The potential role of saffron (Crocus Sativus L.) and its components in oxidative stress in diabetes mellitus: A systematic review

خلاصه انگلیسی

Background and aims Diabetes mellitus is one of the most important life-threatening metabolic diseases of the 21st century. The use of complementary and alternative medicine in diabetic patients seems to be increasing. Saffron, a valuable herbal medicine, has several pharmacological properties such as anti-oxidant effect, which can play important role in ameliorating the complications of diabetes. The aim of this study was to systematically review the therapeutic effects of saffron and its bioactive components on oxidative stress in diabetes mellitus. Methods In this systematic review, databases such as PubMed, SCOPUS, Embase, ProQuest, and Web of Sciences were searched from the beginning to December 2021. All eligible in vitro, animal, and human studies that examined the effect of saffron on oxidative stress indices in diabetes were prepared in the form of a full article in English. Results In the end, only 31of the 389 articles met the criteria for analysis. Of the 31 articles, 4 were in-vitro studies, 25 were animal studies, and 2 were clinical trials studies. Saffron supplementation may activate insulin receptor substrate 1 (IRS1) and peroxisome proliferator-activated receptor gamma (PPAR-γ), which can improve hyperglycemia and insulin transduction signal in adipose tissue, and regulate glucose metabolism, leading to an increased nuclear factor erythroid 2–related factor 2 (Nrf2), HO-1 expression, amelioration of mitochondrial function, and an increased levels of antioxidant enzymes. Conclusion Most studies have shown that saffron supplementation significantly enhanced the production and activity of antioxidant enzymes and decreased oxidative stress indices in diabetes mellitus. However, human pharmacokinetic and more accurate clinical trial studies are needed to determine dose ranges and the exact mechanisms of action of saffron and its active components in diabetes.
