Mangosteen has been used for centuries in folk medicine as well as the traditional medicine systems throughout Southeast Asia. Recently, more mangosteen research studies has uncovered additional properties such as Anti-inflammation, Anti-tumor, Anti-aging, Anti-oxidant, Anti-viral, Anti-bacterial, and Anti-diabetic. Although this research is still being studied, it appears that mangosteen derives its health benefits because of anti-oxidants known as Xanthones that are found throughout the entire plant. However, the greatest amount, over 80% in fact, being found in the "pericarp" or inner rind of the fruit.The mangosteen trees that are used for Faro's mangosteen products are organically grown in pristeen forests without pesticides, herbicides or fertilizers. Each mangosteen fruit is selectively picked and only the fruits that are dark red to purple in color are chosen...indicating a perfect state of ripeness for the highest nutritional value.The pericarp is then removed from the white fruit inside. The fruit is removed and used for other purposes. But the outer skin (or pericarp) is laid out and exposed to the sun...a natural drying process that has been used in Southeast Asia for centuries and has not been improved upon even with today's modern equipment and science. Sun-dried pericarp yields the highest tannin concentration of 5.5% and is preferred for medicinal usage over any other drying methods.After the drying process is complete, the sun dried pericarp pieces are then ground to a fine powder. Faro's mangosteen pericarp powder is then ready to be either packaged for wholesale purchase or ready to be shipped to be either encapsulated or used for other types of Faro mangosteen products.
