It gets complicated, if you can't get all the Mercury out it finds its way to the brain and makes all much worse. So some would have warned and blamed Iodium.

I would add that to mimic the homeo one could use Trappers magnetic version. Alchemy or Ion adjustment is part of Homeopathy.
However the issue with Mercury and Lead still exists...
