Abstract
Objectives The purpose of this study is to understand the formation of Jogakdaehwang-tang(JD-T)'s patholoy and the compositional change of it in Sasang Constitutional Medicine(SCM). Methods The pathologic condition in which JD-T was used and the change of its composition was studied in SCM Results and Conclusions 1. Jogak and Daehwang in "Dongmuyoogo Haedong" were presented with Ungdam because of the common purpose flowing the energy of lung. Therapeutic method for exogenous Ungibyeong in "Dongyisusebowon sangchobongwon" was subdivided into Hangwul's treated by Ungdam, and the heat pattern featuring contagious cold and constipation, treated by Jogakhwanggeumdaehwang-tang(JHD-T). 2. JD-T in "Dongyisusebowon Gabogubon" was used for Yangdok and Onbyeong which are exogenous disease causing by heat. The composition of JD-T has been completed as it included Mahwang, Gilgyeong, and Seungma derived from prescriptions relevant with Yangdok. 3. JD-T in "Dongyisusebowon Sinchukbon(Sinchukbon)" was included in pathology of Ganyeol, and it substituted Galgeunhaegi-tang(GH-T) for Onbyeong, not for Yangdok, so Galgeun and Seungma became the main drug in JD-T. Galgeunseung-gitang(GS-T) was created for treating heat pattern owing to Daehwang, its main drug, and moreover Jogak's effect is too strong. Therefore, Mahwang, Hwanggeum and Gilgyeong was excluded from the composition of JD-T. 4. The origins of JD-T could be Yiseonggugo-hwan, Daesiho-tang, Jowiseungchung-tang, Heukno-hwan, and GH-T. The change of JD-T went for them throughout JHD-T to JD-T. JD-T in "Sinchukbon" consists of Galgeun and Daehwang which directly gets rid of severe heat from small intestine, and Jogak and Seungma which help to eliminate mild heat existing from small intestine throughout nose to flesh.
