A Systematic Review of the Therapeutic Properties of Lemon Essential Oil

Lemon essential oil derived from the Citrus limon plant has been used in various traditional medicinal practices for centuries. Its bright, citrusy aroma and versatile applications have made it a popular choice in aromatherapy, skincare, and alternative medicine. This systematic review examines the therapeutic effects of lemon essential oil. From an initial 1330 articles, eight studies met the inclusion criteria. The results consistently demonstrated lemon essential oil efficacy in reducing anxiety. Significant reductions in anxiety were observed in students during exams, Acute myocardial infarction patients, and pre-surgical patients. Physiological benefits included reduced blood pressure and heart rate in Acute myocardial infarction patients. Enhanced cognitive performance and reduced test anxiety were noted among students. In oral health, lemon essential oil significantly improved measures related to halitosis. Future research should explore lemon essential oil's long-term effects, optimal dosing, and mechanisms of action. Given its safety and therapeutic potential, lemon essential oil warrants further investigation, particularly for applications in palliative care, where it may enhance the quality of life by alleviating anxiety and pain.
