The hydroalcoholic extract of the fruit of Vaccinium floribundum HBK "pushgay" was tested in Rattus rattus variety albinus to determine its hepatoprotective effect against oxidative stress induced by carbon tetrachloride. We worked with 20 rats divided into four groups: negative control, which was inoculated for seven days via orogastric tube, sterile physiological saline (SSFE); positive control, which was inoculated two days via orogastric tube, carbon tetrachloride 1 mL·Kg-1 body weight and then by five consecutive days SSFE and experimental, consisting of two groups, which were inoculated, via orogastric tube, carbon tetrachloride 1mL·Kg-1 body weight for two days and then for five consecutive days, the hydroalcoholic extract of Vaccinium floribundum at concentrations of 300 mg·Kg-1 body weight and 600 mg·Kg-1 body weight each group respectively. The concentration of free radical...
