Yes I have tried it. It is basically a three day apple fast with enemas.
It does clear up your skin but if you go back to eating the same way you eventually will get Acne
If you buy the book and decide to do it be very careful about eating very good before the fast and breaking the fast exactly as it recommends in the book (very slowly with liquids first etc.).
I broke the fast by eating lots of solid foods. Nothing too unhealthy but it was alot. Afterwards I broke out in a rash all over my body. It took weeks and alot of money paid to a naturopath to clear everything up.
I cured myself of my Acne
once and for all by going about 90% raw vegan and following a akalyzing diet and regimine. Check out the Ask Moreless: Ph Balance forum.
It takes a commitment but in a few months your skin will look amazing.
God Bless you and Guide you on your way to better health,
