AllenS was talking about his green tea in the comments and I have a lot to say about it. I have to limit my coffee consumption as I have to lay low on caffeine because of my bum ticker. So I have been doing a lot of herbal tea and have learned a lot about it.
Now processed teas that you buy in tea bags are not washed before they are packages. So they often contain dangerous levels of pesticides in each teabag. In addition you know what is one of the most dangerous ingredients in your typical tea bag? Fluoride. This is what stains your teeth bags. It is also really not good for you in general. The fluoride added to drinking water is minuscule compared to the natural fluoride content of many teas.
Even worse is the way they treat the tea bags. The big time commercial tea bags are treated with epichlorohyrin which is a plastic that helps to keep the bags from breaking. The problem is that epicholorohyrin can potentially break down in water to be released into the water. Water with high levels of this toxic chemical can cause severe stomach pain as well as a highly increase risk of cancer.
