I really like the "St. John Ambulance Official Wilderness First Aid Guide" published by McClelland & Stewart Inc. (ISBN 0-7710-8250-9). This is the one that we use as the textbook for our First Aid in the Wilderness course. It's available through Amazon for $14.99, which I presume is US$. (My copy has a list price of $19.99 Cdn.)<br><br>IME, Most First Aid books will not discuss traditional or herbal medicine. You should look for a specialized book on the subject, something like "Edible and Medicinal Plants of the Rocky Mountains" from Lone Pine Publishers (couldn't find it on Amazon, sorry). Check these out carefully, though; a lot of the authors of this type of publication are a little gullible IMO, and will parrot off any old wive's tale as if it were gospel truth.
