Green tea containe caffeine
If you're concerened about caffeine in Green tea, here is the comparison chart. As you can see in this, green tea contains slightly less caffeine than oxidized tea, but much less than coffee.
The caffeine content of a cup of green tea depends greatly on the type of tea and how it is prepared. Iced tea can contain as much as 70 mg. of caffeine per cup, and even decaffeinated is not totally free of caffeine as you can see in this chart. (Notice: decaf serving size is per 1oz.)
Caffeine in green tea works slightly differently from the caffeine in coffee.The tannin in the green tea works alongside the caffeine, so caffein is absorbed more slowly unlike coffee.
