Oolong tea is a traditional Chinese tea made from the partially oxidized leaves of the Camellia sinensis plant. It is fermented for longer than green tea, but less than black tea. Oolong tea contains caffeine, which affects thinking and alertness by stimulating the central nervous system, heart, and muscles. It also contains vitamins, minerals, amino acids, and beneficial tea polyphenol antioxidants. Some of the main antioxidants in oolong tea are theaflavins, thearubigins, and EGCG. Oolong tea also contains L-theanine, an amino acid shown to have positive effects on relaxation and cognitive performance.
