Introduction: Moxibustion is the burning of mugwort used to stimulate acupuncture points on the skin. In traditional East-Asian medicine, moxibustion is often used as a non-drug treatment for idiopathic Parkinson’s disease (IPD). The aim of this systematic review was to evaluate the effectiveness and safety of moxibustion therapy to treat IPD.

Methods: The following electronic databases were searched for studies published in or before December 2016: Medline, the Cochrane Central Register of Controlled Trials (CENTRAL), EMBASE, OASIS (Korean database), and CNKI (Chinese database). Two researchers conducted the data extraction and risk of bias assessments.

Results: From the results, a total of 10 studies (644 IPD patients) were included in this review. Overall methodological quality was not high and all studies included small numbers of participants which could not ensure the rigor of the synthesized evidence. There was a considerable clinical heterogeneity in terms of patient’s population, moxibustion types and control group interventions. Compared with control group, moxibustion did not show significant difference in the overall effectiveness ratio (RR 1.20, 95% CI [1.00, 1.44]). About the total unified Parkinson’s disease rating scale (UPDRS) score, however, there was significant difference between moxibustion and control interventions (MD -8.75, 95% CI [-12.54, -4.95]). Adverse events related to moxibustion treatment were not reported in most of the studies.

Conclusions: Evidence on the benefit and harm of moxibustion therapy for IPD was not conclusive due to methodological problems and small sample sizes among the included studies. More rigorous clinical studies will be necessary in future.
