Abstract
Aim: The objective of this study was to assess the protective and curative potential of ethanol leaf extract of Corchorus olitorius against potassium bromate (KBrO3)-induced renal toxicity.
 Methodology: Corchorus olitorius was extracted using a soxhlet extractor and ethanol as the solvent. After becoming accustomed to the lab, 24 mature male Wistar rats were randomly assigned to groups A, B, C, and D. Group A received oral distilled water as treatment. Animals in groups B, C, and D got 100 mg/kg body weight of potassium bromate while groups C and D also received 100 and 200 mg/kg body weight of Corchorus olitorius respectively. Fresh potassium bromate and groups C and D extract were administered to rats every day by oral gavage. After taking the drug for the recommended 28 days, blood and kidney samples were collected. Renal biomarkers were evaluated using conventional methods.
 Results: Significant (P0.05) increase in the serum concentrations of creatinine, urea, uric acid, sodium (Na+), potassium (K+), chloride (Cl–), and bicarbonate (HCO3–) were observed following potassium bromate administration in comparison to the control group. KBrO3 poisoning also increased the levels of the inflammatory proteins interleukin-6 (IL-6) and tumour necrosis factor-alpha (TNF-) in the kidneys compared to the control group. Yet when KBrO3 and C. olitorius leaf extract were administered together, levels of all kidney indicators were significantly reduced in a dosage-dependent manner, with 200 mg/kg being the most efficient dose.
 Conclusion: This study found that C. olitorius leaf extract, particularly at the higher dose of 200 mg/kg, was successful in reducing a number of the parameters examined that had been negatively impacted by KBrO3. It may be advantageous to include C. olitorius leaf in edible products that may contain KBrO3, such as flour, bread, or cakes, as it is a well-known dietary prebiotic with established safety profiles in humans. Further research is required to determine whether C. olitorius leaves can reduce the toxicity of KBrO3 in human organs and other animal strains, as well as perhaps treat it.
