The median methodological quality score was 2 out of a possible maximum 5. The effectiveness of herbal medicines for treating chronic obstructive pulmonary disease is not established beyond reasonable doubt. Currently, the evidence from randomised clinical trials is scarce and often methodologically weak. Considering the popularity of herbal medicine among chronic obstructive pulmonary disease patients, rigorously designed studies seem warranted. %U //www.qdcxjkg.com/content/erj/28/2/330.full.pdf
