Background: Hypertension is a major health problem worldwide. Increased vascular resistance, sodium retention & sympathetic over activity contributes to the blood pressure elevation. Plant foods may be beneficial in decreasing blood pressure (BP). Recently much attention has been focused on plant foods that may be beneficial in preventing Hypertension, metabolic syndrome and possibly reduce the risk of various diseases. This  clinical  study  was  conducted  to  test  the  effectiveness  of  a  structured  intervention on BP   of  primary  hypertensive subjects. Aim: To study the effect of Tender Coconut Water (TCW) on BP of Primary hypertensive subjects. Methods and Material: 70 subjects were selected randomly sample for 6 weeks of the intervention program. Among them 40 subjects were selected as the experimental group and 30 300ml/day for 6 weeks whereas the control group was instructed to follow the same routine without modifications. One initial, two mid intervention (after every 15 days) and one final (post intervention) BP recorded for both the groups. The obtained data was statistically analyzed. Results: The mean systolic BP of experimental group and control group were decreased from 145.8 mm Hg and 141mm of Hg to 135.3 mm of Hg and 140 mm of Hg respectively.  The mean diastolic BP of  experimental group and control group were decreased from 93.7 mm H g and 90.9 mmHg to 86.9 mm of Hg and 89.7 mm of Hg respectively. Conclusion:  Irrespective of cause of hypertension TCW has beneficial effect on BP. TCW contains high amount of potassium which causes vasodilatation and also improve the endothelial function.
