Traditional Uses:

Polynesians picked the noni fruit before it was ripe, and place it in a jar in the
direct sunlight. When fully ripe, the noni fruit was mashed into a puree and the juice
was extracted through a cloth. The juice was then ready for use. People traditionally
took the juice during times of rest, when the body was under the least amount of stress. Noni was also served as a food dish.
