Is there any way to adjust the imbalance between yin and yang?

The occurrence of diseases is fundamentally due to the relative imbalance of yin and yang in the body, so there is a saying that "one yin and one yang is the Tao, which is actually a disease". Regulating Yin and Yang is to damage the surplus of Yin and Yang, make up for its decline and promote its relative coordination and balance according to the specific situation of Yin and Yang imbalance.

Excess of yin and yang means excess of yin or yang. Su Wen's Theory of Yin and Yang should be like a big picture says: "Yin wins Yang disease, and Yang wins Yin disease." Excessive yin cold is easy to damage Yang Qi, and excessive yang heat is easy to damage vaginal fluid, so when regulating excessive yin and yang, we should pay attention to whether there is corresponding yin decline or yang decline. If the yin or yang is excessive, and its counterpart is not weak, the method of "excess damage and deficiency" can be adopted, that is, clearing yang heat or warming yin cold. If its counterpart is damaged, it should take into account its shortcomings and cooperate appropriately to support yang or benefit yin.

Both yin and yang are declining, that is, yin deficiency or yang deficiency. Yang deficiency and cold, yin deficiency and heat. Yang is not enough to control yin, which is mostly deficiency-cold syndrome of yang deficiency and yin excess; Yin is not enough to control yang, mostly due to deficiency-heat syndrome of yin deficiency and hyperactivity of yang. Yang disease cures Yin, and Yin disease cures Yang, that is, when coordinating the decline of Yin and Yang, the method of "supplementing its deficiency" should be adopted. If yang deficiency leads to excessive yin cold, it is advisable to replenish yang and control yin, so-called "the source of virtual fire eliminates yin"; If yin deficiency leads to excessive yang heat, it is necessary to nourish yin and control yang, the so-called "master of strong water to control yang"; If both yin and yang are deficient, they can be supplemented to achieve a physiological relative balance. Because yin and yang are interdependent, we should also pay attention to "seeking yang in yin" and "seeking yin in yang" when treating the symptoms of deficiency of yin and yang, that is, adding and matching tonics appropriately while replenishing yin.

Yin and Yang are the general principles of syndrome differentiation, and all kinds of pathological changes of diseases can be explained by the changes of Yin and Yang. Pathologically, the exterior and interior are different, fluctuating up and down, cold and heat advancing and retreating, evil excess and deficiency, disharmony between qi and blood, imbalance between camp and health, etc. Are manifestations of yin-yang imbalance. Therefore, in a broad sense, all kinds of therapeutic methods, such as relieving exterior symptoms and attacking interior, ascending and descending, clearing cold and warming, tonifying deficiency and purging excess, harmonizing ying and Wei, and regulating qi and blood, also belong to the category of harmonizing yin and yang. Therefore, "Su Wen Yin Yang Yi Xiang" said: "Examine its Yin and Yang, treat it with gentleness, treat it with yang disease, and treat it with yin disease. Set its blood and keep its hometown. " It is pointed out that adjusting yin and yang is one of the important therapeutic principles.
