Tangerine peel in Qili Qiangxin capsule was found to mitigate pathological myocardial hypertrophy induced by AngII and chronic HF induced by isoproterenol (ISO) through upregulation of PPAR-γ, while also reducing pathological myocardial remodeling via activation of PPAR-γ. This evidence concerns the gene PPARG and hydrops fetalis.
