I had given up looking by the time I dismissed clay baths, foot pads, ndf, and so forth. I am not a biochemist or physician, and I have yet to see any allopathic detox protocol that directly addresses Cutler's approach and shows why its own method is superior. Until I do, I probably won't spend a lot of time on them.
Getting mercury out of the blood is not hard. Your own body can lower blood mercury through sweating and so forth. It is the semi-permeable membranes on the cells in the CNS and endocrine system, as well as some other organs, that make mercury so problematic. And unlike Cutler's approach, I have not seen any other protocol that addresses that so directly, unless it is to make a tacked-on claim.
