Discussion on the similarities and differences between YE Gui and ZHANG Ji in the treatment of thoracic obstruction heartache
ZHANG Ji a famous medical expert in the late Eastern Han Dynasty,once had a systematic discussion on thoracic obstruction heartache in the Jingui Yaolue(《金匮要略》).YE Gui,a famous medical expert in Qing dynasty,studied ZHANG Ji's theory.On the basis of inheriting ZHANG Ji's theory and combining his own clinical experience,YE Gui had his own unique views on the treatment of thoracic obstruction heartache.Both YE Gui and ZHANG Ji believed that insufficient Yang(阳)in upper-Jiao(上焦)and excessive Yin(阴)in lower-Jiao(下焦)was the pathogenesis of chest pain.It means that Yang Qi(阳 气)in the chest is weak,which cannot warm and nourish the viscera.The viscera function is abnormal,causing Qi stagnation,blood stasis,phlegm coagulation and other Yin pathogens,which disturb the heart and cause thoracic obstruction heartache.Both of them used pungent medicines when selecting prescriptions.Pungent medicine has the effects of dispersing,and promoting Qi(气)and blood circulation.It can warm the chest Yang,promote Qi and blood circulation,resolve phlegm,and stop thoracic obstruction.ZHANG Ji focused on the middle and upper energizer in identifying the location of the disease,and commonly used heart and lung related prescriptions such as the Gualou Xiebai Baijiu decoction(瓜蒌薤白白酒汤)and the Gualou Xiebai Banxia decoction(瓜蒌薤白半夏汤),etc..YE Gui focused on the triple energizers,often used the Gualou Xiebai Baijiu decoction and the Gualou Taoren prescription(瓜蒌桃仁方)for upper energizer medical cases,the Xiao Banxia decoction(小半夏汤)and the Banxia Ganjiang prescription(半夏干姜方)for middle energizer medical cases,and the Linggui Weigan decoction(苓桂味甘汤)and the Shengdi Ejiao prescription(生地阿胶方)for lower energizer medical cases.In the treatment of severe thoracic obstruction heartache,the two experts used different prescriptions due to different living areas.In history,ZHANG Ji lived in the north of the Changjiang River.People in the north were fat and strong,and their Qi was deep and thick,so ZHANG Ji used very pungent and hot prescriptions to treat severe cases.YE Gui lived in the south of the Changjiang River.People in the south were mostly thin and weak,and their Qi was floating and thin.YE Gui used the slightly pungent and sweet prescriptions to treat severe cases.There are similarities and differences between the two experts in the treatment of thoracic obstruction heartache.This paper makes a comprehensive analysis of the two theories in order to learn from each other's strengths for clinical reference.
