Alkalol is a nasal wash and oral rinse. Alkalol dissolves mucus, cleans and moisturizes the nasal airways, and provides relief to agitated sinus, nasal passage and throat tissue. It is an alkaline saline solution that includes a mix of menthol, camphor, eucalyptol, thymol, benzoin, and oils of wintergreen, spearmint, pine, and cinnamon, as well as potassium and sodium salts. First formulated by James P. Whitters in 1896 in a small laboratory above the A.J. Barker pharmacy in Taunton, Massachusetts, Alkalol is one of the oldest over-the-counter pharmaceutical products sold in the United States.
Alkalol is essentially alcohol-free, containing 2/100 of 1% alcohol by volume. The product is intended for use as a nasal wash to relieve symptoms of sinus infections, allergies, colds, nasal congestion, post-nasal drip, rhinitis, and respiratory problems caused by dust, pollen, mold, pollution, and other irritants. Alkalol is also indicated for regular use as an oral rinse and throat gargle to break up mucus and treat sore and dry throats, laryngitis, tonsillitis, tonsilloliths, mouth sores, and throat irritation caused by allergies and post-nasal drip.
