Disclosed is a gargle preparation which can remove viruses that are present adjacent to the pharynx without damaging mucosal cells in the pharynx. Specifically disclosed is a gargle preparation (63) which comprises hypochlorous acid (HClO) and sodium hydrogen carbonate (NaHCO3), has an effective chlorine concentration of 50 to 300 ppm, desirably 50 to 250 ppm, more desirably 50 to 200 ppm, has a pH value of 6.3 to 8 inclusive, desirably 7 to 8 inclusive. The pH value of the gargle preparation (63) can be kept as a whole within a range from 6.3 to 8 in which hypochlorous acid (HClO) can be present at a high concentration, by the action of sodium hydrogen carbonate (NaHCO3). Therefore, when the gargle preparation (63) is put in the oral cavity and the throat is gargled with the gargle preparation (63) for a few seconds to several tens of seconds, viruses present in the pharynx can be removed rapidly by the germicidal action of hypochlorous acid (HClO) contained in the gargle preparation (63) and the safety of the gargle preparation for the human body can be ensured by the buffering action of sodium hydrogen carbonate (NaHCO3). |
