Abstract

Hypertension is an increase in systolic or diastolic blood pressure that exceeds the threshold. In this research used gotu kola (Centella asiatica L.), which is contains several compounds that can act as anti-hypertension. The aim of this research is to determine the effect of gotu kola tea on blood pressure in hypertension patients. Analytical, quasi-experimental, time series design. The sample size calculation used the proportion of hypertension parameters from 22 people aged 60–70 years, simple random sampling technique. Data anayzed by T pair test analysis. There are a decrease of systolic and diastolic blood pressure in most respondents before and after consuming Centella asiatica tea. The T pair test results on blood pressure before and after consuming Centella asiatica tea showed a significant value of p = 0.000 in systolic and p = 0.002 in diastolic (α = 0.05) which means that in this study H1 results were accepted and H0 was rejected. The conclusion of this study is gotu kola tea can decrease blood pressure of hypertension patients.
