Noni (Morina citrifolia) is a hardy tree that was introduced to Hawaiʻi by early Polynesian settlers. This tree can survive through a variety of environmental conditions including wind, drought, overwatering, high winds and even fire. Its uniquely shaped fruits turn yellow-white when ripe.

Although noni fruits are famous for their pungent smell, they are edible and are an important part of Hawaiian culture. They can be used to treat skin conditions like boils, bruises and wounds and have even been used to treat broken bones when mashed together with salt. Fruit oil is used to make hair extract, and the parts of the plant are also used in tonics to treat certain illnesses and to make yellow and red (when lime is added) dyes.
