Native to southeastern Asia, mangosteen (Garcinia Mangostana) is a purple-skinned, white fleshed fruit that has been called the one of world's most delicious. In the United States, mangosteen juice may outshine the fruit because of its widely marketed health benefit claims. Research to lay a scientific foundation for those claims is ongoing.
According to the American Cancer Society, promoters of mangosteen juice and other products claim they improve immune system function, joint flexibility and mental performance. They also say mangosteen is a remedy for infection, TB, and diarrhea.
Nineteenth-century researchers isolated an antioxidant, mangostin, from mangosteen rind. Studies on rats done in the 1970s found that this compound, xanthone, relieved inflammation.
In a 2003 study at Bangkok's Srinakharinwirot University, mangosteen's xanthones Garcinone B and E showed in vitro effectiveness against TB bacteria. 2002 research at Taipei's Veteran's General Hospital found that Garcinone E has cytotoxic properties against liver cancer cells.
At least one mangosteen juice manufacturer claims to use the xanthone-rich rinds in its juice formula but posts a disclaimer saying that potential mangosteen juice benefits aren't FDA-evaluated.
While ongoing research is building support for mangosteen's health benefits, there is no current proof that mangosteen juice can treat or cure any specific condition.
