Kutzen means cough in Austrian, and this echoes through many rooms during the cold months. Essential oils such as lemon, pine needle, ravintsara and thyme are just what you need! Simply add a few drops of the mixture to a humidifier (diffuser) - this way, dry heating air evaporates naturally. The all-natural oils can also be used on a fragrance stone or in a fragrance lamp. Cough, we have no problem!
