The mechanism of its effect in diabetes is that the fruit of Qaraqat inhibits glucose from the intestine to the blood, and the antioxidant present in this plant causes the level of triglycerides in the blood to decrease.

(AGEs) These substances are factors that can cause the development of diabetes and many other chronic diseases. Inhibition of AGE formation is a preventive and therapeutic goal for patients with diabetes, and a 2013 study showed that only olive leaf extract works as a natural diabetes treatment.

Olive leaf extract has a glucose-lowering effect, which means it lowers blood sugar levels. This extract also controls the blood glucose level in the body. Polyphenols present in olive leaf extract play a vital role in delaying the production of sugar that causes inflammatory diseases including diabetes.
