Carol - I didn't have enough time this morning to do a search for a reference to this but the rash comes as a result of candida die-off and the body is getting rid of the debris.... drinking extra water is supposed to help. The skin is the largest detox area - all waste products go through the skin - and kidney and bowels...but for some reason, a detox rash is very common with candida.
I found that a hydrocortisone cream helped alot. Hated to use it but none of the other natural things I had seemed to help.
I have one favorite spot that gets the rash on the inside of one ankle and the last time I did a liver cleanse, I got a huge red, itchy rash on my chest in the area of the thymus gland. It was ugly.
If you do a google search on candida detox rash there are alot of hits that you can investigate.
