Abstract
The goal of the study is to potentially support the existing evidences regarding the efficacy of the Rosmarinus officinalis, as the potential therapeutic and anti-oxidative agent, serving a viable role in the control of metabolic syndromes such as diabetes mellitus.This study has adopted qualitative research design to gather secondary data and/or information and explore the antioxidant and anti-hyperglycaemic effects of Rosmarinus officinalis L. on the oxidative stress of diabetic rats. The secondary sources that were accessed to gather relatively valid and reliable information include published journal articles, research papers and eBooks.As a result of analysis, it has been observed within the rats placed in the diabetic group the levels of markers, including superoxide dismutase (SOD), reduced glutathione (GSH), as well as catalase (CAT) were significantly lower. The rosemary extracts have the greater potential to significant affect the oxidative stress among diabetic rats thus, it could be considered as the most efficient and effective antioxidant.
