I drank a lot of SleepyTime and Tension Tamer teas during my first month of sobriety. They helped a lot with anxiety and relaxation. I didn't care and still don't about a tea carried in the grocery store - Chamomile and Valerian in the one and Eleuthero in the other. Oh, and catnip
Green tea and white tea has a little caffeine, not much, but enough to keep me away from it in early recovery. I was too jangled.
Can't you do some online research? A cup of tea has so little of the herb/flower in it. I was concerned with staying in my skin and it was the legal, non addictive natural way to do it.
