Yes, this book is not a directory. Nevertheless, it appears very clear by reading the introduction that it can not be. If you have some knowledge of homeopathic medicine and this will be evident if this is not the case ... buy this book !!! You will find the principles of this method clearly explained, precise and concise. I was profane and (except in case of arnica shot!) I discovered a method that suits those who wish to treat considering how they feel. with this book, I even find the treatment that was suitable for me to stop smoking !!!
