Abstract
We study on the HYUN-GOG's main principles of Differentiation of Syndromes. HYUN-GOG insisted upon the main principles of Differentiation of Syndromes based on the individual-physiology. The system of Differentiation of Syndromes was composed of the Korean oriental medicine's physiological system. The main principles of Differentiation of Syndromes was mutually explained for the standpoint of eight principal syndromes(differentiation of pathological conditions in accordance with the eight principal syndromes) and the system of Syndrome-complexes based on the physiological system. BON-HER(original deficiency-syndrome), BON-HAN(original cold excess-syndrome), BON-YEOL(original heat excess-syndrome), the three representative syndrome-complexes is previously carried out the details of Differentiation of Syndromes. And the oriental medicine history was rearranged centering around the theory of Differentiation of Syndromes by HYUN-GOG. The theory of Syndrome-complexes was closely connected with prescription by the presentation of the basic organical prescription for the three representative syndrome-complexes.
