title: [The characteristics of the insidious pathogen doctrine of Wu You-xing].
abstract: The concept of insidious pathogen originated in Nei jing ( Yellow Emperors Inner Classic). Wu You-xing put forward the concept of an epidemic noxious factor on the basis of predecessors' work and gave a new connotation to insidious pathogen in the late Ming dynasty. Wu You-xing held that the cold pathogen was invisible while the epidemic noxious factor was tangible and concrete; the hidden location of the pathogen is Mo yuan, and the pathogen concealed in Mo yuan is the elementary process of epidemic disease, not hidden and not attacking. It can be treated by Da yuan yin.
