The Ayurvedic view of hibiscus
Gudhal (hibiscus) flowers and leaves are used in hair packs and a sour red tea. Some studies show hibiscus tea may modestly lower blood pressure.
Randomised trials, including one from Tufts University, found that two to three cups of hibiscus tea daily lowered systolic BP by a few points in people with mildly high BP. That is a real but small effect, similar to some lifestyle changes. It works best alongside less salt, more activity and prescribed medicines.
