Mangosteen (Garcinia mangostana) is a tropical evergreen tree with edible fruit native to tropical lands surrounding the Indian Ocean. Its origin is uncertain due to widespread prehistoric cultivation, and it grows mainly in Southeast Asia, southwest India, and other tropical areas such as Colombia and Puerto Rico, where the tree has been introduced. The fruit is dark purple or red, and the fruit pulp is slightly acidic and sweet. The fruit is sometimes referred to as purple mangosteen because of the deep purple color its rind develops when ripe. Mangosteen is highly valued for its juicy, delicate texture and slightly sweet and sour flavor. Here are some key facts about mangosteen:

• Nutrients: Mangosteen is relatively low in calories yet provides many essential nutrients, including vitamin C, folate, and dietary fiber.

• Antioxidants: Mangosteen contains several nutrients with antioxidant capacity, such as xanthones, which are a unique type of plant compound known to have strong antioxidant properties. In several studies, the antioxidant activity of xanthones has resulted in anti-inflammatory, anticancer, anti-aging, and antidiabetic effects.

• Uses: People use mangosteen for serious gum infections, obesity, muscle strength, diarrhea, and many other conditions, but there is no good scientific evidence to support most of these uses. Mangosteen has been consumed as fruit, juice, and used as traditional medicine. Mangosteen has been used to treat skin infections and diarrhea.

Mangosteen is easy to prepare and eat, though it may be difficult to find depending on where you live. The fruit’s season is relatively short, which often limits its availability. Your best bet is to look for it at specialty Asian markets, but be aware that fresh mangosteen can be quite expensive. Frozen or canned forms may be cheaper and easier to find, but be mindful that canned versions often contain added sugar.
