Objectives : The aim of this study is to review papers on adverse events in the course of Oriental Medical treatments in the JKAMS and the JCTKAM. Methods : We searched papers up to December 2010 in the JKAMS and The JCTKAM. Electronic and manual literature searches were performed. Results : 92 papers were retrived in total. Out of these, 62 reported the occurrence of adverse events whereas 30 reported none. Adverse events in treatments were generally transient and mild. However, this result had limitations due to the insufficient number of papers reporting adverse events and the inconsistency in the methodology according to each paper. Conclusions : Reports on adverse events are necessary in clinical research. In future research, organized case reports and systemic reviews should be carried out. Furthermore, prospective studies should be done as well.
