Protective effects of plant-derived natural products on renal complications.

Diabetic nephropathy is the leading cause of renal failure worldwide. This debilitating disorder has several underlying pathophysiologic mechanisms, and therefore a variety of pharmacologic agents have been developed to prevent or treat diabetic nephropathy; however, synthetic drugs may possess unfavorable side effects. In response to this, the global use of herbal-based pharmacologic agents is increasing among diabetic patients. Numerous studies have reported therapeutic benefits of herbal-based compounds against diabetes-induced renal dysfunction. These agents can prevent renal dysfunction and improve renal function by blocking or suppressing deleterious pathways such as oxidative stress, inflammation, apoptosis, necrosis, and nitric oxide deprivation that lead to vascular injuries. In the current study, we have reviewed the beneficial properties of the most common herbal agents used in renal complications and diabetic nephropathy.
