BACKGROUND: Okbyungpoongsan (OBPS) is widely used as a treatment for allergic rhinitis (AR) in Far East countries. Many clinical trials have assessed the efficacy and safety of the OBPS formula for treating AR. Here, we systematically will review the clinical evidence for and against administration of OBPS.

METHODS AND ANALYSIS: All RCTs of decoctions or modified decoctions will be included. The methodological quality of the RCTs will be analyzed using the Cochrane Collaboration tool for assessing risk of bias, while confidence in the cumulative evidence will be evaluated using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) instrument.

ETHICS AND DISSEMINATION: This systematic review will be published in a peer-reviewed journal and will also be disseminated electronically and in print. The review will be updated to provide additional information and guide healthcare practices.Registration number: CRD42017080292.
