Sore Throat Remedy • A common remedy for a sore throat is to gargle with salt water. This is because some of the pain associated with a sore throat is caused by swelling of the throat tissues, which contain water. Salt water has a lower concentration of water than the throat tissues do, so when a person gargles with salt water, water moves by osmosis from the throat tissues into the salt water. The loss of water decreases the swelling and relieves some of the pain.
