Although many clinical studies have been conducted to investigate the effectiveness of auricular therapy for treating hypertension, these studies have not yet been systematically summarized and the overall evidence is still uncertain. Herein, it is worthwhile to evaluate the evidence for the effectiveness and safety of auricular therapy for hypertension with a systematic review and to provide recommendations on future research and practice in this field.
