Overview

Ackee (Blighia sapida) is an evergreen tree that makes fruit. Ripe ackee fruit is commonly eaten as food in Jamaica. Unripe ackee fruit is poisonous.

The ripe ackee fruit contains fatty acids. The unripe ackee fruit contains poisonous chemicals that can cause dangerously low blood sugar, liver damage, and death. Most ackee products have been banned from import into the US due to concerns about poisoning from the unripe fruit.

People use ackee for many conditions, but there is no good scientific evidence to support any use. Eating unripe ackee fruit is unsafe.
