Roselle juice, known as bissap, wonjo, foléré, dabileni, tsobo, zobo, siiloo, or soborodo in parts of Africa, karkade in Egypt, sorrel in the Caribbean, and agua de Jamaica in Mexico, is a drink made out of the flowers of the roselle plant, a species of Hibiscus.

Bissap is a versatile crop that has many uses. Senegalese women add bissap leaves to popular dishes such as ceebu jën and also brew the flowers into a sugary juice or tea. Hibiscus contains antioxidants and has been found to reduce blood pressure.
