Objectives : This study is aimed to search for the effective application of the Sa-Am acupuncture(舍岩鍼法) for the treatment of diarrhea. Methods : The classification and the treatment for diarrhea in ${ll}$Sa-Am-Do-In-Chim-Gu-Yo-Kyul(舍岩道人鍼灸要訣)${gg}$ was compared with those of ${ll}$Dong-Eui-Bo-Kham(東醫寶鑑)${gg}$ and ${ll}$Chim-Gu-Dae-Sung(鍼灸大成)${gg}$ Results & Conclusions : In ${ll}$Dong-Eui-Bo-Kham(東醫寶鑑)${gg}$, diarrhrea was classified into 20 classes and mainly treated with herbal medicine and additionally with acupuncture treatment. Ashi (nearby) points in lower abdomen and sacral region were often used as well as the points on Spleen meridian(SP) and Stomach meridian(ST) to treat diarrhea in ${ll}$Chim-Gu-Dae-Sung(鍼灸大成)${gg}$ According to ${ll}$Sa-Am-Do-In-Chim-Gu-Yo-Kyul(舍岩道人鍼灸要訣)${gg}$, Diarrhrea was classified into 6 classes; wet diarrhrea (濡泄; kidney damage), abrupt diarrhrea (暴泄; spleen damage), damp diarrhrea (濕泄; stomach damage), fire diarrhrea (火泄; heart dryness), ki(qi) diarrhrea (氣泄; lung damage) and cold diarrhrea (冷泄; liver damage). Sa-Am acupuncture seems to be applied on the basis of more precise diagnoses of organs and meridians and provide with more fundamental treatments in comparison with classical acupuncture.
