Objective To observe the clinical effect of moxibustion therapy for 29 cases of yin-deficiency type acne.Methods In this clinical trial

56 cases of acne patients with yin-deficiency-inner heat type were enrolled.These patients were randomly divided into moxibustion group(treated by suspended moxibustion

n=29) and control group(treated by acupuncture

n=27).In addition

patients of the two groups were also treated by local purulent discharge and skin disinfection

once a week

4 times a month

8 times altogether.Both suspended moxibustion and acupuncture interventions were performed once every other day

3 times a week and 3 months altogether.The therapeutic effect was evaluated by skin lesion score and patients' constitution score.Results Of the patients in the moxibustion and control groups

2 and 1 was cured(the acne subsided above 90% and symptoms disappeared)

14 and 6 experienced marked improvement(the acne subsided by 60%-90% and symptoms were obviously relieved)

10 and 15 were effective(the acne subsided by 30%-59% and symptoms were relieved)

3 and 5 invalid(the acne subsided by below 30% and symptoms were worsen)

respectively.The effective rate of the moxibustion group was significantly higher than that of the control group(P<0.05).Following the treatment

the skin lesion score and yin-deficiency constitution score were significantly decreased in comparison with pre-treatment in the same one group(P<0.05)

and those of the moxibustion group were remarkably lower than those of the control group(P<0.05).Conclusion Suspended moxibustion is effective in improving both skin lesion and yin-deficiency constitution in acne patients with yin-deficiency-inner heat type.
