Abstract
From ancient times to the present, many doctors have different understandings of the interpretation of the “Time for Relief” of Six Channel Disease in Treatise on Febrile Disease. We try to analyze this from Yin-Yang theory, the mutual generation and mutual restriction of five phases and the transformation of twelve terrestrial branches and six climatic factors in The Inner Classic of Emperors, so as to provide a reference for medical workers to further study and clinical application of Treatise on Febrile Disease.
