Abstract

Objective. A systematic review of randomized controlled trials has been performed to assess the effectiveness of stimulation of acupoint KI 1 by Artemisia vulgaris (the Japanese name is moxa) to lower blood pressure compared to antihypertensive drugs. Methods and Findings. Articles published from 1980 to August 2013 in databases of CENTRAL, Pubmed, CBM, CNKI, VIP, and online clinical trial registry websites were searched. Studies included were randomized controlled trials (RCTs); moxibustion-type intervention on KI 1 compared with antihypertensive drugs; meta-analysis showed superior effects of moxibustion plus antihypertensive drugs on systolic blood pressure (WMD: -4.91 [-7.54, -2.28]; P = 0.0003) but no superior effects on diastolic blood pressure (WMD: -6.38 [-17.17, 4.41]; P = 0.25). Conclusions. Our systematic review of the current literature shows a beneficial effect of using moxibustion interventions on KI 1 to lower blood pressure compared to antihypertensive drugs. However, the results are influenced by the existing differences in design of the current trials.
