Looking for a little help here. Here's what I'm looking for. I seem to always have back and spine pain. Sometimes worse than others. I don't like taking a lot of the over the counter drugs , that don't usually do much, except eat up your liver and other bodily organs. And the doctor prescribed stuff that is out today will work, but we all know about the addiction rates for this stuff and I don't want to have to deal with that . So , I've looked into the possibility of natural remedies. I also want to start trying these natural weeds for food sources as well. So I'm looking for suggestions for a good book that I could carry in field to help with identification and uses. Now, I've found online one that is a food source and a pain reliever. It's called Prickly Lettuce. Now there are different varieties of this plant, but I've not found if the other varieties carry the same properties. The Prickly variety has kind of a thorny spine. It's also called by other names, and one of them is Opium Lettuce. Now don't misunderstand me here, I'm not looking to abuse these plants for illegal purposes. So I'd like a book that will tell all the uses for these plants and how to get the intended results, food sources, teas , medicinal. How to prepare them, harvesting times, etc. My grandmother used to cook up a few meals with different wild weeds years ago , but I don't remember what these foods were. I'd quality is a must, I don't want to get the wrong one. Also if it would tell what plants to stay away from and why, but I've read that these poisonous plants actually have some good uses as well if used correctly, and that could come in handy as well . Thanks for all your help and suggestions and your own personal experiences and recipes in this area. Also , I'm in NC, so the plants that would be native to my area would be especially helpful.
