Abstract The adverse effect of Aflatoxin B1 (AFB 1 ) exposure in both humans and rodents has been widely reported. The beneficial health effects of gallic acid (GA) against AFB 1 ‐induced toxicity in vitro have been published. Here, we present in vivo findings on AFB 1 and GA on hepatorenal function in rats, exposed to AFB 1 (75 µg/kg body weight) only or co‐treated with GA (20 or 40 mg/kg) for 28 successive days. AFB 1 significantly increased pro‐inflammatory biomarkers and suppressed IL‐10 levels in rats’ liver and kidney. AFB 1 caused increased ( p < .05) oxidative stress by decreasing antioxidant enzymes levels and increasing levels of reactive oxygen and nitrogen species. Furthermore, reduction ( p < .05) in cellular glutathione (GSH) levels and increased ( p < .05) hepatorenal markers of toxicity were detected in rats treated with AFB 1 . These observed alterations were, however, reversed in GA co‐treated rats. GA ameliorated AFB 1 ‐induced hepatorenal dysfunction by decreasing oxidative stress and inflammation in rats. Practical applications GA can chemoprotect against the damaging effects of toxins contaminating food. GA is widely distributed in plants and in use in industries as antioxidant, immune‐regulator, and natural defense agent against infections when consumed. Here, we disclosed that GA ameliorates AFB 1 ‐induced hepatorenal dysfunction by suppressing oxidative stress, inflammation, and enhanced apoptosis, thus improving hepatorenal functions in rats exposed to AFB 1.
