Hypertension is the leading risk factor for mortality. There is growing evidence that non pharmacological interventions like Diet Therapy, Music, Yoga, Breathing and other relaxation techniques lower high blood pressure. Objectives of the Study: 1. Identify the prevalence of hypertension in the selected urban area. 2. Assessment of contributing factors for hypertension.3. Assessment of blood pressure among hypertensive clients. 4. Determine the effect of lemon juice in reduction of blood pressure among hypertensive clients. Methods: The research design adopted was pre-test post-test design with comparison group-a type of quasi experimental design. The sample size was 30 which included 15 for experimental and 15 for comparison group. Results: In the experimental group, the mean systolic blood pressure was 145.8 mmHg on the 1st day, 135.8 mmHg on the 30th day and reduction of blood pressure was 10 mm Hg. In the comparison group, the mean systolic blood pressure was 145.6 mmHg on the 1st day, 146 mmHg on the 30th day and mean difference was 0.66mmHg.The paired ‘t’ test value of systolic and diastolic blood pressure in the experimental group (t=17.8, 8.4) was greater than the table value at p=0.001 level. This showed that there was a significant reduction in blood pressure among the experimental group. The paired‘t’ test value of systolic and diastolic blood pressure in the comparison group (t=2.7, 3.7) was less than the table value at p=0.001 level. This showed that there was no significant difference in blood pressure among the comparison group. The independent‘t’ test value of systolic, diastolic (t=4.5, 4.6) was greater than the table value of p=0.001 level. This showed that there was a significant result
