" says, "Wind, rain, cold and heat, not virtual evil, not harming others alone". Exogenous evil hurts people, which will change with the qi (righteousness) of the human body. Spleen and stomach theory says: "All diseases are caused by spleen and stomach failure", "Treating spleen and stomach can consolidate the five internal organs". This is the ancient people's cognition and scientific explanation of spleen and stomach. Therefore, the brand stomach is the source of maintaining sufficient qi and blood. To ensure that the spleen and stomach function is strong, we can ensure that we do not incur external evils and maintain a strong body. The formation of damp heat in human body can also be explained by this theory.
Although there are many reasons for damp heat, it can be said that all external evils in nature can cause damp heat, but the functional state of spleen and stomach is the decisive factor for damp heat. Because "the stomach belongs to yang for keeping the soil, and the brand belongs to yin for its own soil, and the gas of wet soil is also." Therefore, the evil of damp and heat, although externally received at first, is ultimately the spleen and stomach. "This is the most scientific explanation of the origin of damp heat in traditional Chinese medicine. To put it more clearly, if people eat recklessly and like to eat cool things, which will damage the yang in the body, it will lead to weakness of the spleen and stomach, insufficient transport and accumulation of moisture, which will be transformed into heat over time, and then combined with exogenous pathogens transmitted from the outside, which will first affect the transport function of the spleen and stomach and lead to the generation of damp heat in the body.
It is said in Huangdi Neijing that "moderate diet" is a very important principle of health preservation, which is very beneficial to nourishing the spleen and stomach. Usually eat less, only eat seven points full; Ensure the balanced supply of various nutrients; Eat well in the morning, eat well at noon and eat less in the afternoon; Avoid overeating; Pay attention to food hygiene, ensure clean and fresh diet, reasonably choose cooking methods, avoid overeating fried food, avoid eating greasy and sweet food, eat less irritating food, ensure good eating and better health.
When necessary, Wu Jutong pointed out in Treatise on Epidemic Febrile Diseases: "If Yangming suffers from epidemic febrile diseases and is inedible, the eater will recover. After one week 12, eat slowly. If you take the food first, don't get too full. Recover when you are full, and the recovery is heavy. " That is to say, when you have a fever (damp-heat hurts the spleen), you should "stop eating" and "eat less" when your fever goes down.
