A pilot study carried out in Korea suggests that moxibustion can lower blood pressure in patients with hypertension. Forty-five subjects with prehypertension or stage I hypertension were randomised into three groups: moxibustion treatment group A (two sessions per week for four weeks), moxibustion treatment group B (three sessions per week for four weeks), and control group (no treatment). Eight standard acupuncture points (Guanyuan REN-4, Zhongwan REN-12, LI-11 Quchi, Zusanli ST-36 and Xuanzhong GB-39) were selected by specialists in acupuncture and moxibustion in a consensus process based on several previous studies. There were no significant differences in systolic blood pressure (SBP) or diastolic blood pressure (DBP) among the three groups after four weeks of treatment. However in treatment group B, there was a significant decrease in SBP and DBP from baseline to end of treatment. The author conclude that treatment frequency might affect effectiveness of moxibustion for blood pressure regulation.
