A Randomized Prospective Placebo-Controlled Study of the Effects of Lavender Aromatherapy on Preoperative Anxiety in Breast Surgery Patients.
Brief description of study
Study participants will then be randomized into one of four groups; either they will receive 2 drops of lavender (Lavandula Angustifolia) oil (LO) or 2 drops of Michelia Alba Leaf oil (MA) or 2 drops of unscented Almond oil (AO) or two drops water on the inside of an oxygen face mask for 15 minutes. Linalool makes up ~30% of Lavandula Angustifolia oil and is believed to be its most active anti-anxiety component. Therefore we chose to compare LO with MA since the major constituent of MA oil is linalool making up 80% of its components. Before and after treatment, anxiety level will be measured using the Spielberger State-Trait Anxiety Inventory.
