"약징(藥徵)"을 통해 본 길익동동(吉益東洞)의 의학사상 연구 III -길익동동의 의사관(醫師觀)과 의학관-

This study is on Yoshimasu Todo's thoughts of a real doctor and medicine. Conclusions are as below. disease-doctor[疾醫] is a doctor treating diseases by poisonous medicines. His role is different from food-doctor[食醫] who recuperates vital energy by food. Unlike food-doctor, a disease-doctor only detoxicates poisons of diseases by using poisonous medicines. Disease-doctor shall not take credit upon himself for the service of Heaven' s power. This is Yoshimasu Todo's view of a real doctor. Medicine is not an imagination, but a reality. It is the recognition of knowing what can be known and seeing what can be seen The truth of medicine is in ancient words(古語), ancient teachings[古訓] and ancient ways[古法]. To study medicine is not recklessly believing and following the contents of ancient medical texts-${\ulcorner}$Sanghanlon(傷寒論)${\lrcorner}$, ${\ulcorner}$Geumgwe-yolyag(金置要略)${\lrcorner}$,${\ulcorner}$Somun(素問)${\lrcorner}$, ${\ulcorner}$Yeongchu(靈樞)${\lrcorner}$. It is to follow the ancient ways written and left in ancient books and not to follow wrong ways fabricated by after ages. The theories of eum-yang-obaeng(陰陽五行) and o-un-yuggi(五運六氣) are useless to medicine because these are groudless ones. This is Yoshimasu Todo's view of medicine.
