Abstract
Objective : Zhang, Zhongjing(張仲景)'s Sanghanlun(傷寒論) is based on Six-channels system(六經) to classified a disease. But the notion of Six-channels system seems to be a very various angles. For example, Meridian and collateral theory(經絡說), Viscera and Bowels theory(臟腑說), Grade theory(段階說), Surface theory(地面說), Symptoms theory(症候群說), Six-disease theory(六病說), Eight principle pattern theory(八綱說) and all the rest of it. Above all things Meridian and collateral theory was very frequently quoted to explain the Six-channels system(六經). But it's true notion is not restrict to a meridian vessel(經脈). Method : I will try to describe the Sanghanlun's Greater yang disease(太陽病) through the Ke-qin(柯琴)'s Taiyangbingjie(太陽病解), and I would like to point out that the existing perception that Greater yang(太陽) is connected with Bladder meridian(足太陽膀胱經) is wrong. Result : Ke-qin's Taiyangbingjie explained the greater yang disease was connected with Heart(yang within yang), which was located in the top half and the outer layer of the body. In addition to the presence of the diaphragm or lungs are involved with. Conclusion : Practical meaning of greater yang disease is not connect with Bladder meridian, but it is related to the Heart and Lung for maintain the Nutrient and defense circulation (營衛循環).
