Query: DONT WASTE YOUR MONEY!!

I bought this book, and I am sorry I did. This is NOT a cure for all Cancers. My Mother has Cancer in the spine, and she followed the directions in this book exactly for 3 weeks, and its done NO GOOD. I tried to contact several people who left a review that this thing worked and none of the emails are accurate. Don't waste your money!!
