Eoyakwonbang is a collection of prescriptions of Yuyaoyuan, an imperial medical bureau of China. While the first edition of this book does not exist at present, two versions printed in Korea, and one printed in Japan, which is the well-known Gyesasingan Eoyakwonbang have been passed down. Eoyakwonbang is a meaningful text for the history of medical communication between China, Japan and Korea, but research on the different versions and contents of Eoyakwonbang have been insufficient. Out of the 2 versions published in Korea, Eulheja Eoyakwonbang is different from Gapjinja Eoyakwonbang [another version in Korea] and Gwanjeong Eoyakwonbang of Japan, in that the prescriptions are organized, the ingredients are organized according to the amount of each ingredient for each formula, and the amounts are recorded in an accurate manner. On the other hand, the Gapjinja version has many mistakes in the characters and content. The Gwanjeong version has lesser mistakes in characters, but repeats the content error of the Gapjinja version. Eulheja was printed after correction based on the original version or unknown version from China. Gapjinja was re-printed based on the Gyesasingan version, while Gwanjeong seems to have used the Gapjinja version as its original script, as the mistakes made in the Gapjinja version are repeated in the Gwanjeong version as well.

Objectives : While the original version of 『Eoyakwonbang』 does not exist, its contents have been introduced in several studies. The existing editions are the Joseon versions 『SinganHyeminEoyakwonbang』(Eulhaeja edition) and 『GyesaSinganHyeminEoyakwonbang』(Gapjinja edition), and a Japanese version, 『GyesaSinganHyeminEoyakwonbang』(Gwanjeong edition). In a recent research, it has been discovered that there is a fourth edition of the book, 『SinganHyeminEoyakwonbang』(Jeonggadang edition), in the Japanese Parliament Library collection. Methods : Contents of the chapter on pediatric diseases were compared among the four editions to clarify their relation with each other. Results : Based on the organization of the chapter, formula names in the list and body, explanatory methods of the formulas, application, formula construction and methods of application, we found that there were great similarities between Eulhaeja edition and Jeonggadang edition, and between Gapjinja edition and Gwanjeong edition. Conclusions : 1. Jeonggadang edition is similar to Eulhaeja edition in contents and form. 2. Although the exact publication date of Jeonggadang edition is unknown, based on the fact that it was mostly circulated in the Qing period, it can be assumed to have been published after the Eulhaeja edition which was published in the 15th century. 3. Gapjinja edition was published in the 16th century and shares little similarity in form, organization and contents with Eulhaeja edition, indicating that a different version was used as the original script. 4. Gwanjeong edition was published in the 18th century, and is very similar in form, organization and contents with Gapjinja edition, repeating the same errors made in the Gapjinja edition. This indicate that Gapjinja edition was the mother script of Gwanjeong edition.
