Abstract

Objectives : The objective of the study was to summarize randomized clinical trials(RCTs) that have assessed the effectiveness of herbal medicine on treatment of obesity and to propose better process of study. Methods : NLM Medline(pubmed), EMBASE, the Cochrane library, Science Direct, EBSCO, 4 Korean medical databases were systematically searched and 4 Korean medical journals were manually searched for clinical trials investigating the efficacy of herbal medicines on treatment of overweight or obese people from 1998 to 2008. The methodological quality was assessed using a Jadad score and validity was assessed using Oxford Pain Validity Scale(OPVS). Results : 14 RCTs met all the inclusion criteria. The methodological and ethical quality of the trials was generally low. The mean score by Jadad was 2.6 and the mean score of validity was 11.2. Complex herbal medicine was used in 8 RCTs and single herbal medicine was used in 6 RCTs. Except 1 RCT, the other RCTs reported positive effects of herbal medicine on treatment of obesity. Herbal medicines didn't seem to affect toxicity. In general adverse events relevant with the therapy were minor, but more than half of RCTs did not report about the safety or adverse events of herbal medicine, questioning their reliability. Conclusions : Although most RCTs concluded the efficacy and safety of herbal medicines on treatment of obesity, the quality of trials was low in general. Further rigorous clinical trials using complex herbal medicine should be performed.
