The roots, leaves, bark and skin of the fruit (shell or pericarp) are used both internally and externally to treat a wide variety of diseases. Various supplements, such as capsules, pills, and mangosteen fruit juice, are available at several health food stores. Studies have suggested that the fruit has antioxidant and anti-inflammatory properties. However, there is not yet enough evidence to prove this conclusively.
There are many mangostean-based products, including supplements and juices, available to people who want to get the health benefits of mangosteen but struggle to find fresh fruit.
