• dissolving a flavoring agent in the liquid solution to create the preventative gargle;
• storing the preventative gargle in a container for use between the administrations;
• gargling a gargling dosage of a preventative gargle at the oropharynx of the asymptomatic patient;
• and
• repeating the gargling twice a day for the several consecutive days to prevent the onset or progression of COVID infection in the asymptomatic patient,
