Hibiscus tea, also called sour tea because of its tart taste, is made from a mixture of dried hibiscus flowers, leaves, and dark red calyces (the cup-shaped centers of the flowers). After the flower finishes blooming, the petals fall off and the calyces turn into pods. These hold the plant’s seeds. Calyces are often the main ingredients in herbal drinks containing hibiscus.Hibiscus has been used by different cultures as a remedy for several conditions.
