thx Angel for your experience/info..I was told this is a great forum. I definitely agree. I take clay internally as I couldn't get in and out of tub myself for the last few years. I am at a point now that I feel I want to try (altho fear slows me down a little lol)I also have severe heat intolerance. I have done clay foot baths successfully when energy permits, so may continue doing that for awhile. Thanks for the links! kathy
