Mangosteen (Garcinia mangostana) is a plant that grows in Southeast Asia.
The fruit is dark purple or red. The fruit pulp is slightly acidic and sweet.
Mangosteen contains chemicals that might act as antioxidants and fight infections.
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.
Don't confuse mangosteen with garcinia. These are not the same.
