Rub it in

What is the origin of the idiom 'rub it in' as in "I know I was stupid; you don’t have to rub it in." ?
  

Top answer

My guess is that it comes from the concept of rubbing salt in the wound. It hurts, but it used to be a common natural medication for aiding in the healing of open wounds. It still is used for sore throats by many (salted water).
