Objectives This paper investigates the origins, changes, and the constructive principles of Hyungbangjihwang-tang(荊防地黃湯).
Methods Hyungbangjihwang-tang and other related prescriptions were analyzed in terms of their pathological indications, based on previous literature including 『Gogeumuigam(古今醫鑑)』, 『Sanghannon(傷寒論)』, 『Uihagjeongjeon(醫學正傳)』, 『Donguisusebowon ⸱ Sasangchobongwon(東醫壽世保元 ⸱ 四象草本卷)』, 『Donguisusebowon ⸱ Gabobon(東醫壽世保元 ⸱ 甲午本)』, 『Donguisusebowon ⸱ Sinchukbon(東醫壽世保元 ⸱ 辛丑本)』.
Results and Conclusions The origins of Hyungbangjihwang-tang can be seen in three sections depending on the classification of medicinal herbs. Schizonepeta tenuifolia Briq.(荊芥), Saposhnikovia divaricata Schischk.(防風), Notopterygium incisum Ting(羌活), Aralia cordata Thunb.(獨活), and Plantago asiatica L.(車前子) originated from Hyungbangpaedok-san(荊防敗毒散) included in 『Gogeumuigam』. Poria cocos Wolf.(茯苓) and Alisma canaliculatum(澤瀉) originated from Ohryoung-san(五苓散) included in 『Sanghannon』. Rehmannia glutinosa for hueichingensis(熟地黃) and Cornus officinalis S. et Z.(⼭茱萸) originated from Yukmijihwang-tang(六味地黃湯) included in 『Uihagjeongjeon』.
Hyungbangpaedok-san was transformed into "Paedok-san" in 『Chobongwon(草本卷)』, Hyungbangpaedok-san in the 『Gabobon(甲午本)』 and 『Sinchukbon(辛丑本)』. Yukmijihwang-tang was mentioned as a Soyangin medicine in the 『Chobongwon』 and was later transformed into a Suhwagije-tang(水火旣濟湯) in 『Gabobon』. The meaning of Yukmijihwang-tang inherited in 『Sinchukbon』 as Dokhwaljihwang-tang and Hyungbangjihwang-tang. The medicinal herbs in Hyungbangjihwang-tang can be categorized in three sections by their functions, Schizonepeta tenuifolia Briq., Saposhnikovia divaricata Schischk., Notopterygium incisum Ting, Aralia cordata Thunb., and Plantago asiatica L. scatter the Pyohan(表寒) and make the Pyoeum(表陰) drop. Poria cocos Wolf.(茯苓) and Alisma canaliculatum(澤瀉) make the Pyoeum(表陰) drop through Lee-su(利水). Rehmannia glutinosa for hueichingensis(熟地黃) and Cornus officinalis S. et Z.(⼭茱萸) tonify Shin-won(腎元).
