Objectives: To evaluate hypoglycemic effect of Giang chi tieu khat linh (GCTKL) capsule in experimental diabetic-induced white rats with dyslipidemia. Methods: Described in experiment, 42 white rats were divided into 6 groups to drink GCTKL (test group) or NaCl 9 thousandths (controls), compared the results between the test and control groups at the Vietnam-Sweden Hospital, Uong Bi, Quang Ninh, from August 2011 to June 2012. Results: Rats with dyslipidemia and streptozotocin-induced diabetic, which were taken GCTKL at dose 840 mgjkg & 1260 mgjkg via oral, had the blood glucose level reduction after 2 hours and reached the lowest point between 4-6 hours. The blood glucose level increased again at hours 10 and 12. For healthy rats, the blood glucose level with the same dose of GCTKL remained unchanged. Conclusions: GCTKL has hypoglycemic effect in experimental diabetic-induced white rat.
