Overview Information

Ackee is a plant that produces fruit. It is found in West Africa, the Caribbean, southern Florida, and Central America. Ripe ackee fruit is eaten as food and is considered a dietary staple in Jamaica. However, unripe ackee fruit is very poisonous. Most ackee products have been banned from import into the US for the past 30 years because of concerns about poisoning from unripe fruit. The US has just recently begun to allow the import of canned ripe ackee on a limited basis.

People try taking ackee for a long list of conditions. But there is no good scientific evidence to support these uses, and eating unripe ackee fruit can be dangerous.
