This study aims to determine the effect of aromatherapy (lavender oil) application on the anxiety level of relatives of patients admitted to the emergency department.

The hypotheses of the study are as follows:

H1: Aromatherapy (lavender oil) application has an effect on the anxiety level of relatives of patients presenting to the emergency department.

H0: Aromatherapy (lavender oil) application has no effect on the anxiety level of relatives of patients presenting to the emergency department.

In the experimental group; After the patient is registered in the emergency department, the participant introduction form and state-trait anxiety scales will be applied as a pre-test to the relatives of the patients who agree to participate in the study. The participants will be made to smell lavender oil dropped on gauze by the researchers for an average of 3-5 minutes. After the intervention, the state and trait anxiety scales will be applied as a post-test approximately 15 minutes later.

In the control group; After the patient is registered in the emergency department, the participant introduction form and state-trait anxiety scales will be applied as a pre-test to the relatives of the patients who agree to participate in the study. No intervention will be made to the participants in the control group. After a certain waiting period (after an average of 15 minutes), the state and trait anxiety scales will be applied as a post-test.
