Mercury can be worn in amulets, sprinkled on the floor, or added to an oil lamp as part of some Latino and Afro-Caribbean practices including Santeria, Palo, Voodoo, and Espiritismo, according to the EPA’s inspector general.
Some practitioners believe that the mercury, which forms tiny droplets in liquid form, can attract love, luck or riches, and evil, the report said.

A...trick in full play these days comes from voodoo. Voodoo is in essence the control and manipulation of people by means of elemental mercury poisoning."

"The ore of mercury is used in many of the ceremonies and is prescribed by the witchdoctor for hanging around the neck in a sack as an amulet, placing around the persons environment in the home or car, and even ingesting it or soaking in a bath with it, which is the same thing as eating it. Mercury outgases in all of these things and is taken in through the lungs as well."

"Being a powerful neurotoxin, mercury creates a state in the adherent which makes them highly susceptible to suggestion and other mind control techniques."
