Non-hemorrhagic stroke occurs due to an interruption of blood flow to the brain caused by thrombus or embolus blockage in blood vessels. Stroke patients may experience psychological problems, including emotional instability, depression, and anxiety. One non-pharmacological intervention to reduce anxiety is lavender aromatherapy, which provides a relaxation effect. This study aimed to determine the effect of lavender aromatherapy on anxiety levels in non-hemorrhagic stroke patients. The study used a quantitative approach with a quasi-experimental one-group pretest-posttest design. The sample consisted of 36 non-hemorrhagic stroke patients in the working area of Mranggen 2 Community Health Center, selected using purposive sampling. Data were collected using the Hamilton Anxiety Rating Scale (HARS) questionnaire and analyzed through univariate and bivariate analysis using the Wilcoxon test. The results showed that before receiving lavender aromatherapy, most respondents experienced moderate anxiety (22 respondents; 61.1%). After the intervention, most respondents experienced mild anxiety (21 respondents; 58.3%). The Wilcoxon test showed a significance value of 0.000 (p < 0.05), indicating that lavender aromatherapy significantly reduced anxiety levels in non-hemorrhagic stroke patients. Lavender aromatherapy can be used as an effective complementary therapy to manage anxiety among stroke patients.
