The instructions for the clay baths recommend that they only be used once per week and that especially sensitive individuals should ramp up the amount of clay they use over several weeks. Ostensibly, it is because the skin is such an incredible organ for releasing toxins from the body that you can over-encourage the body to dump toxins. And thus, you'll experience the effects of these toxins (effects will vary by individual). This scenario reminds me of the arguments by Cutler regarding the frequency of chelation therapies. For those who haven't read the text, he maintains that in order to protect the body, chelators have to be taken on a regular basis during chelation campaigns in order to maintain a stable blood concentration that mops of loose mercury. Isn't it reasonable to use this rationale for clay baths? If clay baths clear toxins and once temporarily cleared the body releases more, why not take clay baths more frequently? The frequency could be determined by the individual based on how she feels (I know I can feel it when toxins build up and mercury is loose in my system: scattered unfocused brain, painful ileo-cecal valve, cold feet). Another possibility is that either drinking clay solutions (Sonne makes this and is available at health food stores) or taking algin (I've not tried this) will bind toxins released by the liver into the bowel and prevent re-absorption. Any thoughts?
