 It's blessed by God so that if you use the black salt to put a line around your home, it will keep anything negative from going through the line. It acts like a kind of force field. You can wear it in a necklace. I have friends that, and my paranormal group in the UK, that they wear their word in a necklace, a cremation necklace, and it heats up when it's in the presence of negative entities and it protects.
