Throat infections can be prevented using the mouthwash “Retterspitz Mund- und Gurgelwasser”. After cleaning your teeth, add two to three dashes to a glass of water, thoroughly rinse the mixture around the mouth, then gargle with it. The antibacterial properties of the essential oils regulate microbial colonisation in the mouth and throat and keep it in balance. A healthy throat makes it more difficult for viruses and bacteria to attack. Gargling daily helps to prevent colds.
