One thing you can say about this product- it is very full of information in a relatively short book. But, I would recommend it only to those who have at least a basic understanding of both Western and Chinese/East Indian herbalism to get the full effect (which is its intended audience I believe). Though the book does explain most of what it states, this knowledge is necessary to fully appreciate it. It reads like a textbook more than anything, which is great but may not make it a "page turner" for those that don't have this knowledge.
This is an AMAZING handbook, and it explains energies of herbs (I believe over 400 of them!), some history, preparations, organs herbs effect, dosage, parts used, the properties of herbs, and even the methodology behind it all, without going in to too much detail. I especially appreciate the beginning, where he goes into food therapy, the types of preparations and why it matters, the eight methods of therapy, as well as the nature of herbs in Chinese, Western, and Ayurvedic systems and the roots of it all. Excellent! Also, extremely useful appendix/glossary!
