We are, in large part, and among many other things, an expression of the ecosystem of our bodies which include bacteria, virus, fungi and other parasites. Successful "detoxification" is really largely about bringing these microorganisms and the rest of our being into balance since most of them cannot be gotten rid of entirely in any case. In many instances we don't want to get rid of them as in the right amount they serve a good function. We are all made up of these things in different ratios by design, really.
