Abstract:
Background:
A significant risk factor for cardiovascular disease, hypertension, affects more than a billion people globally. Numerous non-pharmacological
methods work well to lower blood pressure. The objective of this study was to assess the short-term effect of green tea supplementation on blood
pressure among people with hypertension.
Methods:
This community-based randomized controlled trial was conducted among people with hypertension recruited using a purposive sampling technique
from the village of Lakhnaur, Mohali, Punjab, India. Sixty patients were randomly assigned to receive either supplementation with green tea
beverage (one cup/day) or no intervention. The primary outcome measure was systolic and diastolic blood pressure. Blood pressure was measured
at the baseline and 15 days after the intervention using a standard calibrated digital sphygmomanometer.
Results:
Post-intervention, the decrease in the mean systolic blood pressure was significantly greater (p <0.01) in the experimental group (129.83±6.497)
than in the control group (135.0±6.433).
Conclusion:
Green tea supplementation significantly lowered the systolic blood pressure among study participants. Green tea may be included as part of a
lifestyle intervention to manage and control systolic blood pressure in hypertensive patients.
