This study aimed to elucidate changes in clinical practice by comparing the formulas used then and now. Methods: All formulas described in Yoyokasoku (In‐house Methods of Pediatrics [IMP], a Kampo classic published in 1885) and formulas used in a contemporary pediatric Kampo guideline were extracted. Then, a database with annotations to formulas was compiled. Results: In all, 387 formulas (274 excluding duplications) and 10 methods of moxibustion/surgical treatments were extracted from IMP. The total number of classical formulas described was 72. The proportion of classical formulas was significantly different among disease clusters (P < 0.0001). Overall, the contemporary Kampo guideline used classical formulas in any type of disease, and the proportion of this usage was significantly higher than that in IMP (59% vs. 19%, P < 0.0001). IMP described 95 Japanese original formulas (25%) including 45 in‐house formulas. However, none of them have been implemented in the contemporary guideline. Conclusion: Current Kampo pediatrics may have developed less under the influence of a pediatric classic in the nineteenth century; however, a thorough investigation of pediatric books is needed to understand the history of Kampo pediatrics., Version of Record online: 02 November 2020 ファイル公開:2021-11-02}, pages = {100--105}, title = {Comparison of the formulas from the current form of traditional Japanese pediatrics and those described in Yoyokasoku (in‐house methods of pediatrics): A representative pediatric classic}, volume = {8}, year = {2021} }
