Abstract

Diabetes mellitus is a chronic metabolic disorder that is of worldwide concern. It results in several complications such as high blood pressure, neuropathy, glaucoma, kidney damage and feet ulcers. There are principally two types of diabetes that affect humans: Type 1 and Type 2. Several drugs have developed over the years to combat or controlled diabetes. However, the side effects that they produced, along with the cost of synthesis and environmental issues, there is a need to resort to plant based anti-diabetic agents. Research have been increasing in this direction. Plant based anti-diabetic agents are superior because they are cheaper and environmentally safe. However, if they are to replace synthetic analogues, their anti-diabetic potency must be comparable to synthetic analogue such as metformin and glibenclamide.
