In writing this book we are exploring eating wild plants — some of which have poisonous look-alikes or poisonous parts — not to mention using them for medicine.  So we really wanted to get our facts right — not just repeat things we’d heard somewhere or the other.  That meant reading hundreds of research papers, book chapters, medical texts and historical documents.  They aren’t all represented here, but the ones which back up particular assertions in the book are.  If you want to read the papers, you can find most by searching for the titles on  (Most ask for payment to read though, unless you’re lucky enough to belong to a university.  See this resource of free journals.)  The references are broken into sections and in order of their use in the book, so keen fact hunters can match an assertion with a reference, but feel free to ask us if you need help. 🙂
