Evidence of the Cardioprotective Effects of in Isoproterenol-Induced Myocardial Infarction in Rats.

is a plant species that is widely used in Brazilian folk medicine for the treatment of different disorders that affect the cardiovascular system. The aim of the study was to investigate the cardioprotective effects of an ethanol-soluble fraction of (ESAP) on isoproterenol-induced myocardial infarction in rats. Different groups of rats ( = 8) were orally treated with ESAP (30, 100, and 300 mg/kg), carvedilol (10 mg/kg), or vehicle (filtered water; 1 mL/100 g) for 7 days.
