Poor thing! Hope you're feeling better. I agree w/ searsmom about the taste of german chamomile. Not too good. I am going to plant roman chamomile to try it this spring!
I read that chamomile helps with stomach upsets and calming the nerves. So, I tried it when I had an upset stomach and it worked, but I didn't feel any calmer
If you are having trouble sleeping, try valerian. It really works. Some herbal teas are a blend that have valerian in them. One I can think of is tea for sleep from good earth. It has valerian roots in it, along with lemon balm, lavender and rosemary. If you are really having a hard time sleeping, try valerian tincture. It really smells bad, but does the job.
There is an herbal blend that I like the taste very much. It is called sleepy time from celestial seasons. I can sleep anywhere, anytime, so I drink this blend for the taste
