Herbal medicine (Gegen-decoction) for treating cervical spondylosis: A systematic review and meta-analysis of randomized controlled trials

GGD may be effective in reducing symptoms of patients with cervical spondylotic radiculopathy. However, this study found that there is insufficient evidence supporting the effect of GGD for cervical spondylosis. Therefore, rigorously designed and placebo-controlled trials of GGD should be conducted to provide such evidence.
