Active ingredients of traditional Chinese medicine in the treatment of diabetes and diabetic complications

Mechanisms of TCM in treating DM are concluded: i) to promote insulin secretion and increase serum insulin levels; ii) to increase the sensitivity of insulin and improve its resistance; iii) to inhibit glucose absorption; iv) to affect glucose metabolism of insulin receptor; and v) to scavenge radicals and prevent lipid peroxidation. The separation and extraction of effective monomer from TCM is an important direction of anti-diabetic drug discovery currently. Future research about hypoglycemic mechanism of TCM based on the clinical should combine with modern scientific methods and regulatory approach to strive for more meaningful discovery and innovation.
