I bought this book one month ago and this is an excellent book. I am a fan of the natural products and an expert in selling all kind of nutritional supplements but, I didn't understand a lot about bioregulatory medicine. I knew the concept but, moroever, I wanted to learn more about their philosophy. I was amazed when I opened it: it has only 160 pages but it has a lot information. The writers are quite professional because each theme is explained using biochemistry, scientific evidence and a lot of maps (which are very explicit, accurate and visual). Now, I understand why the products which are based on bioregulatory medicine work so well. I would definitely recommend the book to all the readers who want to know more about this complementery medicine.
