Abstract
Sinsuntaeeuljagumdan is a medical book written by Jong-jun Lee, who was an government official in Yonsan-gun period in Chosun dynasty. This book has importance in medical history, as it was the first privately published medical book in early Choson dynasty, and written by an bureaucratic gentry, not by a professional doctor. Three versions of this book remain, among which Sungam version is printed and closest to the original, while Kyoto version is facsimile manuscript of the Sungam version. The contents of the book can be divided into three subsections, i.e. constituents and making instructions, applicable symptoms and adminstration directions, and medical records and episodes. The medical records, of these three sections, are total 8 cases, with a great value as the first ever medical record in korean history.
