Finally a comprehensive book on the subject! We feel great knowledge of the author and his longstanding practice of incense. This book is not just for lovers and users of incense. Her beauty makes it a "book-object" that can be offered without blushing! Beautiful photos of plants and drawings illustrate this book with chapters make us travel from one continent or culture to another with happiness. Since the caveman to today, North Europe to Japan via the Americas, the trip is informative and exquisite.
