Books on Herbal Teas & Medicines

There was a thread that was similar to this, but for recipes instead of books. Could you guys posts some book titles of some books that have good information for anywhere from beginner to advanced in herbology. I'd really appreciate it. :)

Also, does anyone know of any good books on essential oils? Herbs are a lot less expensive and more readily available, but I figure I'll start using oils eventually.
