Clay baths & Mercury

My wife has been dianosed as having mercury in her system, we are going throught a detox program but frankly it does not seemed to have helped her much, and she is getting really down about it.
She has been on a this from 9 days out of a month but can see no difference, would it be worht her trying the clay baths, and can they be obtained in the UK?
