Hibiscus at a Glance
Hibiscus sabdariffa is a tropical member of the Malvaceae family. The deep red fleshy calyces surrounding the seed capsule are the familiar part used for tart teas and foods.
Food and Traditional Use
Hibiscus drinks are popular across Africa, the Caribbean, Latin America and the Middle East under many regional names. The calyces provide a tart flavor and rich red color.
Research
Clinical trials suggest regular hibiscus tea may modestly lower blood pressure in some adults. Effects vary and hibiscus should not replace prescribed antihypertensive treatment.
Preparation
Dried calyces are commonly infused hot or cold and may be sweetened or blended with spices and fruit.
Safety
Hibiscus tea is generally well tolerated as a food beverage. Because it may lower blood pressure or blood glucose modestly, concentrated use deserves caution with antihypertensive or diabetes medicines. Pregnancy data for medicinal use are limited. Allergy is possible, including in people sensitive to other Malvaceae plants.
Folklore and Culture
Hibiscus is associated with hospitality, celebration, beauty and love in many modern folk traditions, though meanings vary by culture.
Bottom Line
Hibiscus is first a globally important food and beverage plant, with useful but modest blood-pressure research. For educational purposes only.
