A friend of mine has recommended it. Xanga is a drink made from the skin and fruit of the mangostene fruit. Apparently, it has been recognized for centuries in non-western medicine as curative for all kinds of ailments and there are incredible stories of it shrinking tumors, aiding asthma, etc. My friend says it is an anti-inflammatory, so she thought I might want to consider it for my daughter. Apparently, it has been studied by universities, etc. and doesn't pose a risk of toxicity. Has anyone heard of it? Used it?
