An Evaluation of Anti-Hypertensive Property of Hibiscus sabdariffa

Abstract

Hypertension is the primary worldwide cause of cardiovascular disease and early death. Because of the extensive use of anti-hypertensive treatments during the past 40 years, the mean blood pressure (BP) over the world has either decreased dramatically or remained constant. Contrastingly, hypertension has increased in prevalence, especially in low- and middle-income countries. There is evidence of decreasing the incidence rate of hypertension however, it has been noted that there are more and more side effects that are being discovered associated with high-cost chemical treatments. Therefore, Phyto-based traditional medicine is now being investigated for its safety and lowcost characteristics. One of the main phyto-based treatments for hypertension is Hibiscus sabdariffa, which has been used by different countries. However, a comprehensive approach for evaluating the efficacy of this plant, its extracts, and beverages is still lacking. Therefore, this study aims to provide a review and compilation of the clinical trials and animal studies documenting and evaluating the effectiveness of H. sabdariffa for the effective management of hypertension in individuals with low to severe hypertension issues. Thus, this study can pave the pathway for future research to focus on the limitations that are confronting harnessing the full potential of Hibiscus sabdariffa.
