I had better experience using clay packs, nanotized chorella and DHLA for chelation, and NAET to treat my allergies.
Something else that helped with the rashes in addition to the clay packs was to exfoliate the skin using skin scrubs with dead Sea Salt
I use a scrub with dead sea salts and essential oils and scrub my skin extremely hard to remove the top layers. This with the clay packs has mostly gotten rid of the rashes.
I think the rashes are from mercury or some other heavy metal in the detergents I use to use before I got sick. I also striped some wallpaper and did some sanding before I got sick. My hands are still bad and I wonder if it was mercury in the paint or wallpaper glue. They did used to put mercury in paint.

Needless to say, I only use natural products now and I'm not going to sand any old paint jobs...
Its still amazing to me that the ADA and many dentists maintain that Amalgams
are safe, but mercury has been elminated from almost everything else. I think they just want to avoid any lawsuits from people like you and me.
