this book is perfect, very easy to carry and use - The explanations are very clear, with countless details. Revenues, for the ones I've tested are excellent. It's a great idea to have added revenue - I will put a damper, so 4 stars, too bad there is not poisonous plants that could be mistaken for good. When you are in nature, the question always arises at the time of collection for the novice that I am. But I have already tested seven plants and all is well - Furthermore, all plants of this book are very common. In part 2 I have never seen - So very good book, I recommend to beginners. Great buy
