Abstract
There were so many discussions about the importance of Ungi theory, but little about its application. But, in Korea, there is particular Ungi medical system. I studied the 25 organic constitutions and their prescriptions and concluded like below. In "Ounyukgihanihakbogam(五運六氣漢醫學寶鑑)", "Ounyukgihak(五運六氣學)", there are 25 organic constitutions, and each of them has its basic prescription. Like above, In "Ounyukgigeummoksuhwatosangsaengsanggeukbeop(五運六氣金木水火土相生相克法)", "Ounyukgigyeongheomcheobang(五運六氣經驗處方)", and "Jesaenglon(濟生論)", there are also 25 organic constitutions, and each has basic prescription. Moreover, there are so many prescriptions for diseases can often occur. I classified these as three groups, "Ounyukgihak(五運六氣學)" is groupⅠ, "Ounyukgihanihakbogam(五運六氣漢醫學寶鑑)" is Ⅱ, and the other books is Ⅲ, and compared each basic prescriptions. GroupⅠand Ⅱ use similar prescriptions, but groupⅢ doesn't. This Ungi medical system has little relation with "Somun(素問)". And I couldn't find the organic constitutions based on Ungi from other country's oriental medical book. 25 organic constitutions have much sameness in prescriptions. These prescriptions are used in real medical system, but not wide. Of course, it needs more research, but it has another position in oriental medicine.
