Curcumin, a natural compound present in turmeric, has anti-inflammatory and antioxidant properties that aid in controlling diabetes. Curcumin can lower blood glucose levels, increase pancreatic cell function, and reduce insulin resistance. The pathophysiology of diabetes involves oxidative stress and endoplasmic reticulum stress, which can lead to cell death. This study aimed to evaluate the antidiabetic activity of curcumin in rats by administering it for a month and evaluating pancreatic tissue histology.Patients and Methods: STZ-induced diabetic rats were fed a high-fat diet containing glibenclamide, 200 mg/kg body weight (BW) curcumin, 400 mg/kg BW curcumin, or a placebo for 4 weeks. After intervention, blood glucose levels were measured, and the pancreatic tissue was examined. Blood glucose levels were measured at 0, 2, 4, 6, and 8 h.Results: One-way ANOVA was performed to measure the mean difference among the groups at 0, 2, 4, 6, and 8 h of observation, which reported a statistically significant difference (p < 0.05). The blood glucose levels decreased after 4 h in the group receiving curcumin. Histological evaluation of the pancreas showed slight hydropic degeneration after 4 weeks of curcumin treatment.Conclusion: Our study indicates that curcumin has a beneficial effect in diabetic rats by reducing blood glucose levels and a protective effect on the pancreas.Keywords: curcumin, diabetes, blood glucose, antidiabetic, antioxidant, insulin resistance
