Objectives: The purpose of this study is to review clinical studies related to the effect of Traditional Chinese Medicine (TCM) on moderate to severe obese patients with hypertension. Methods: Clinical studies from the China National Knowledge Infrastructure (CNKI) were searched by specific keywords and criteria. Total of 7 randomized controlled trials were selected and analyzed. Results: Various evaluation methods were used to see the effect of TCM compared to conventional western medicine. Most of the studies used herbal medicine combined with conventional anti-hypertensive western medicine. The effective rate of anti-hypertension was higher when TCM was added to conventional anti-hypertensive medicine. Traditional medicine treatment showed significant effect on lowering blood pressure and body mass index. Conclusions: Based on the results of the clinical studies from China, TCM can be a valuable option for moderate to severe obese patients with hypertension. Applying Traditional medicine has a significant effect on lowering blood pressure and weight loss. Combining herbal medicine can be worthy of clinical promotion and application for moderate and severe obese patients with hypertension.
