Hibiscus Tea (Hibiscus sabdariffa) – A Scientific Overview

General Characteristics and Morphology

Hibiscus tea, derived from Hibiscus sabdariffa, is a perennial herbaceous plant belonging to the Malvaceae family. It thrives primarily in tropical and subtropical regions, growing to a height of 1 to 2 meters. The plant features reddish stems, palmate leaves, and large flowers that are deep red to purplish in color. After blooming, the flowers develop into fleshy calyces, which constitute the primary medicinal part of the plant.
