The toxicological potential of the ethanolic extract from Campomanesia guazumifolia (EECG), a species traditionally recognised for its antidiabetic, anti-inflammatory and hypercholesterolemic properties, was investigated in acute and subacute toxicity models in rats. In the acute toxicity test, 2000 mg/kg of EECG was administered orally in female rats, while male and female rats received 250, 500 or 750 mg/kg of EECG for the subacute toxicity test. No evidence of toxicity was observed in the animals acutely exposed, indicating that the LD50 is above 2000 mg/kg. However, repeated exposure to this extract resulted in alterations in important biochemical parameters indicative of hepatic and renal toxicity, including AST, ALT, creatinine, urea, and cholesterol. Additionally, some hematological parameters were also changed by the treatment. EECG demonstrated low toxicological potential. Nevertheless, given the observed changes in liver and kidney enzymes, further investigations into the protective effects of this extract following repeated administration are warranted.
