In this article I describe the Ch'ing palace medical archives in the First Historical Archives with illustrations drawn from the archives collection as well as relevant historical materials. This article is intended to be a general and practical guide for those desiring an illustrated survey of how to utilize these archives for various research interests. Also it is going to critically discuss the scholarly utilization of these archives. This article consists of four parts: it begins with introducing and discussing the current status and the filing policies of the medical archives. At this part I detail the differences between the original and the published version of the medical archives, and provide sources complementary to the issues. At the second part I explain that the medical archives were originally bureaucratic documents. It would be helpful to clarify their functions and roles before conducting researches based on these archives. Accordingly at the third part I show the historians' polar opposites toward the verity of the contents in the archives and discuss the reasons. Finally I compare the archival records and relevant sources to concretely explain the value of the medical archives and their limitation. Therefore, other than being useful to medical history and the history of imperial family, this study also reminds scholars of critically useing archival sources.
