Key result
Young coconut water reduces systolic BP by ~35 mmHg, outperforming cucumber juice.
Why the study?
Pharmacological therapy for hypertension in the elderly is effective but may cause side effects, necessitating evaluation of non-pharmacological alternatives like cucumber juice and young coconut water.
Does young coconut water reduce systolic blood pressure more effectively than cucumber juice in elderly patients with hypertension?
Does young coconut water reduce systolic blood pressure more effectively than cucumber juice in elderly patients with hypertension?
Absolute Event Rate: 131.37% vs 145.69%
p-value: p=0.000
Both young coconut water and cucumber juice are effective non-pharmacological therapies for lowering blood pressure in elderly patients, with young coconut water showing a more pronounced reduction.
Young coconut water may reduce systolic BP more than cucumber juice in elderly hypertensives; leaves open confirmation in randomized trials.
Hypertension is a major non-communicable disease commonly affecting the elderly and poses a risk of severe complications. Pharmacological therapy is effective but long-term use may cause side effects, thus non-pharmacological alternatives such as cucumber juice and young coconut water are required. This study aimed to evaluate the effectiveness of cucumber juice and young coconut water on blood pressure changes among elderly patients with hypertension at Bukit Selabu Public Health Center in 2025. A pre-experimental design with two group pretest–posttest was applied. A total of 30 elderly respondents were selected through purposive sampling, consisting of cucumber juice group (15) and young coconut water group (15). Interventions were given for 7 consecutive days: 200 ml/day of cucumber juice and 250 ml/day of young coconut water. Blood pressure was measured using a digital sphygmomanometer and analyzed using Paired Sample T-test and Independent T-test. Results showed a significant reduction in systolic blood pressure: from 150.03 to 145.69 mmHg (p=0.000) in the cucumber juice group, and from 166.84 to 131.37 mmHg (p=0.000) in the young coconut water group. In conclusion, both cucumber juice and young coconut water effectively reduced blood pressure in elderly patients, with greater reduction observed in the young coconut water group.

Nani et al. (2026) studied Hypertension (n=30). Young coconut water vs. Cucumber juice 200 ml/day was evaluated on Systolic blood pressure at 7 days (p=0.000). Young coconut water significantly reduced systolic blood pressure from 166.84 to 131.37 mmHg (p=0.000), demonstrating a greater reduction than cucumber juice.
