Abstract
Ijema's four constitution theory is the result of creative succession which is originated from the "Hwangjenaegyeong(黃帝內經)", and shaped up as "Sanghanron(傷寒論)", the key of Ijema's theory would be the re-explnation of the Sameum-Samyang pattern identification. therefore, we should recognize that the four constitution theory is related to the Sameum-Samyang identification of "Sanghanron(傷寒論)". And is even on the mutual supporting relation. from this point of view, the "Dong-uisusebowon(東醫壽世保元)" could be valuated as a commentary of "Sanghanron(傷寒論)" which shows us that how to review the Sameum-Samyang identification as the point of characteristic of four constitution theory.
