I have a lot of books about body cleansing and alternative healing, but this one has information, which I never heard before like zapping or removing gold from the body for obese people. Also I think author is a little bit abscess about not using any metals even stainless steel, but she does recommend using plastic; and it is a little bit confusing about usage of filters. But I gave this book five stars anyway, because I think, that it has extremely valuable information and it is one of must have books.
