This sounds like chelation,nonly in reverse...the metallic particles attach to the bacteria as opposed to the removal of metals from the blood.
Chelation is limited to certain materials. Lead is the main one. Chelation doctors say that it will bind to calcium also. I had 30 treatments and it helped me and others I witnessed their treatments. The doctor also said EDTA reduced inflammation of all types, so it actually worked on more than just lead, metals, and calcium. I witnessed people being restored with Sclerosis of the liver, Pancreatitis, Lyme disease, and others as it relieves inflammation. Chelation works on aluminum and arsenic and a bunch of other metals. They will take measurements of about 20-25 metals in your blood and urine and then take it again at the end of your treatment.
