Diabetes mellitus is one of the most common and widespread metabolic illnesses worldwide. Hyperglycemia is a symptom of this
condition, which is caused by problems with insulin secretion, insulin action, or both. Various medicinal plant species are used as a
traditional treatment for diabetes mellitus, such as green tea, which is one of these plants whose extract has been used to treat
diabetic patients for many years. The goal of this study was to see if green tea had any antioxidant benefits on the pancreas of
alloxan-induced diabetic male albino rats. This experiment involved albino rats weighing between 110 and 120 grams. Three groups
of animals were created. Control untreated normal healthy group, Alloxan-induced diabetic group and diabetic group treated with
green tea. Tissue samples from diabetic and treated rats were collected and pathologically evaluated to determine the degradation
of pancreatic cells in diabetic rats. In diabetic rats, biochemical data revealed a significant decrease in serum insulin, body weight,
and total proteins when compared to the control group. Most of these measures improved significantly when diabetes rates were
managed daily with green tea. In comparison to the control group, there was a significant improvement in morphological changes
in diabetic groups after treatment with green tea in pancreatic tissues. Green tea, it may be concluded, can be used as an antidiabetic drug to lower blood glucose levels and protect against the harmful consequences of diabetes.
