Still not convinced? Let's look at another Nigerian based study with Hibiscus vs Hydrochlorothiazide (HCTZ), which is usually prescribed to African Americans as a starting therapy.
Once again these patients had mild to moderate hypertension and once again both HCTZ and Hibiscus tea showed a significant decrease in blood pressure and once again, Hibiscus beat out the medication!
Let's look at the numbers, and I need you to follow me on this one because I am about to drop a BOMB.
At the end of the 4-week treatment, systolic BP (SBP) decreased by 12.9 mmHg with HCTZ and 17.08 mmHg with Hibiscus. There were similar results with the diastolic numbers as well. HCTZ decreased diastolic by 9.50 mmHg, and Hibiscus decreased diastolic by 11.12 mmHg.
However, 1-week after withdrawal of treatment, the fall in SBP, DBP in the Hibiscus group were still significant compared to those of placebo, while blood pressure returned to baseline levels in HCTZ group!!
How could the blood pressure return right back to where it started after stopping the medications? That's because medications do not address the issue, which is endothelial dysfunction!
Again there were no side effects for the Hibiscus group unlike the side effects experienced for the HCTZ, such as potassium depletion, cramps, and frequent urination. But once again, don't take my word for it, have a look for yourself => Nigerian Study 2
