Take a look at Dr. Cindy’s site, Armageddon Medicine. She has all KINDS of great info about first aid, medical issues, etc. and its FREE.
She also has a couple of books she offers for sale and if you’re in her neck of the woods, check out her classes. Dr. Koelker is a frequent guest on The 21st Century Homekeeper Radio program where we talk about all kinds of medical issues as they relate to prepping and to daily living.
