brief introduction

Treatise on Febrile Diseases, written by Zhang Zhongjing in Han Dynasty, comprehensively analyzes various syndromes in the evolution of exogenous diseases, summarizes their pathological positions, cold and heat trends, and the rise and fall of pathogenic factors, and divides them into six pulse diseases: sun, Yangming, Shaoyang, Taiyin, Jueyin and Shaoyin.

For thousands of years, it has effectively guided the dialectical treatment of traditional Chinese medicine. Syndrome of six meridians is a reflection of pathological changes of meridians and viscera.

Among them, the syndrome of Sanyang disease is based on the lesions 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 the twelve meridians. The application of six meridians syndrome differentiation is not limited to the diagnosis and treatment of exogenous diseases, but also has guiding significance for the treatment of tumors and internal injuries.
