Objectives : The Gyotae-hwan formula has traditionally been applied to conditions of fearful throbbing[怔忡] and insomnia due to disharmony of the Heart and Kidney, of which experimental and clinical research has been carried out while those on its pathological mechanism and constituent compatibility have been inadequate. Methods : Pathological mechanism and constituent compatibility of the Gyotae-hwan formula as listed in the 『Comprehensive Medicine According to Master Han』(韓氏醫通) and the『Simple Recipes for Four Disciplines』(四科簡效方) were analyzed. Findings from recent researches searched using the keywords '交泰丸' and '교태환' in the OASIS and CNKI databases were referenced as well. Results : The Gyo-tae hwan was first mentioned in the text 『Comprehensive Medicine According to Master Han』by Mao Han in terms of constituent medicinals and application while measurements and name of formula were not listed while the concept of harmony between the Heart and Kidney was mentioned. In the『Simple Recipes for Four Discipline s』 written by Shixiong Wang, measurements of constituent medicinals, usages and name of formula were finally mentioned, along with its efficacy to treat fearful throbbing and insomnia due to disharmony between the Heart and the Kidney. Conclusions : In conclusion, the Gyo-tae hwan uses Coptidis Rhizoma as chief herb and Cinnamomi Cortex as assistant herb to change the state of disharmony between the Heart and Kidney to a harmonious state, treating insomnia and fearful throbbing.
