Objectives : As there was no sufficient research done on Sasang (four harms: 氣[qi], 血[blood], 痰[phlegm], and 鬱[congestion]), which serves as a precept in treatment of miscellaneous diseases, in contrast with ‘Yang is always teeming whereas Yin is always scarce’ and ‘Sanghwa-ron’, which are Judangye’s major theories, I have come to work on it. I expect that with this, we can understand Judangye’s medical theory and therapy for a variety of diseases.
Methods : To begin with, I take a look at the definition of Sasang. And then, I make selections of theories and therapy related to Sasang from Gyeokchiyeoron(格致餘論) and Geumgweguhyeon(金匱鉤玄), which are Judangye’s writings. My study follows the order of energy, blood, phlegm, and congestion.
Results : Through Gyeokchiyeoron, I have learned more about Judangye’s theory on how energy, blood, phlegm, and congestion cause diseases. And as for therapy, I have tapped into Geumgweguhyeon to use sagunja-tang(四君子湯) for drained energy, samul-tang(四物湯) for drained blood, ijin-tang(二陳湯) for phlegm, and wolguk-hwan(越鞠丸) for congestion, thus verifying the originality of Judangye’s theory.
Conclusions : “Judangye for miscellaneous diseases” was confirmed through his treatments for energy, blood, phlegm, and congestion. And his idea of Yang-eum(養陰 ‘nurturing yin’) is now reflected in therapy for miscellaneous diseases, now serving as a study that provides a comprehensive understanding of Judangye’s medical theories.
