To conduct a review of the systematic reviews and meta-analyses on the Traditional Chinese Medicine (TCM) treatment of type 2 diabetes mellitus (T2DM). ⋯ This work shows favorable evidence for the clinical treatment of TCM on T2DM. However, it is recommended that evidence-based decisions are made based on clinical trials because of the GRADE scores of the studies. To achieve higher quality of clinical research, clinical research on TCM requires specific and suitable research methods. Further trials may increase the quality of evidence to evaluate the clinical efficacy of TCM for T2DM.
