Abstract: Professor Zhou Zhongying, a TCM master, has been a TCM practitioner for more than 70 years and has made fruitful explorations for the treatment of viral infections in Chinese medicine. Professor Zhou emphasized that "epidemic toxin" was the key cause of new-onset pulmonary epidemics, and that external epidemic toxin triggers the latent pathogen in the pulmonary system as the basic pathogenesis. The evolution of the disease mechanism was basically under the rule of the transmission and change of the triple energizer and wei-qi-ying-blood, and he regarded the transmission and change of the triple energizer as the main channel. With the leading factor referred to the syndrome identification of the triple energizer and the importance given to the examination of the syndrome and mechanism of the disease, it was suggested to apply the principles of dispelling pathogens and resolving toxins first, combined with the concept of holism, treatment under three categories, as well as preventing before disease onset.
