This study contributes to public health knowledge by evaluating rosella tea as a complementary therapy for hypertensive patients with comorbidities. The process involved a systematic review and meta-analysis of 10 clinical trials published from 2015 to 2025, identified through PubMed, ScienceDirect, Google Scholar, and ResearchGate. The implementation method followed PRISMA guidelines and used RevMan 5.4 to assess Mean Differences. The study schedule focused on analyzing the latest literature up to the year 2025. Results indicate that rosella tea consumption does not significantly lower blood pressure or lipid profiles. Consequently, patients should prioritize standard pharmacological treatments until further standardized research is available.
