this cleanser is the best thing that could happen to any individual. I had poor blood circulation, and varicose veins. After a 21 day fast I was relieved of the tightness in my less the varicose veins had gone down and there was no pain at all. The book is so excellent in details and easy to follow instructions anyone would be able to get involved in the process. I found the book very informative as far as foundational information was concerned(like the medical information on lemons and the building blocks of protein and how the acids work in our bodies). The book is sooooooo (smile) valuable. I bought many of the books and share them with people wherever I find the need and people are open to receive. We as people have to be willing to let go of some of the things from tradition (ham hocks, chittlerings, bacon, etc.) and eat what is healthy for our bodies and leave our taste buds out of it. I would recommend this book to anyone as I speak I am now on the cleanser diet I plan to go the whole 40 days, I might stop at 34. I have been on 24 days. I hope to be consistant with my cleansing.
