Aromatherapy in the Control of Stress and Anxiety

Background: Currently, complementary and alternative medicine emerge as important therapies in the prevention and treatment of various health problems. In view of this, the present study aims to evaluate the efficacy of essential oils in reducing stress and anxiety levels in aromatherapy users, at a clinic of Braganca, Portugal. Methods: A study was performed with 36 individuals divided in two distinct groups: “aroma group” and “control group”. Individuals of "aroma group" were treated with a mixture of essential oils of Lavandula angustifolia Mill and Matricaria recutita L. applied with Effleurage massage while the individuals of "control group" received only Effleurage massage. Stress and anxiety levels of all individuals participating in the study were evaluated before and after the treatment. Additionally, the chemical composition of the essential oils was evaluated by GC and GC-MS. Results: In the aromatherapy assay, the “aroma group” showed a significant decrease of 12% and 30%, in stress and anxiety levels, respectively, in the “control group” this decrease was lower (3.3% and 2.6% for stress and anxiety levels, respectively).
