Is Hibiscus Tea Blood Pressure Randomized Trial safe?

Updated October 2026

Quick Answer

Hibiscus Tea Blood Pressure Randomized Trial has evidence relevant to safety, limits, and clinician-discussion contexts, 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 safety, limits, and clinician-discussion contexts. - 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.
