What is the representative formula of the sweet and warm heat removal method

From the perspective of traditional Chinese medicine, when the body's yin and yang are out of balance, the treatment should be to heat up the cold and cool down the heat. Sweet and warm medicine can be very effective in treating fever. The so-called fever actually refers to fever caused by qi deficiency and fever caused by yang deficiency. The representative prescription of the sweet and warm method of eliminating heat is Buzhong Yiqi Decoction, which is composed of Codonopsis pilosula, Atractylodes macrocephala, Angelica sinensis, Tangerine peel, Bupleurum chinense, etc. So what is the representative prescription of the sweet and warm method of eliminating heat?

First, what is the representative prescription of the method of removing heat with sweet and warm herbs? Buzhong Yiqi Decoction is the representative prescription of "removing severe heat with sweet and warm herbs". "Sweet and warm medicines to eliminate severe heat" is a method of treating fever with sweet and warm medicines. The sweet and warm medicines used to treat fever mainly refer to "Qi deficiency fever" and/or "Yang deficiency fever", and the representative prescription is Buzhong Yiqi Decoction. Buzhong Yiqi Decoction is composed of Astragalus, Codonopsis, Atractylodes, Angelica, Tangerine Peel, Cimicifuga, and Bupleurum. The herbs used in the prescription are mainly sweet and warm ones, which have the effects of invigorating qi and reducing fever. Therefore, this prescription is called the representative prescription of "sweet and warm to eliminate severe heat". The fever treated by this prescription is low-grade fever. Doctors of all dynasties have different views on the pathogenesis of this type of fever.

Second, spleen yang is weak, qi and blood are deficient and fever occurs. "Treatise on Spleen and Stomach" says: "Improper diet can cause stomach problems, which will cause shortness of breath, lack of energy and high fever. Physical labor can cause spleen problems, which will cause laziness and love of lying down, with the limbs unable to move and diarrhea." It is believed that eating and overwork damage the spleen and stomach, resulting in insufficient Qi and blood, and fever. The middle qi sinks and causes fever. Ke Yunbo said: "Only Dongyuan knew that it was because fatigue damaged the spleen, the grain qi was not strong, the yang qi sunk into the yin and caused fever, so he formulated the method of nourishing the middle and replenishing qi."

What is the representative prescription of the method of removing heat with sweet and warm herbs? The patient has yang deficiency and suffers from fever due to external pathogens. Zhang Jingyue said: "Buzhong Yiqi Decoction is the unique secret of Dongyuan. This prescription uses Shengchai to help raise Qi, and uses Shenshu, Guiqi and Astragalus to help Yang Qi. This is a perfect idea. However, the meaning of tonifying Yang is also appropriate or not. For example, it is used to treat fatigue, internal injury and fever, which is to help Yang, not to induce sweating. However, it has the meaning of dispersing without dispersing. Therefore, it is most suitable for fatigue, cold, yang deficiency, malaria and spleen qi sinking. If there is no external evil cold or heat but the middle Qi is severely deficient, then Shengchai is not suitable. Because Shengchai tastes bitter and cold, and its nature is dispersing. Only those with evil can be raised and dispersed. For those with no evil and severe deficiency, even if they use pure nourishment, it may not be enough. If they also use dispersing, how can they expect success?"
