I use both natural mineral salts (sustainably harvested from Nan near the Laos border) and various clays in my skin-bodycare products and am a devotee of both. Salt water is a number one for soaking!! Currently working on a natural-mineral-salt-rice-milk bath soak. :) Love that you have found healing from this itchy-horrible "thing" (probably mostly by lowering your stress). Lovely post, Alex. x
