What does the evidence say about Hibiscus Tea Blood Pressure Randomized Trial?

Updated October 2026

Quick Answer

Hibiscus Tea Blood Pressure Randomized Trial has evidence relevant to benefits, uncertainty, and practical interpretation, but conclusions should stay close to the cited sources. One representative finding is: NO levels were significantly increased ( p = 0.012), whereas cortisol levels decreased significantly ( p = 0.008) after therapy with rosella tea in elderly women.

Key Takeaways

  • 01NO levels were significantly increased ( p = 0.012), whereas cortisol levels decreased significantly ( p = 0.008) after therapy with rosella tea in elderly women. [Yusni Y (2020)]
  • 02Conclusion Rosella has shown evidence to control and lower blood pressure, blood glucose, lipid profile, and cortisol in the elderly with metabolic syndrome. [Yusni Y (2020)]
  • 03They believe that rosella is effective in controlling metabolic syndrome, working with antihypertension, antidiabetic, antidyslipidemia and antiobesity effects. [Yusni Y (2020)]
  • 04The purpose of this study was to determine the effect of rosella in controlling metabolic syndrome through the secretion of blood nitric oxide (NO) and the cortisol pathway. [Yusni Y (2020)]
The current Migaku evidence database contains 2 reusable source documents for Hibiscus Tea Blood Pressure Randomized Trial. This answer focuses on benefits, uncertainty, and practical interpretation. - NO levels were significantly increased ( p = 0.012), whereas cortisol levels decreased significantly ( p = 0.008) after therapy with rosella tea in elderly women. [Yusni Y (2020); evidence level 4] - Conclusion Rosella has shown evidence to control and lower blood pressure, blood glucose, lipid profile, and cortisol in the elderly with metabolic syndrome. [Yusni Y (2020); evidence level 4] - They believe that rosella is effective in controlling metabolic syndrome, working with antihypertension, antidiabetic, antidyslipidemia and antiobesity effects. [Yusni Y (2020); evidence level 4] - The purpose of this study was to determine the effect of rosella in controlling metabolic syndrome through the secretion of blood nitric oxide (NO) and the cortisol pathway. [Yusni Y (2020); evidence level 4] - Using different drug regimens has been proved to have effective effects on lowering blood pressure, but the adverse effects of long-term usage such medications is evident. [Jalalyazdi M (2019); evidence level 4] Evidence levels are sorting aids, not final clinical grades. Level 1 usually indicates systematic-review style evidence, level 2 indicates randomized trials or public-health guidance, and lower levels need more cautious wording. This page is educational. People with medical conditions, pregnancy, medication use, or unusual symptoms should ask a qualified clinician before changing supplements, medication, or treatment routines.
