When I ordered this book I thought that it would be helpfull to do my job. However, the book's contents are just amazing. It is well structured and it gives all the details I required to enhance my knowledge on the topic. So far I am still reading the book, since it takes time for me considering how busy I am, but the most important thing regarding this book is the fact that I have been able to combine the issues dealt with in this book with my previous knowledge of homeopatic medicin. This has been the most valuable investment I have done in the last 5 months.
