Anti-diabetic properties and bioactive compounds of Teucrium polium L

ABSTRACT

Diabetes mellitus is a common metabolic disease with considerable morbidity and mortality. Untreated or improperly-treated diabetes can be associated with several long-term complications that necessitate an effective way to manage diabetes. Due to the side effects of synthetic glucose-lowering agents, alternative therapeutic modalities such as medicinal plants have attracted notable attention. Teucrium polium L. is a medicinal herb with antioxidant, antinociceptive, anti-inflammatory, hypolipidemic, hepatoprotective, and hypoglycemic properties. In vitro and in vivo studies have been conducted to characterize the anti-diabetic properties of Teucrium polium L. and its bioactive compounds. We conducted a literature study using Scopus, PubMed, and Google Scholar including the keywords "diabetes" and "Teucrium polium". We also scanned all the references cited by the retrieved articles. According to this review, Teucrium polium administration displayed anti-diabetic effects by targeting different mechanisms and pathways, such as enhancement of insulin secretion and insulin level, improvement of oxidative damage, regeneration of pancreatic β-cells, and promotion of glucose uptake in muscle tissues by increasing GLUT-4 translocation as well as inhibiting α-amylase activity. Although Teucrium polium has been widely regarded as a traditional method, the pharmacological studies on anti-diabetic effects are not sufficient, most studies are either in-vivo or in-vitro. The preclinical and clinical studies are further required to confirm the efficacy of Teucrium polium.
