No, I've not heard of it and don't have an educated opinion though....I hate to say it but I asked Andy Cutler(!) about homeopathy for metal/mercury detox a while ago as I thought it might be safer option. He said no he wouldn't recommend it and despite claims, if done improperly can make you worse.
Has this product been used successfully before (did your practitioner tell you) or are they experimenting on you?!
Sorry to put another downer on this chelation issue!
