According to Chinese legend, tea was discovered accidentally by an emperor 4,000 years ago. All teas (green, black, and oolong) are derived from the same plant, Camellia sinensis. The difference is in how the plucked leaves are prepared. The leaves of the tea plant are used both as a social and healthy beverage. Green tea, unlike black and oolong tea, is not fermented, so the active constituents remain unaltered in the herb.
Green tea contains volatile oils, vitamins, minerals, and caffeine, but the active constituents are polyphenols, particularly the catechin called epigallocatechin gallate (EGCG). The polyphenols are believed to be responsible for most of green tea's roles in promoting good health.
Each vegetarian capsule contains 160 mg of standardized green tea extract with 96 mg of polyphenols, particularly EGCG, and 16 mg Coffein plus 145 mg Green Tea Powder and 145 mg Grape Seed Powder.
