The auricular therapy included in this systematic review was in diverse forms. Bloodletting in the auricle had better immediate effects than no intervention on both efficacy rate and lowering of BP and bloodletting in the auricle plus ADs showed a favorable difference in efficacy rate compared with ADs alone, while there was no statistical difference between bloodletting in the auricle and ADs in terms of efficacy rate. It is worth mentioning that the safety of bloodletting in the auricle should draw our attention, as it is a kind of traumatic intervention, despite the fact that such therapy has been applied in China for a long period of time.
