Research on mangosteen (Garcinia mangostana) shows that it is a tropical evergreen tree, believed to have originated in the Sunda Islands and the Moluccas. The tree grows from 7 to 25 meters tall. The edible fruit is deep reddish purple when ripe. In Asia, the mangosteen fruit is known as the “Queen of Fruits,” while the durian (Durio spp.) is known as the “King of Fruits.” It is closely related to other edible tropical fruits such as button mangosteen and lemon drop mangosteen. The outer shell of the fruit is rather hard, typically 4-6 cm in diameter. Cutting through the shell, one finds a white; fleshy fruit 3-5 cm in diameter. Depending on the size and ripeness, there may or may not be pits in the segments of the fruit. The number of fruit pods is directly related to the number of petals on the bottom of the shell. On average a mangosteen has 5 fruits (round up figure). I have eaten a lot of exotic fruits in my life, including the King Of Fruits - durian, but I have never seen or tasted this Queen of Fruits. I bought the $30 bottle from my coworker and chucked down the mangosteen juice. I do feel more energetic for the rest of day, and I will have to let you know in the near future if it will help lose some weight!
