Context/Background: Hypertension is a leading cause of death in Indonesia, with a prevalence of 34.11% in adults over 18. The combination of Belimbing Wuluh and basil leaves shows potential as an alternative therapy for reducing blood pressure, particularly for the Prolanis group. Aim/Objective: The research aims to evaluate the combined effect of belimbing wuluh and basil leaves on blood pressure among Prolanis groups in Parepare City's Lumpue and Lakessi primary health centers. It includes assessing respondent characteristics and comparing blood pressure changes before and after treatment with belimbing wuluh, basil, and a control group. Methodology: The method used is a Quasi-Experimental design with a randomized control group pretest-posttest, involving 48 respondents divided into three groups: combination intervention, belimbing wuluh leaves intervention, and basil leaves intervention. The study was conducted at Puskesmas Lumpue and Puskesmas Lakessi in Parepare City. Data analysis utilized Friedman test, one-way ANOVA, Tukey test, and Kruskal- Wallis test. Results : Conclusions : There is a significant difference in the change in blood pressure among the three different intervention groups: the combination of basil leaves and Belimbing Wuluh leaves, the basil leaves intervention group, and the Belimbing Wuluh leaves intervention group (p=0.0133). Studies show that the combination of basil leaves and belimbing wuluh leaves is more effective in reducing blood pressure in hypertensive patients compared to using basil leaves or belimbing wuluh leaves separately at Lumpue Health Center and Lakessi Health Center in Parepare City.
