PENGARUH PEMBERIAN SEDUHAN KELOPAK KERING BUNGA ROSELLA (Hibiscus sabdariffa) TERHADAP TEKANAN DARAH PENDERITA PREHIPERTENSI DAN HIPERTENSI GRADE 1 YANG DIEDUKASI GAYA HIDUP SEHAT

Abstract

Background: Hypertension is a chronic disease leads to various complications. Treatment with standard drugs may cause undesirable side effects. Previous studies demonstrated Hibiscus sabdariffa’s (HS) potency for antyhipertensive phytopharmacy. HS has bioactive compound to lower blood pressure and easy to be cultivated. This study objective is to analyze the effect of HS infusion coupled with lifestyle education to blood pressure in prehypertension and hypertension grade 1 patients. Methods: The study design was Non-randomized Control Group Pretest-Postest Design with Consecutive Sampling Approach. Subjects were 40 people divided into 2 groups (treatment, n:19, control, n:21). Treated group were given lifestyle education and HS dried calyx infusion with a dose of 3gr/200ml consumed daily before breakfast. The control group was given only lifestyle education. After 4 weeks, blood pressure was measured. Data were analyzed with paired t-test and independent t-test. Results: The comparison between pre and post test systolic pressure in the treated group (p=0.000), the control group (p=0.039), and diastolic pressure in the control group (p=0.038) showed significant result. There is no association on diastolic pressure in treated group (p=0.116). Comparison of systolic pressure reduction between the control and treatment group showed significant differences (p=0.003), but there is no association in diastolic pressure reduction (p=0.872). Conclusion: Dried calyx infusion of Hibiscus sabdariffa shows systolic blood pressure reduction significantly. Healthy lifestyle also influences the decrement of blood pressure which was also shown in the control group.
