Abstract
Numerous remedies recently consumed in health system are obtained from natural plants. For instance metformin, one of the prevalent drugs for controlling diabetes mellitus with hypoglycemic activity, is derived from the plant, Galega officinalis. Type 2 diabetes mellitus is a frequent metabolic disorder characterized by persistent hyperglycemia. High blood sugar may give difficulties like renal and cardiovascular disorders, retinopathy, and poor blood flow for long-term. Its advance can be prohibited in patients with spoiled glucose tolerance by implementing lifestyle changes or the use of helpful agents such as medicinal herbs administered for many years because the presence of antioxidants like flavonoids in them can have a protective influence on various renal diseases and diabetic complications but since using of herbal medicine and also treatment of frequent chronic diseases such as diabetes mellitus, need a programmed management, so prevention and therapeutic process should be considered by healthcare system and also there is a need to develop a basis for standardization that ties the composition of herbs to efficacy. In absence of such standardization, the use of herbs in diabetes must be approached cautiously.
