Tianma Gouteng Yin Formula for primary hypertension

Tianma Gouteng Yin Formula (TGYF) was reported to have a blood pressure lowering effect, improving clinical symptoms and quality of life in hypertensive patients. This review could not find any randomised controlled clinical trials that compared TGYF to placebo or no treatment. Further research to establish its efficacy is needed.

Authors' conclusions: 

As no trials could be identified, no conclusions can be made about the role of TGYF in the treatment of primary hypertension. Well-designed randomized controlled studies need to be conducted and published.
