Herbal Teas?

Okay, so I've come to the conclusion that I really should start drinking more herbal tea.

I know they're good for you and that some of them are really nice, but I don't know which ones to try.

My mom's friend is a dietician and recommended that I drink both peppermint tea and chamomile tea on a regular basis, because I get a lot of headache and stress a lot etc. I wouldn't have a clue what brands though.

Any suggestions? Are there any particular herbal teas that people like to drink? And are there any particular brands that people like?

So clueless!
