Overview

The incidence rate of type 2 diabetes in Thai populations is high and increasing every year. Cardiovascular disease is the main complication of this disease, which has been defined as an important cause of death among Diabetic patients. This disease is now becoming a major health problem and causes a great economic loss to the country. Evidence shows that Curcumin, Thai herbal medicine, has the effectiveness of prevention and delay of type 2 diabetes. However, there is no scientific study that aims to prove the efficacy of this herb particularly for prevention and delay the disease in Patients with impaired glucose tolerance (pre-diabetes) and insulin resistance.
