Benefits of Mangosteen
The Fruit
The mangosteen fruit is consumed fresh and can be processed into jams, preserves, and candies. It is an important seasonal fruit consumed throughout South and East Asia and regarded by many as one of the best flavored in the world. In China, the fruit rind is used for tanning leather because it contains 7 to 14% catechin tannin and rosin. It also yields a black dye.
