What is a recipe for saline nasal spray?
Another recipe for saline nasal spray uses 3 heaped teaspoons of iodine-free salt, 1 teaspoon of baking soda and 1 cup of boiled water. Mix the salt and the baking soda together before adding the water. If stinging occurs during use, make the solution weaker, advises the American Academy of Allergy Asthma and Immunology. Apply the solution to the nostrils using a rubber bulb syringe.
