Abstract
The education of traditional Korean medicine has been challenged for the lack of illustrated explanation of fundamental and pivotal concepts. The purpose of this study was to make suggestions for the diagrammatic concept on Qi. Thorough review was made performed to elucidate pictorial concept of Qi with medical classics and textbooks on the human physiology based on the central theories including Yin-Yang, five phase, and correspondence between nature and human. Medical terminology and its taxonomy for the Qi were examined here. We proposed more clarified terminology and related metabolic pathways for the design of schematic illustration of Qi. This study would contribute to the development of introductive drawings and educational materials fit for the apprentice.
