This book is one of the very best field guides to medicinal herbs. A must have for serious herbalists of all levels. The photos are absolutely spectacular! The one flaw: the book is not easy to use as an identifier unless you are pretty sure of what the plants name is already, because the book is organized by name mainly. But, if you know the name of the plant you are looking for then there is no better book. Email the publisher telling them to reorganize this book so that it is more versatile as a field guide. The planet needs this book. I'm serious, it's that good.
