This book is everything the first edition should have been, and more. I think the other books with this title are trying to cash in on this book's popularity. This book lists the best herbal antibiotics in the world, parts used, the preparation and dosage, the properties (i.e. actions and which bacteria each is effective against), side effects and interactions, traditional uses, scientific research, and much more. There is no other single book on herbs which is at all comparable to this and his other masterwork, HERBAL ANTIVIRALS (also second edition).
