I was suprised not to see a recent green tea thread here. Interestingly enough, as popular as green tea has become, justly so, there is even a more potent cancer fighting tea; 'white tea' is challenging green tea's lead. i've been drinking green tea for years now. generally, it has releaved my migraines, and settled my stomach. it has also helped concentrate. if you live in the united states, I suggest buying "bromely green tea - decaffinated" it has a very nice frothy taste, and is enhanced with *honey, not sugar.
