The Healing Crystal First Aid Manual by Michael Gienger
This is a book that we use a lot ourselves, and keep with us at shows as a reference volume. The cover states that this is "a practical A to Z of common ailments and illnesses and how they can be best treated with crystal therapy," and this book really does exactly that. Plenty of information about crystals, putting together home remedy kits, great references, once you have this book you'll reach for it again and again. Paperback with more than 300 pages of well-written text. Certainly not a substitute for professional medical care but indispensable for the crystal healer.
