Project description:Kangxian formula (KXF), composed of 5 traditional Chinese distinct herbs including Panax Notoginseng, Radix Salviae, Spatholobus Suberectus Dunn, Hedysarum Multijugum Maxim and Citri Grandis Exocarpium, is a proved recipe showing promising outcomes in treating hypertension and cardiac remodeling in clinic. However, the effect of longterm treatment with KXF in such a condition and the related molecular mechanisms remain ambiguous. Here, we evaluated the effect of KXF on the gut microbiota and the prevention of hypertension and cardiac remodeling.
