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

616 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?

Lol Salt can also be mined in mines… We have few of those in Poland, including oldest one here in Wieliczka. This was very expensive good though, king had ownership over it.
