1, it should be understood that the treatment of heat syndrome with bitter and cold drugs has not alleviated it, but has become more serious. It shows that this heat is not excess heat, but deficiency heat caused by yin deficiency (mostly liver and kidney yin deficiency) and deficiency fire caused by deficiency syndrome, that is, fire contains insufficient water, so it is necessary to nourish yin and strengthen water to suppress excessive yang fire. Treating cold syndrome with pungent and hot drugs can not heal the disease, not cold, but yang deficiency, which produces cold. When yang is taken, Yang deficiency is treated by warming kidney and Yang Qi.

The treatment of deficiency-cold and deficiency-heat is not to purge its cold and heat, but to tonify yang and control yin, and tonify yin and nourish yang; "Strengthening the mastery of water, controlling sunlight, benefiting the source of fire and eliminating shadows" can achieve the purpose of regulating the decline of Yin and Yang, thus maintaining balance.

3. This sentence is an incisive annotation made by Bing Wang in Tang Dynasty according to "Yin is taken by cold, Yin is taken by heat, and Yang is taken by cold and heat" in Su Wen Zhi Zhen Da Lun, which exhausts the theory of yin-yang fire and water in cold and heat, and this method of treating deficiency has been passed down through the ages, providing theoretical basis and guidance for clinical treatment of weak diseases in later generations.
