Aged mandarin peel (chénpí, 陈皮)

Mandarin tangerine peels, after being sundried, are often used as a warming agent to help the functions of the spleen and stomach, and balancing qi. Like the citrus fruit itself, mandarin peel is also rich in vitamin C, and antioxidants are also found in higher concentrations in the peel, which means more fighting off of free radicals. You’ll most often find mandarin peels used in teas, as well as a flavoring in stir fries with meat.
