This is how I look at it. A person can get poisoned from something from the outside that causes a skin problem. I think, with me, it was allergies from something on the inside of me that was causing the problem. If you've got a lot of toxins on the inside, the blood isn't clean, the colon and liver isn't clean, there is stuff coming out of the tissues causing rashes, then that means the liver and colon need cleaning out so the rest of the body can clean out and the blood and tissues can clean out and get healthy again. If it's allergies, it means the liver is congested. Or there's so much junk laid down on the colon wall that the body is continually absorbing these toxins and adding to the whole mess.
Try cleaning out your body and see what happens. Go to Doc's website above, find out how to do it. There a whole lot of information on this forum on how we did it.
Then try to stay away from all the chemical poisons and the solvents the best you can.
