I learned about OP on this forum, was curious and went to their forum on curezone. I wish I had learned about it earlier and "practiced" it during the Master-Cleanse in order to protect my teeth from the lemonade, but... what I wanted to tell you is that it has been said to cure eczema. Here is a link to more info in case you are interested.
I have been doing it for a couple of days and am impressed with the results. My parents, mother 77 and father 80, have started as well and are very excited to learn about it. So simple a 5 year old can do it.
