I once went to a well-known Naturopath who said my cold hands that turned blue in the cold were caused by mercury poisoning from my amalgams. He also said that using a zapper on my wrists had caused further damage.
I feel much better since getting my metal fillings removed. Before that, I felt that I didn't have a hope of getting the metals out of my body. I've used cilantro and chlorella to help get the mercury out.
