"Byunjeung-okham(辨證玉函)" is composed of four volumes, Eumjeung-yangjeungbyun(陰症陽症辨, Vol.1), Heojeungsiljeungbyeon(虛症實症辨, Vol.2), Sangjeunghajeungbyun(上症下症辨, Vol.3) and Jinjeunggajeungbyun(眞症假症辨, Vol.4) (卷之一 "陰症陽症辨", 卷之二 "虛症實症辨", 卷之三 "上症下症辨", 卷之四 "眞症假症辨"). It is based on the 74 types of disease symptoms, and compared to "Byunjeungrok(辨證錄)", it is rather brief and concise. Thus, its name, "Byunjeung-okham". This study researched vol.2, "Heojeungsiljeungbyun(虛症實症辨)", which is organized according to the deficiency and excess pattern of 20 disease patterns, such as cough. The disease pattern system mentioned in this book is unique compared with other disease pattern systems. The role of the kidney is especially emphasized, and the application of the Five-phase[五行] theory is very original. Consequently, it contributed greatly in the process of broadening the disease pattern system of Traditional Korean Medicine.
