Medicinal Plants of the Desert and Canyon West - Michael Moore
I went to his school in '94 when it was in Albuquerque. His other books about western medicinal plants are the best there are. He was one of the best American herbalists there was.
Thanks! I’ve been feeling an Amazon order coming on, and I think I’ll get this book, and probably Kane’s book about edible plants, too. We harvest tunas most years in the fall, and make jelly from them (or syrup, if the jelly doesn’t set). Messy, but fun.
