The number of individuals with diabetes is increasing daily, and diabetes is presently estimated to affect about 422 million adults worldwide. Conventional drugs used to treat diabetes are not without severe side effects, accessibility, and affordability. This study elucidates the potential effects of (MO) leaves extract to manage and treat diabetes induced in male Wistar rats. Adult male Wistar rats were randomly divided into four groups ( = 12/group): NC - nondiabetic rats (positive control), MO - nondiabetic-treated rats, DM - diabetic rats (negative control), DM + MO - diabetic-treated rats. Hepatic enzymes and biochemical parameters as well as antioxidant capacity and inflammatory cytokine levels were assessed. Levels of low-density lipoprotein, high-density lipoprotein, and total cholesterol were evaluated. Oral administration of methanolic extract of MO (250 mg/kg) to diabetic rats for 42 days showed a significant reduction in hepatic enzyme markers and normalized lipid profile parameters in the serum compared to normal control group. Treatment also increased the level of antioxidant capacity and alleviated inflammatory biomarkers of the liver. Histology sections of the liver tissue showed protective effect of MO in treated rats. MO showed hepatoprotective, anti-inflammatory, and lipid-lowering effects against streptozotocin-induced hepatotoxicity. Histological section demonstrated specific alterations in the liver of the diabetic and nondiabetic male Wistar rats while MO treatment revealed improvement in liver alterations.
