Historical study of 濟衆入效方 -focusing on 交效散

"濟衆立效方" is the oldest Koryo dynasty medical document known to date. Despite its historical importance, due to the absence of its original copy, its true characters could not be understood. Through comparison of the many documents that cited 濟衆立效方, it could be found that 濟衆立效方 can be classified into two parts based on its contents and form. In Chinese medical texts, neither the name 交效散 nor any similar prescription is mentioned. 濟衆立效方 was the first in suggesting the usage of pine needles and salt for fomentation and not for internal use. Thus 交效散 can be thought of as the oldest indigenous prescription preserved in Korean history. 濟衆立效方 conveys records of the combination of the ancient origin pine needle fomentation and the creative addition of salt.
