No, it is not. Buy a cheese grader and use the broken pieces of Himalayan salt to spice up your dishes or break them into fine pieces and place them in a salt grinder. The salt from the blocks and the edible salt are exactly the same. If the block is fairly new, you can also use the broken pieces for a mineral rich bath. You can even save the pieces and place them into a soothing foot soak when need be. Or get creative and place the fine grain salt into a fabric pouch and place on your forehead for headache relief.
