All kinds of physiological activities of human body are carried out in a dynamic way, and "equality" is achieved through adjustment. Traditional Chinese medicine attaches great importance to the dynamic balance of yin and yang, qi and blood, and viscera, and thinks that balance can dispel diseases, strengthen the body and prolong life, so it pursues balance or harmony.
① Balance of Yin and Yang. Yin and Yang are the most important concepts in TCM. The so-called yang generally refers to being active, rising, hyperactive, or functional; The so-called yin generally refers to calmness, decline, functional attenuation, or organic aspects. Yin and Yang are in the relationship of mutual growth and decline, mutual transformation, opposition and mutual restriction. The so-called coordination of yin and yang is to stabilize the balance of yin and yang. First, it refers to the dynamic balance of normal physiological functions between various parts of the body itself; Second, it refers to the relative balance between body function and material exchange in nature. In this regard, Huangdi Neijing has long pointed out: "Yin Pingyang is the secret, and Qi is the rule; Yin and Yang are separated and refined. " It means that only when Yin and Yang are peaceful and secret can the spirit live in peace. If yin and yang are separated, people's essence will be exhausted. This is a high generalization of human physiology and pathology, which shows that harmonizing yin and yang is of great significance to maintaining human health and preventing diseases. The balance of yin and yang in human body is the premise of health and longevity, health preservation and disease elimination. Only when the balance of yin and yang in the body reaches a dynamic level can the human body maintain a healthy and stable state.
② Balance of qi and blood. Qi and blood are the material basis of human life activities. Qi can produce blood, and blood can transform qi into gas, and the two complement each other. When the balance of qi and blood is out of balance, there will be pathological changes such as stagnation and failure of qi and blood, which will lead to dysfunction of viscera and meridians. Therefore, maintaining the normal metabolism and circulation of qi and blood is a necessary condition to ensure health, and regulating qi and blood to balance it has become an important method to prevent and treat diseases.
③ viscera balance. The complex life activities of human body are dominated by five internal organs, which is a comprehensive reflection of the functions of five internal organs. Health preservation should coordinate the physiological functions of the internal organs and make them an organic whole. "Every twelve officers, don't gain or lose, so the main Ming is Ann, health is life. The world is not dangerous, thinking that the world is prosperous. " In other words, if the five internal organs of the human body cooperate with each other under the command of the heart, they can live a long life. It can be seen that health preservation must keep all functions and activities of human organs (especially heart, liver, spleen, lung and kidney) normal. In order to maintain the healthy function and normal activities of human viscera, it is necessary to adapt the five zang-organs to the external environment, to store the five zang-organs and drain the six fu-organs, and to apply the laws of the five elements theory of traditional Chinese medicine in time to correct the deficiency and excess of viscera.
