This study aims to determine the effects of lavender oil inhalation on anxiety, sleep quality, and blood pressure in patients with primary hypertension. The study is designed as a double-blind randomized controlled trial. The study population consists of patients presenting to the Cardiology Outpatient Clinic of Ardahan State Hospital. Participants are randomly assigned to an experimental group, which will receive a total of 12 lavender oil inhalations three times a week for one month, or to a control group, which will continue routine treatment and care. Data will be collected using the Hypertension Diagnostic Form, Beck Anxiety Inventory, and Pittsburgh Sleep Quality Index. Statistical analyses will be conducted to compare outcomes between the experimental and control groups.

The study uses a parallel assignment design with two groups: an experimental group receiving lavender oil inhalation and a control group receiving routine care. Participants are randomly assigned to one of the two groups. The study is double-blinded: neither the participants, the researchers administering the intervention, nor the statisticians analyzing the data know group assignments. Outcomes (anxiety, sleep quality, and blood pressure) are measured before and after the one-month intervention period.

Participants, the interventionist, and the statistician are blinded. Patients are randomly assigned using simple randomization (odd-numbered to one group, even-numbered to the other). Group allocation (lavender oil or control) is determined by an independent nurse. Separate consent forms and coded data entry (groups as 1 and 2) ensure blinding is maintained.
