On the Formation "Shokanron", of Chinese Great and Its Specificit Classic y Katsutoshi TERASAWA Department of Japanese-Oriental (Kampo) Medicine, Graduate School of Medicine, Chiba University, Inohana 1-8-1 Chuo-ku, Chiba 260-8670, Japan Abstract The author has attempted to reveal the evolution behind the great Chinese classic "Shokanron", through historical study. Results suggest that it originally evolved from human anatomical trials in the Xin Dynasty (AD 16). Subsequently, some person or persons engaged in these anatomical trials created a new standard, i.e. verification. This newly developed school created the methodology for describing clinical cases, according to a standard format. The followers of this school then accumulated clinical case studies over several generations, with Chochukei finally compiling "Shokanron" (AD 200). In this classic, Chochukei put forth the theory of six disease stages, and presented a manual for acute febrile disease treatment. Key words: Shokanron, Kinkiyouryaku, relativity with formulation and Sho, history
