Contemporary topic of the culture is turning to the Nature. In this situation, The Paradigms of realization about Human body and medical science are changing. The new interpretation of the value of Health is another method of recovering the Nature. Oriental medicine has mainly dealt with health preserving idealogy in origin, and pursued it. Get out of the curing medicine, the health preserving idealogy which aims to live up to one`s lifespan has been becoming the main idea of Oriental medicine. In this respect, we can extract insperation from the concept of Meebyung and preventive treatments which came from the ideas of preventive medicine in Oriental medicine. Among the researches of Meebyung in Oriental medical classics and in Oriental tri-countries, we grasped and analyzed the trends of them. In connection with the most fundamental project in Meebyung study which is to set up the concept of Meebyung, we inspected the standards which can categorize and diagnose Meebyung. In contrast with ``Ibyeong``, Meebyung in Oriental medical classics can be attained from living in harmony with the Nature, four seasons, Eum-and-Yang and the Five Phases. However the classification of Meebyung, Yogbyeong, Ibyeong in medical classics made foundation of post preventive medicine. From the various studies we can find as follws. Promting national project in Meebyung, China is trying to reestablish classifications of Meebyung, as Japanese Meebyung scholars are focusing on quantitative methods. Although there are not enough research products, Korea must absorb the products of such other countries, as to categorize Meebyung through the pattern identification system of Oriental medicine, and achieve our goal of promotion of health.
