Black Lava Salt is sea salt combined with activated charcoal. Black lava salt is used in magick to absorb and trap negative energies. Salt is used by many to absorb energy, and charcoal is well known to absorb toxins, so the two make a natural pairing. Black Lava Salt is used medicinally to absorb and flush toxins from the body. Black salt is usually added at the table, rather than during cooking. Different types of charcoal are used. For example, Hawaiian Black Lava Salt is made from charcoal from burning coconut shells. This is said to add a bit of a smokey flavor to the salt.
