What are some good resources for making your own herbal teas?

I’d like to start making my own herbal teas. I have some great natural food stores around that sell a huge selection of herbs/spices/oils and I’d like to take advantage of that.
I’m interested in websites, books, pdfs, etc with good recipes. I know you can combine herbs with similar health benefits to make some tea, but I’m more interested in new/unique flavor combinations that I haven’t tried in premade teas.
