If somebody ever tells you that you’re like a salt in their wound, don’t take offence right away. Instead, remember that salt was once worth as much as gold and grain. Additionally, it was very important in traditional beliefs. It’s still present in superstitions and proverbs. For ages salt has been used to make butter, preserve meat and other food, as well as was given to the cattle and used in the process of tanning animal skins. It was either mined or gathered from salt pans, which influenced its steep price.
