The History of Salt
Salt was in use long before recorded history. Since the dawn of time, animals have instinctively forged trails to natural salt sources to satisfy their need for salt.
Ancient man, the hunter, obtained his salt from eating animal meat. As he turned to agriculture and his diet changed, he found that salt (maybe as sea water) gave his vegetables the same salty flavour he was accustomed to with meat.
Over many millennia, he learned how salt helped to preserve food, cure hides and heal wounds. Nomadic bands would have carried salt with them and traded it with other bands for different goods.
