7 Amazing Benefits of Oolong Tea

About Oolong Tea

Oolong tea is a traditional Chinese tea that is commonly consumed in China and Taiwan. It is made from the leaves of the Camellia sinensis plant, the same plant that is used to make green tea and black tea. The difference is in the process of oxidation that makes them into black tea, Green tea, or oolong tea.

Green tea is made from fresh leaves. Black tea is produced by crushing the leaves to enhance oxidation. Oolong tea is created when the leaves are wilted in the sun and bruised to create partial oxidation (1)
