For 3,000 years, before it became a social and recreational beverage, tea was used as a medicine and wisely so it would seem. The most promising of these is catechin, a tannin derivative that gives tea its astringency and is common to many plants such as grapes, berries, and ferns. Catechin compounds are found in the leaves of both green and black teas, but green teas have much higher levels of catechin than do black teas. Black and green teas differ only in how they are processed. Black tea leaves go through a fermentation process that gives the tea its characteristic dark color and tart flavor.
Catechins defeat cancer in at least one of three ways.
First, they can prevent the formation of carcinogens, second, they turn up the body s natural detoxification defenses, and finally, they suppress cancer promotion. All Rights Reserved .
