Jamaica - Hibiscus sabdariffa
Although referred to as "jamaica flowers" these are actually hibiscus calyxes (the cover over the blossoms before they open). The flowers are used in Mexico for a tangy deep red "cooler" called Aqua de Jamaica.  Other names for the "jamaica flowers" include "hibiscus flowers", "roselle" and "Jamaica sorrel".  In Mexican grocery stores the common terms are either "jamaica" or " flores de jamaica".

The plant is native from India to Malaysia and is now widely grown throughout the tropics and subtropics.

Buy and Store
Jamaica flowers can be purchased in most Mexican grocery stores and markets as well as health food stores. Select deep crimson color flowers and avoid the older faded flowers.  

Store the flowers in a container with a tight fitting lid or a zip lock bag.  Store in a cool, dry location for up to one year.  

Medicinal Uses
Jamaica flowers, as well as the leaves of the same plant are used medicinally In India, Africa and Mexico.  Various infusions are used as a diuretic, cholerectic, febrifugal and hypotensive.

There have been animal studies that show that an extract made form the jamaica flowers decreased the absorption rate of alcohol and a similar concoction is used in Guatemala as a hangover remedy.

Additionally it is used as a lotion for sores and wounds.
