This study evaluated the toxicological effects of Guiera senegalensis on wistar rats. Method: An acute toxicity was carried out to determine the LD50 of Guiera senegalensis stem bark extract. Sub-acute toxicity was carried out to determine the effect of the plant extract on some liver and kidney function parameters and haematological parameters. Twenty (20) rats were ramdomly placed into 4 groups of 5 rats. Group 2, 3 and 4 were orally treated with aqueous stem bark extract of Guiera senegalensis at a daily dose of 200, 400 and 800 mg/kg body weight (b.wt.) respectively for 28 days while group 1 served as a control group. Results: ALT, AST, ALP and bilirubin levels increased significantly as dose increases. No significant increase in K+ and urea was observed in group 2 and 3 treated with 200 mg/kg and 400 mg/kg respectively. However, significant increase was observed in group 4 treated with 800 mg/kg. Na+ and Creatinine showed significant increase when compared with control group. RBC, PCV, and Hb decreased significantly whereas a significant increase was observed in WBC with increase in dose respectively. Conclusion: The aqueous stem bark extract of Guiera senegalensis have a dose-dependent toxic effect on liver, kidney and haematology of wistar rats.Key words: Toxicological Evaluation, Guiera Senegalensis, Liver, Kidney, Haematological parametersen10.53811/ijtcmr.1060996info:eu-repo/semantics/openAccessToxicological EvaluationGuiera SenegalensisLiverKidneyHaematological parametersTraditional, Complementary and Integrative MedicineArticle314551DergiPark: 1060996
