There are more than 2,300 named varieties of this shrub. Camellia sinensis is the variety which is the source of green, black, and Oolong tea. Even though all three teas are made from the leaves of the same plant species, their chemical content and flavors are very different due to different fermentation processes. Green tea leaves are dried in hot air, then pan-fried to stop the oxidation (fermentation) process, while the leaves of Oolong tea are dried in full sunlight, and are partially oxidized. Black teas leaves are fermented in cool, humid rooms. Green Tea has been a beverage for thousands of years, yet the documentation of the potential health benefits of this tea have been recorded only within the last couple of decades. Polyphenols, the substances known to possess strong antioxidant, anticarcinogenic, antitumerigenic, and even antibiotic properties, are abundant in Green Tea. - - - - - - - - - - - - Back to Top - - - - - - - - - - - - Green Tea Uses & Scientific Evidence For There is a growing body of evidence that suggests that regular consumption of Green Tea can reduce the incidence of a variety of cancers, including colon, pancreatic, and stomach cancers, and in fact, many people drink Green tea daily for cancer prevention.
