Review Meta AnalysisNiuhuang Jiangya Preparation (a traditional Chinese patent medicine) for essential hypertension: A systematic review.
Niuhuang Jiangya Preparation (NHJYP) is one of the most commonly used traditional Chinese patent medicines for essential hypertension (EH) in China. Our meta-analysis performed a systematic evaluation on the therapeutic efficacy and safety of NHJYP for EH. ⋯ Our review indicated that NHJYP has some beneficial effects in EH patients with liver-yang hyperactivity and abundant phlegm-heat syndrome. However, the evidence is not reliable enough. To produce definite evidence, more rigorously designed trials are needed.
