Eli5: how did humans get salt before modern means of transportation

610 views

The human body needs salt to function properly, but surely First Nations of the prairies, people of central Africa or of Central Europe, from the Mongolian steppes and from other landlocked places, couldn’t have access to salt marshes. So where did they get it from?

Things like salt (spice trade) were exactly what started large scale international commerce tho. So it’s kinda like asking how people got around at all before modern transportation, they were working on it.
