Sore throats, toothaches, postnasal drip, bee stings, mosquito bites, painful gums, poison ivy, and poison oak are some of the ailments for which salt has been prescribed. Modern science doesn't endorse all of the traditional uses of salt, but this article offers a picture of the seemingly endless healing qualities salt may have.
Sore Throat: The simplest remedy for minor sore throat pain is a warm saltwater gargle (no matter how much you dislike the taste!). Just add 1 teaspoon salt to 8 ounces warm water, and gargle several times a day. See a physician if the sore throat persists longer than 3 days or is accompanied by a high fever.
Burns or Injuries: A severe burn in your mouth from eating something very hot can be relieved by rinsing with saltwater every hour or so. Use 1/2 teaspoon salt in 8 ounces warm water.
Biting the tongue or cheek can result in a large amount of blood but is rarely serious. To help ease the pain, rinse mouth with 1 teaspoon salt in 1 cup warm water.
Gums: Swish with 1 teaspoon salt in 4 ounces warm water when gums are painful. If you have an abscess, the salt will draw out some of the infection. Any gum pain should be treated by a dentist as soon as possible.
Toothaches: As a temporary remedy for a toothache before going to the dentist, rinse your mouth with a mixture of 4 ounces warm water, 2 tablespoons vinegar, and 1 tablespoon salt.
Add 1/4 teaspoon salt and 1/4 teaspoon baking soda to 8 ounces warm (not hot) water. Gargle with the mixture 3 times a day to ease your sore throat. If pain persists longer than 3 days, contact a physician.
Nose: Make your own saline nose drops to use for controlling annoying postnasal drip. People with sleep apnea, a condition that involves a dangerous interruption of breathing while asleep, may also want to try these drops to help keep nasal passages open.
