According to the Taiji thinking method in Huangdi Neijing, "One yin and one yang is the Tao and one yin and one yang is the disease", Chinese medicine divides our life state into "not morbid" and "morbid". There is obvious pain feeling when you are sick, that is, the disease state of "partial yin and partial yang"; There is no obvious pain when there is no disease, that is, the healthy state of yin and yang in the human body is relatively balanced. In addition, even if some etiology lurks in the body, it is still not pathological if it does not damage the yin and yang of the human body.
After a person enters middle age, with the decline of physiological function, various diseases begin to appear in the body, which is attributed to the imbalance of yin and yang in traditional Chinese medicine. The copula in Yi Zhuan records "the theory of knowing life and death from the origin" and "the intercourse of Yin and Yang is the beginning of things, and the separation of Yin and Yang is the end of things. Live together and die when you leave. "
Based on this, Chinese medicine believes that human health must also meet the following ten standards.
