[Primitive treatment of the Shanghan by Huatuo in the chapter "Shanghanmen" of Qianjinfang].

This report considers the primitive treatment of the "Shanghan" in the chapter "Shanghanmen" of the Qianjinfang. In the primitive etiology of"Shanghan", there were three stages of the recognition of disease pathogenesis, which were first the existence in fear and awe, second the poison, and the last the cold and fever. The etiology seemed to develop into that of the Shanghanlun. Furthermore, from the standpoint of therapeutics, the target for the diseases changed from influences of the external world to the body, as well. Although "Huatuo" used pills and powder formulations which have the effects of a diaphoretic, an emetic and a laxative to reject the outside diseases, he adopted the decoctions for complicated symptoms of diseases. In conclusion, the etiology and therapeutics discussed in the chapter "Shanghanmen" of the Qianjinfang are related to the formation of the Shanghanlun.
