RESUMEN
Introduction@#This study aimed to determine the effectiveness of basil tea as an adjunct to antihypertensive medications in decreasing the blood pressure of hypertensive subjects.@*Methods@#Hypertensive patients were randomly allocated into either experimental (antihypertensive medications + basil tea) or control (antihypertensive medications alone) group. Experimental subjects drank basil tea twice daily for 28 days, with blood pressure readings done at baseline and on a weekly basis for four weeks.@*Results @#A significant difference in systolic blood pressure was elicited for both treatment (p=0.005) and control (p=0.034) groups. There is a significant difference in the mean systolic (p=0.021) and diastolic blood pressure P (p=0.023) between the two groups at the fourth week in the basil tea group. There was a significant difference (p=0.046) in the mean difference in diastolic blood pressure from baseline to Week 4 in the basil tea group. There was a statistically significant decrease in systolic blood pressure between baseline and Week 4 (p=0.05).@*Conclusion@#Basil tea, used as an adjunct to anti-hypertensive medications, elicited a statistically significant reduction in systolic blood pressure and a statistically significant difference in change of diastolic blood pressure after four weeks of treatment.
