Tea, Caffeiene

[theBruiser500]

How much caffeine is there in green tea? I think there is a relatively small amount when drinking it, but how about eating the tea leaves? When I was in China they said they don't drink the tea, they "eat the tea" because I'm guessing if tea is good for you, eating the tea leaves is and they said they didn't put any chemicals on the leaves so they are okay to eat. How much caffiene is there if I eat the tea leaveS?
