Detailed Description:

Type 2 diabetes is health threats worldwide. However, treatment of this disease is limited by availability of effective medicines. All of the existing oral hypoglycemic agents have secondary failure after long term administration. Thus, new oral medicines are needed for long term control of blood glucose in patients with type 2 diabetes. In diabetes care, dietary approaches have drawn more and more attention in the prevention and treatment of hyperglycemia. Generally regarded as safe (GRAS) plants have been widely used for their benefits in antioxidation, anti-inflammation, anticancer, anti-obesity and anti-diabetes. Numerous botanical products such as pigments that include anthocyanins and flavonoids have been consumed or studied for anti-obesity and anti-diabetes. However, most of these botanical products are mixtures of multiple compounds. It is difficult to control their quality in the study or production. Up to now, as a single purified compound, berberine is demonstrated to have hypoglycemic effect in vitro and in vivo. Berberine is the main active component of Coptis chinensis French, which was used for thousands of years in China in the treatment of human diseases including diabetes.

Comparison(s): Effects of berberine compared with metformin in newly diagnosed type 2 diabetic patients.
