>Green tea has caffine.
http://www.stashtea.com/caffeine.htmInteresting link. I had heard that "yerba mate", very popular in Argentina and southern Bolivia, has a content of caffeine, but I didn't know that guarana had caffeine, too - they sell a carbonated drink here called "guarana", which is delicious (from The Coca Cola Company) - but I am not sure whether it is just the flavor, or whether it actually contains the fruit.
Difference in opinions hath cost many millions of lives: for instance, whether flesh be bread, or bread be flesh; whether whistling be a vice or a virtue; whether it be better to kiss a post, or throw it into the fire... (from Gulliver's Travels)
