Chamomile is one of those herbs that is highly versatile. It is my favorite nervine herb because it is so gentle. I know that I can drink it in the middle of the day to unwind and I won't need to take a nap, unlike the stronger nervine herbs like skullcap.
But, there are also other things that I use chamomile for. Here's a list:
hair rinse to bring out light highlights
gentle pain relief
tummy aches and other stomach problems
My favorite way to take this is with a tea. If you can find a brand from Germany, they have the best chamomile flowers - I can smell them blooming!
