Abstract
Abstract A formulation of a mixture of a salt, preferably sodium chloride, and ascorbic or isoascorbic acid, when mixed in proportions by weight of 90-92% salt and 8-10% acid and dissolved in a volume of water providing a solution concentration (weight per unit volume) of 4-6% salt and 0.3-0.6% acid provides an effective oral rinse useful in bathing and cleansing mouth and throat tissues to relieve and prevent mouth and throat irritations which accompany colds, influenza and periodontal disease.
