Noni fruit in 3 different stages. Never seen this before! Noni (Morinda citrifolia) is a member of the Coffee family (Rubiaceae family...other members of this family include Cinchona bark and the Bedstraws (I.e. Cleavers and Sweet Woodruff)). If you examine the flowers of Coffee, Cinchona, Noni and the Bedstraws, you can see an interesting resemblance in their shape, and color (all have 4-5 petaled, curved white flowers (Cinchona often with pink hues)). The flowers of Noni attract species of weaver ants, and together they form a symbiotic relationship. The ants feast on the nectar and pollinate, and in turn they also protect against other parasitic insects.
Noni is native to Southeast Asia and Australasia, but is now cultivated or naturalized in many other tropical areas. One of its common names is 'Cheesefruit', because of its distinct flavor/smell. Though the flavor of Noni is absolutely vile when ripe (in my opinion), it is rich in phytochemicals and nutrients. This grants it numerous health properties including immuno-stimulant, anti-cancer/anti-tumor, anti-microbial, and anti-inflammatory (skin, digestive system, joints). It also contains 17 amino acids and has a powerful array of antioxidants (selenium, coenzyme Q10, flavonoids, etc.).
