Hibiscus is a bushy annual plant. Parts of the flower are used to make a popular drink in Egypt called Karkade. Various parts of the plant are also used to make jams, spices, soups, and sauces. The flowers are used to make medicine.
The hibiscus has had a lengthy history of use in Africa and neighboring tropical countries. Its fragrant flowers have been used in sachets and perfumes. In areas of northern Nigeria, this plant has been used to treat constipation. Fiber from H. sabdariffa has been used to fashion rope as a jute substitute. The fleshy red calyx is used in the preparation of jams, jellies, and cold and warm teas and drinks. The leaves have been used like spinach. The plant is used widely in Egypt for the treatment of cardiac and nerve diseases and has been described as a diuretic. In Iran, drinking sour tea for the treatment of hypertension is a popular practice. It has been used in the treatment of cancers. Research reveals little or no evidence of these medicinal uses of hibiscus. The mucilaginous leaves are used as a topical emollient in Africa. In Western countries, hibiscus flowers often are found as components of herbal tea mixtures. In Thailand, people consume roselle juice to quench thirst. Karkade seed products (ie, karkade defatted flour, protein concentrate, protein isolate) have been studied for their nutritional and functional value.
