Hibiscus flower

Traditional Uses & Why Herbalists Value It

Food traditions across Africa, Asia and the Americas steep roselle calyces into refreshing red drinks, served warm or chilled. Their tartness works well alone or with spices. The fleshy calyx is the usual tea material, even when called hibiscus flower.

What Modern Research Has Found

A six-week randomized trial in adults with mildly elevated blood pressure reported a greater reduction in systolic pressure with three daily servings of hibiscus tea than with placebo. Other trials and reviews also report favorable blood-pressure findings, with variation in preparation and study quality.

Plant Part, Preparation & Natural Constituents

Anthocyanins color the calyces. Species naming and calyx-versus-flower distinction matter for precise attribution.
