What is the so-called "imbalance between Yin and Yang"?

The imbalance between yin and yang is a pathological state in which the two sides lose coordination and balance. The imbalance of yin and yang is a pathological change that will inevitably occur in the process of the occurrence and development of any disease, so it belongs to the general outline of pathogenesis. The imbalance of yin and yang is the imbalance of yin and yang coordination in the body. Yin-yang theory emphasizes the mutual generation, mutual restraint, mutual utilization, growth and decline balance and mutual transformation between Yin and Yang, and maintains a dynamic balance within a certain range. The movement and change of Yin and Yang are eternal, and the coordination and balance of Yin and Yang are relative. Achieve a relative balance in endless changes, which is manifested in the coordination and unity of human life activities, so as to be disease-free. The imbalance between yin and yang is one of the most basic principles of all diseases. There is no dispute between evil and righteousness in the occurrence of diseases. There are yin and yang in healthy qi, and yin and Yang Can are also divided into evil. The development of disease is nothing more than the rise and fall of good and evil, and can also be summarized by the rise and fall of yin and yang. So any disease can be explained by yin-yang imbalance. The imbalance of yin and yang is also a summary of the changes in the pathogenesis of the body. The location of the disease is not the viscera, meridians, qi and blood, camp and health, but the pathogenesis is nothing more than the damage of healthy qi and excessive pathogenic factors. When the zang-fu organs are sick and have abnormal functions, the movement of qi will be abnormal. Zang-fu organs, meridians, qi, blood, ying and Wei can all be explained by yin and yang. Qi moves up and down into Yang and down into Yin. Therefore, the mechanism of disease change is nothing more than yin-yang imbalance. The essence of the imbalance between yin and yang depends on the quantitative advantages of both sides, that is, the dominant position. Yang is active in ascending, and its nature is hot, so the pathogenesis of Yang is characterized by ascending, dispersing, jumping, and appearing heat phenomenon; Yin governs quietness and descending, and is cold in nature, so the patients with yin excess are mainly sedimentation, coagulation and quietness, and the phenomenon of yin cold is more obvious. The imbalance between Yin and Yang Can sums up the physiological dysfunction of human viscera, meridians, qi, blood, camp and Wei and the dispute between good and evil. Because the meaning of Yin and Yang is relative and the content is very extensive, the pathological changes of Yin and Yang imbalance are extremely complicated, but its basic manifestations are: excessive Yin and Yang, weakness of Yin and Yang, mutual loss of Yin and Yang, repulsion of Yin and Yang, transformation of Yin and Yang, and death of Yin and Yang. Yin and Yang are relative concepts, therefore, the imbalance of Yin and Yang in diseases refers to disunity, or positive or evil words; Or the cause, or the symptoms, all of which must be carefully determined.
