Kola nut commonly called bissy in Jamaica, came to the island on a slave ship in 1680. Bissy was formerly an ingredient in cola bottle drinks. It is widely regarded for its medicinal properties because of its effect as an antidote for poisons. It relieves menstrual cramps, headache, gout, rheumatism, jaundice, nausea, vomiting, and indigestion. Bissy is further used in birth control preparations, aids in the control of diabetes, and overweight. The drink comes from the seed that is grated and brewed. It can be sweetened with sugar or honey. Some people say they drink it when they are ill but some say they just drink it as a tea for the great flavour.
