Objectives : Nomenclature for medical terminology is the most important point in traditional medical standardization. For example, standard nomenclature for acupuncture points, herbal medicines and prescriptions have been treated. However, studies on standard nomenclature for traditional medical books are rare. Methods : Following up all articles in Journal of Korean Medical Classics[JKMC], which have romanized name for medical books and analyzing problems of those. Results : There were so several methods to write in romanized character even to unique and replaceable name. Conclusions : Romanized nomenclature for medical book as a terminology must have unique expression. So we suggest that authors to write articles have to use unique romanized nomenclature for medical books and books published in a certain country should be written in romanized characters with their own languages.
