Abstract
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.
