Essential Oil Applications in Diabetes Management
Summary
Essential oils are complex mixtures of plant‐derived volatile compounds that have attracted significant interest as complementary agents in the prevention and management of diabetes mellitus. Their multifaceted bioactivity encompasses modulation of carbohydrate‐digesting enzymes, enhancement of insulin sensitivity, and mitigation of oxidative stress. By inhibiting α‐amylase and α‐glucosidase, certain oils slow post‐prandial glucose excursions. Other constituents stimulate peripheral glucose uptake and suppress hepatic gluconeogenesis. Concurrent antioxidant properties counteract hyperglycaemia‐driven free‐radical generation, protecting pancreatic β‐cells and vascular endothelium. Encapsulation technologies have improved oil stability and bioavailability, facilitating incorporation into functional foods, nutraceutical formulations and topical preparations. Preclinical and early clinical evidence supports the use of oils such as cinnamon, fenugreek and bergamot as adjuvant therapies for glycaemic control and reduction of diabetes‐related complications. Ongoing research seeks to define optimal dosing, delivery systems and synergistic combinations with established pharmacotherapies to enhance efficacy while maintaining safety.
