Oolong tea is a kind of partially fermented tea. It is partially fermented and contains unique levels of tea flavanols commonly referred to as catechins. Caffeine works by stimulating the central nervous system (CNS), heart, and muscles. Oolong tea also contains theophylline and theobromine, which are chemicals similar to caffeine. During the partial fermentation processes, small amounts of polyphenols are formed such as theaflavin. Oolong tea is used to sharpen thinking skills and improve mental alertness. It is also used to prevent cancer, tooth decay, osteoporosis, and heart disease.
