Himalayan Pink Rock Salt has been unexposed to toxic pollution from the air and water, therefore it is considered as the purest salt on earth. The mining process still has not changed from the old traditional methods and there is absolutely no use of explosives during the process. This salt is 100% pure with no added chemicals or anti-caking agents like that of regular table salt. Table salt also contains artificial Iodine and other additives that may be described as harmful, but after switching to Himalayan Rock Salt for everyday use, it will serve a great purpose.
