Hibiscus Tea Only Works If You Use It Like This
In this video, Dr. Columbus Batiste breaks down why hibiscus tea may lower blood pressure in clinical trials but still seem to “do nothing” for many people in real life, showing how the research depends on the right plant part, a strong infusion, enough daily servings, and enough time to see an effect; he explains the main pressure-lowering mechanisms hibiscus may influence, including ACE-like activity, mild diuretic effects, endothelial and nitric oxide support, and calcium-channel-like vascular relaxation — and then gives a simple evidence-based hibiscus protocol so viewers can stop drinking weak red water and start using the tea in a way that actually matches the studies.
