Background: Almost all Xylopia species have a long history of being used therapeutically in China due to their potent antioxidant properties. Xylopia parviflora (X. parviflora) is a relatively novel plant comprised mainly of beta-pinene, which has a rich history in Chinese medicine and is a principal active constituent in numerous Chinese herbs such as Rakkyo, the Chinese onions, Huasi Baidu Fang and Ru Xiang which are all native to China. Objective: The study evaluated the antidiabetic potentials of the methanol leaf extract of X. parviflora and its toxicity profile. Methods: A modified version of the OECD guidelines was used to conduct acute and sub-chronic toxicity tests on the plant extract. The extract's effects on glucose, haematological, and biochemical components were evaluated using standard procedures. Using glibenclamide (10 mg/kg) and distilled water as positive and negative controls, the extract was tested for its antidiabetic activity in diabetic rats with streptozotocin induction at 50, 150, and 300 mg/kg for 28 days. Furthermore, vital organs underwent histopathological examination. Analysis of Variance (ANOVA) and the Dunnett multiple comparison tests were used for the statistical analysis, with a significance level of p
