I think it is ok.... im having a cup a day..it is so relievieng
Ive heard chamomile is ok and helps with insomnia. If you have hayfever/a sufferer, you may need to steer away from it though.
* herb with NO actual tea leaves- sorry!;)
As far as I know, chamomile does not contain caffeine, since it's a herb and actual tea leaves. So I'd say you can have as many cups as you want. Just check out labels and make sure there's no caffeine. If there is, up to 2 cups a day tops.
