Shungite is for EMF. Emf is ELECTRO MAGNETIC RADIATION. Shungite absorbs this crap. Elite Shungite is for water purification. A book called “Dancing with water” has duplicatable tests that show that elite Shungite removes not only fluoride, but even trace amounts of radiation, pesticides, chemicals, metals and even mercury! I would love to find a scientist that would work with me on independent testing. As you can imagine it’s difficult to find someone who hasn’t got Uncle Sam balls deep in their ass.
