Background: This study aimed to assess the toxicity of Irvingia gabonensis leaf extracts in albino rats and investigate their effects on body weight, liver function parameters, and renal function parameters. The research specifically compared the outcomes of aqueous and ethanol extraction methods. Methods: Acute toxicity was evaluated by administering a single oral dose of Irvingia gabonensis leaf extracts to rats and monitoring them for 24 hours and during a 14-day observation period. Sub-acute toxicity was assessed through a 28-day administration of the leaf extract. Body weight changes, liver function parameters, and renal function parameters were measured and compared among treatment groups. Results: No signs of toxicity or mortality were observed in rats treated with Irvingia gabonensis leaf extracts obtained through either aqueous or ethanol extraction methods. The calculated lethal dose required to cause mortality in 50% of the tested animals (LD50) exceeded 5000 mg/kg body weight. Oral administration of the leaf extract at doses of 400 and 800 mg/kg body weight did not induce any observable signs of toxicity or adverse effects during the 28-day study period. Male and female albino rats treated with the leaf extract showed significant weight gains compared to the control group. Higher doses (800 mg/kg) of both aqueous and ethanol extracts led to increased levels of total protein, albumin, and globulin in male albino rats, with the ethanol extract exhibiting a more pronounced effect. The administration of the ethanol extract, particularly at the lower dose (400 mg/kg), resulted in decreased levels of liver enzymes (AST, ALT, and ALP), suggesting potential liver protective properties. Additionally, bilirubin levels, a marker of liver dysfunction, were significantly reduced in all treatment groups, with the lowest levels observed in the groups receiving higher doses of both aqueous and ethanol extracts.
