“To ease the discomfort of pharyngitis or postnasal drip irritation from allergic rhinitis, suggest a baking soda solution as an alternative to saltwater. At the first sign of a sore throat or scratchy throat, combine one level teaspoon of baking soda in one cup of water and gargle, rinse, and spit 3-4 times daily. The solution changes the throat’s pH, creating an environment that is less conducive to bacteria and virus replication.” (Cerreta, 2009, p. 44)
