The original Alkalol Nasal Wash was developed in 1896 by pharmacist James P. Whitters, using a unique blend of natural extracts and essential oils to dissolve mucus and provide invigorating nasal-congestion relief. Alkalol Saline Nasal Spray utilizes those same natural extracts and oils in a new, refreshing formula specifically designed to provide fast, convenient relief for dry and irritated nasal passages caused by colds, flu and allergies. Refreshes with eucalyptus, menthol and more. Moisturizes dry, stuffy noses. Comfort, daily relief. Doctor and pharmacist recommended brand for over 100 years.
