Evolution Himalayan Crystal Salt is pristine, pure and 100% natural and raw. It is the most beneficial and cleanest salt available on our planet. Over 260 million years ago, a vast primordial ocean covered the Himalayas. The salt from the unpolluted ocean was preserved as large crystal formations in the foothills of the Himalayan Mountains, making Himalayan salt absolutely pristine and natural, identical in composition to the ancient primal ocean.
