Abstract: Background: The activation of oxidative stress and inflammatory conditions has been
associated with acceleration in diabetes (DM) onset and complications. Despite various anti-DM
medications, there is a growing trend to discover inexpensive and effective treatments with low adverse
effects from plants as one of the promising sources for drug development.
Objective: This study aimed to systematically investigate the simultaneous anti-inflammatory and
antioxidant effects of plant-derived hypoglycemic medicines in diabetic experimental models.
Methods: The search terms consisted of “diabetes”, “herbal medicine”, “antioxidant”, “Inflammatory
biomarker”, and their equivalents among PubMed, Scopus, Web of Science, and Cochrane Library
databases up to 17 August 2021.
Results: Throughout the search of databases, 201 eligible experimental studies were recorded.
The results showed that the most commonly assessed inflammatory and oxidative stress biomarkers
were tumor necrosis factor (TNF)-α, interleukin (IL) 6, IL-1β, IL-10, malondialdehyde (MDA),
and nitric oxide (NO). The activity of antioxidant enzymes, including superoxide dismutase
(SOD), glutathione (GSH), and catalase (CAT) were assessed in the present review. Among herbal
treatments, Trigonella foenum-graecum L., Centella asiatica (L.) Urb., Vitis vinifera L., and
Moringa oleifera Lam. were most commonly used for diabetic complications. Due to the dispersion
of the treatments, meta-analysis was not applicable.
Conclusion: Our findings showed that the application of different plant-derived hypoglycemic
treatments in animal models improved diabetes and its complications, as well as modulated concomitant
inflammatory and oxidative stress biomarkers. These findings suggest that plant-based
antidiabetic medicines and food supplements have the potential to manage diabetes and its complications.
