Discussion on the diagnosis and treatment system of 'three yin and three yang' of 'six meridians' in Shanghan Lun from Zhouyi
As one of the four classics of traditional Chinese medicine,Shanghan Lun has been highly respected throughout the ages,and its academic thought has been highly valued.Discussions on the six meridians in Shanghan Lun have been endless,which can be described as'contention and flourishing of numerous schools of thought'.The name of the six meridians is Shaoyang,Taiyang,Yangming,Taiyin,Shaoyin and Jueyin,which is originated from Huangdi Neijing,but the philosophical thinking of yin-yang can be traced back to the Zhouyi.In Shanghan Lun,"the possible recovering time of the six meridians'diseases"embodies the idea of changes in yin and yang of heaven,earth and human beings,and their mutal call and response.This paper combines the"the possible recovering time of the six meridians'diseases"and the changes of yin and yang in the trigrams of Zhouyi,referring to the'three-yin and three-yang'in Huangdi Neijing to explain the six meridians,and believes that the six meridians in Shanghan Lun encompasses the'three-yin and three-yang'diagnosis and treatment system.
