Abstract

Aim: Considering traditional use of Tribulus terrestris in diabetes and proven antihyperglycemic and antihyperlipidemic effects of T terrestris in animal studies, we aimed to evaluate the efficacy of the hydroalcoholic extract of T terrestris on the serum glucose and lipid profile of women with non-insulin-dependent diabetes mellitus.

Methods: Ninety-eight women with diabetes mellitus type 2 were randomly allocated to receive the T terrestris (1000 mg/d) or placebo for 3 months. The patients were evaluated in terms of the fasting blood glucose, 2-hour postprandial glucose, glycosylated hemoglobin, and lipid profile.

Results: Tribulus terrestris showed a significant blood glucose-lowering effect in diabetic women compared to placebo (P < .05). Also, the total cholesterol and low-density lipoprotein of T terrestris group was significantly reduced compared with placebo, while no significant effect was observed in the triglyceride and high-density lipoprotein levels.

Conclusions: The study showed preliminary promising hypoglycemic effect of T terrestris in women with diabetes mellitus type 2.

Keywords: Tribulus terrestris; diabetes mellitus; herbal medicine; traditional medicine.
