Zhang Zhongjing wrote Treatise on Febrile Diseases in Han Dynasty, which comprehensively analyzed various syndrome groups in the evolution of exogenous diseases, and summarized the pathological changes, the trend of cold and heat, and the rise and fall of pathogenic factors, and divided them into six meridian diseases of Sun, Yangming, Shaoyang, Taiyin, Shaoyin and Jueyin. For thousands of years, it has effectively guided the dialectical treatment of traditional Chinese medicine.

the syndrome of six meridians is a reflection of pathological changes of meridians and viscera. Among them, the syndrome of three yang diseases is based on the pathological changes of six fu organs; The syndrome of three yin diseases is based on the pathological changes of five internal organs. Therefore, the syndrome of six meridians basically summarizes the pathological changes of viscera and twelve meridians. The application of six meridians syndrome differentiation is not only limited to the diagnosis and treatment of exogenous diseases, but also has guiding significance for the treatment of tumors and internal injuries.

therapeutic principles and prescriptions

1. Treatment of the sun by syndrome differentiation

(1) Apoplexy: it is a syndrome of deficiency of the exterior of the sun, which means that the health is strong and the camp is weak, and the camp is not harmonious with the health. To treat apoplexy, it is only necessary to reconcile the camp and the health and sweat out the disease, and Guizhi Decoction can be used.

(2) Typhoid fever: it is the exterior syndrome of the sun, and it can't be sweated due to dense acupoints, and it's not enough to get rid of pathogenic factors without sweating, so Mahuang decoction can be used.

(3) Epidemic febrile diseases: internal heat and body fluid injury, which is not treated in Treatise on Febrile Diseases. There are many reasons for internal heat. Those who hurt body fluid are mostly caused by excessive yang burning and consuming yin. In addition, the yin blood is not cool enough, and it usually starts from the liver and stomach, and it is inappropriate to develop externally, while the hair is far away from the near. Therefore, it is urgent to replenish the middle and fill the essence to make up the consumption, and cool the blood and purge the heat. And look for the evil of the six meridians, assist in attacking and cutting to cure it, and collect more internalization. As for the evil way, when the turbid door is opened with cold to drain dysentery, if it is drained, the middle jiao will be lighter than the cold, while the remaining yang will be returned by the meridians, and the middle jiao will be solved, and the grass boat will borrow the arrow to make the world peaceful.
