This study evaluated liver function of diabetic rat treated with ethanol extract of Chrysophyllum albidum stem back. Diabetes was induced intraperitoneally in the rat with streptozotocin [STZ, 40mg/kg body weight (bwt)], and rats with fasting blood glucose levels exceeding 200 mg/dL were considered diabetic. Animals were treated with 200 mg/kg bwt ethanol extract of C. albidum stem bark or 50 mg/kg bwt metformin for 14 days, with a diabetic control group receiving no treatment. Fasting blood glucose levels were monitored using an Accu-check glucometer before and during treatment. Blood sample collected after euthenization were used for biochemical analysis. Results showed a significant reduction in blood glucose level in metformin group compared to Ethanol extract of C.albidum (p < 0.05). Activities of Alanine aminotransferase (ALT), Aspartate aminotransferase (AST) and Alkaline phosphatase (ALP) in the plasma shown no significant increase when compared to control (p>0.05). Similarly, Albumin and Bilirubin concentration show no significant increase (p>0.05). These findings suggest that ethanol extract of C. albidum stem bark particularly at 200 mg/kg bwt, exerts significant ethnomedicinal effect on diabetic rat liver.

Acanthus montanus, commonly referred to as "beer's breech," "alligator plant," or "mountain thistle," is a potent medicinal plant that belongs to the Acanthaceae family. It holds significant importance in ethnomedicine. Throughout Nigeria's history, it has been utilized for managing a diverse array of health issues including wounds, gonorrhea, heart failure, and more. Acanthus montanus is rich in phytochemicals, including alkaloids, saponins, flavonoids, tannins, glycosides, and terpenoids. These compounds exhibit diverse biological and pharmacological properties, encompassing analgesic, anti-inflammatory, immunological, anti-fertility, antidiabetic, hepatoprotective, and hepatocurative activities. This study investigated the reproductive toxicological effects of aqueous leaf extracts of Acanthus montanus on male and female Wistar rats. Extracts were administered at varying doses (200 mg/kg, 400 mg/kg, and 800 mg/kg) and 0.5 ml of distilled water as control. The body and organ weights (testes, penis, uterus, ovaries) demonstrated no significant deviations from the control group. Toxicological assessments revealed no adverse impacts on lipid metabolism, as evidenced by lipid profile assays. Hormonal analyses affirmed that the extracts maintained endocrine equilibrium, with hormone levels within normal ranges in all make treated groups, while the female groups exhibited varying level of fluctuations in their hormonal levels. Antioxidant assays disclosed noteworthy antioxidant effects, particularly at the highest dose (800 mg/kg), reflecting the potential of Acanthus montanus extracts to combat free radicals and uphold cellular integrity. Histological evaluation of reproductive organs unveiled no notable structural changes, indicating the extracts' non-induction of tissue damage or morphological aberrations. In conclusion, aqueous leaf extracts of Acanthus montanus, across various dosages, exhibited negligible impact on body and organ weights, reflecting safety. Moreover, they displayed antioxidant properties without compromising reproductive health or lipid metabolism. This underlines the promising prospects of Acanthus montanus extracts as natural antioxidants in the realms of reproductive health and oxidative stress management. While these findings are encouraging, further research across diverse animal models and potentially human subjects is imperative for a comprehensive understanding of the plant's benefits and mechanisms
