Himalayan salt bricks are huge slabs or even blocks of salt made of pink salt, which itself is harvested from remnants of ancient salt deposits in the Himalayan mountains. These salt bricks are commonly cut into different sizes and are used in salt walls, salt caves, etc. or even as décor. Not only a beautiful addition to any home, salt bricks are thought to have a number of health benefits- from improved air quality, to stress reduction, and relaxation.
