Six-meridian diagnosis refers to a method of diagnosis created according to the occurrence and development of exogenous diseases, the characteristics of symptoms and the laws of transmission.
Six-meridian diagnosis belongs to one of the methods of diagnosis in Chinese medicine, which was created by Zhang Zhongjing of the Eastern Han Dynasty on the basis of the theory of six-meridian differentiation in Suwen and summarized according to the occurrence and development of exopathogens, the characteristics of symptoms, and the laws of transmutation. The six meridians refer to the sun, yangming, shaoyang, taiyin, shaoyin and syncope.
Six-meridian diagnosis is based on the physiology and pathology of the meridians and internal organs of the six meridians, and the various certificates appearing in the process of exogenous diseases are synthesized into six categories: sun disease, Shaoyang disease, Yangming disease, Taiyin disease, syncopal disease (disease caused by the invasion of exogenous diseases into the syncopal meridian), and shaoyin disease (disease caused by the invasion of exogenous diseases into the shaoyin meridian).
The six meridians are a generalization of the pathogenesis, characteristics and nature of disease at different stages in the evolution of the disease, and are used to guide clinical diagnosis and treatment.
