Abstract:
rtension is systolic blood pressure increases above 140 mmHg and diastolic blood pressure increases
above 90 mmHg. One of the hypertension treatments is non-pharmacological therapy by giving lemon
aromatherapy, which is helpful as an antioxidant, strengthens and vasodilation of blood vessels, and
controls blood pressure. This study aimed to analyze the effectiveness of lemon aromatherapy on blood
pressure in hypertension patients at Modopuro Public Health Center Mojokerto. The research design used
pre-experimental with a one-group pre-post test design approach. The sample used 35 respondents with a
purposive sampling technique. The research instrument used a digital tensimeter and a blood pressure
observation sheet. Statistical analysis test used the Paired t-test. The results showed that the mean systolic
blood pressure before intervention was 158.34 mmHg, and the mean systolic blood pressure after
intervention was 144.42 mmHg. The results showed a significant difference between systolic blood
pressure before and after giving lemon aromatherapy in hypertension patients (p-value = 0.000; α <0.05).
Lemon aromatherapy can decrease blood pressure in hypertension patients, affecting the olfactory and
circulatory nervous systems. When aromatherapy is inhaled, the olfactory nerve delivers impulses to the
brain and stimulates the production of endorphins, which can calm and relax the body. That mechanism
can cause vasodilation of blood vessels and a decrease in heart rate so that blood pressure will decrease.
