This study aims to inspect the effects of green tea extract, A. absinthium extract, and mixture of them in diabetic rats. Forty adult male albino rats were divided into 5 experimental groups: The first group was considered as negative control group. The second group was positive control diabetic rats receiving normal diet with no treatment. The third group was diabetic rats receiving normal diet and receiving oral 50 ml of green tea extract, the fourth group was diabetic rats receiving normal diet and receiving oral 50 ml of A. absinthium extract. And the fives group was diabetic rats receiving normal diet and receiving oral 50 ml of green tea extract plus 50 ml of A. absinthium extract. The results showed decrease of serum glucose in groups (3, 4, and 5) but group No. 5 recorded the better reduction of blood glucose as compared with negative control. Treating diabetic groups fed on basal diet with different extract of green tea, A. absinthium led to a significant decrease in the mean value of serum cholesterol, triglyceride as compared to the positive control group. We can recommend that the extract of green tea plus A. absinthium has a hypoglycemic effect on alloxan-induced diabetes in rats
