Table salt and the salt they spread on roads in icy weather is identical! It’s simple sodium chloride. Except road salt hasn’t been chemically cleaned, bleached and treated with aluminum – an anti-caking agent associated with Alzheimer’s and other health issues, like standard table salt. Mother Nature never intended sodium to be the polluted, chemical-laced or unabsorbable product found in table salt, sea salt or even other salts labelled “Himalayan.” Original Himalayan Crystal Salt® is a true superfood you can use for cooking and eating and contains all 84 minerals essential for superior health. Use with Kyocera’s advance ceramic grinder. Rust proof and has a hardness close to a diamond.
