Mangosteen Juice (Garcinia Mangostana) is believed to have originated in Asia, however today is grown in a number of

tropical regions throughout the world including Thailand, India, Malaysia, and Brazil.  It has been commonly referred to in Asia as "the queen of fruits" because of its great taste.   It many areas, mangosteen juice is so popular that demand can outpace the supply.  Despite being utilized in Asia for hundreds of years for its medicinal benefits, until recently mangosteen had never been introduced to North America and Europe.  Mangosteen juice has grown rapidly in popularity since its introduction to the US market.
Because of the numerous benefits reported by people taking mangosteen for pharmaceutical purposes, Mangosteen has been the subject of many scientific studies.  It is believed that the benefits of mangosteen come from the Xanthones that are found naturally in the mangosteen fruit.  Xanthones are natural chemical substances that have an incredibly high antioxidant content.  Mangosteen contains over 20 different xanthones.  In addition to the xanthones, mangosteen also contains other biologically active substances such as catechins, polyphenols and polysaccharides which are believed to be responsible for the antibacterial and anti-fungal effects of the fruit.
Mangosteen is believed to have positive benefits on many different body systems.  Here are a few examples.
Skeletal System - Natives of Asia first used mangosteen to stop inflammation of the intestines.  Scientist in India and Japan began investigating mangosteen believing that it might help inflammation in other parts of the body.  Their studies have demonstrated that mangosteen has powerful anti-inflammatory properties.
Cardiovascular System - The xanthones in mangosteen are very potent antioxidants and research has shown that these xanthones can have a positive effect on preventing atheroclerosis or hardening of the arteries.
Immune System - Xanthones have been shown to have anti-viral, anti-fungal and anti-bacterial properties.  In a recent independent study, Thai-Go was shown to be effective at stimulating the immune system with twice the potency of the biggest competing product.
