Objectives: The purpose of this study is to review the recent clinical study trends on Korean Medicine treatment for vaginitis during pregnancy. Methods: We searched articles published from electric databases including Oasis, KISS, Pubmed, and CNKI. The period was set from 2012 to 2021. Searched keywords were “임신 중 질염”, “한약”, “Vaginitis during pregnancy", “Herbal medicine", “妊娠合并阴道炎", “中药”. Results: 34 articles were finally selected. Except 1 case series study, there were 33 RCTs, 1 article of which used both herbal decoction and herbal fumigation for treatment group (TG) ; 18 employed herbal fumigation only, and 14 took both herbal fumigation and western medicine. The total effective rate or cure rate in TGs, regardless of treatment methods, was higher than that of control group in all RCT studies. Conclusions: Our review found that Korean medicine alone or combined with western medicine is more effective for alleviating symptoms of vaginitis during pregnancy than the control group.
