Oolong tea contains not only catechins, tea polysaccharides and tea saponin which are common in green tea and black tea, but also some special functional components. For example, some oolong tea varieties are rich in methylated catechins, which have anti-allergic, anti-inflammatory, anti-oxidation, liver cell protection and blood pressure lowering effects.
