Yeah I know the caffeine content is pretty small, just of course can't help but wonder if it still might be having any negative effects at all lol I think the main thing is the good feeling I get from just the basic idea that whenever I buy/drink tea I know I'm doing it as a positive thing to try and be healthier.
I've never even liked the taste until a little while ago when I thought maybe if I made myself drink it, and it had been so long since I had even a single drink of any, that I would start to like it and now I actually love the taste :P
