Germ Destroyer helps protect your children from seasonal threats that occur during the flu and cold season. Help everyone stay healthy or recover more quickly with this super blend! Germ Destroyer is as effective as Germ Fighter (one of our most popular blends) but is safer for young children. Each oil in this blend helps to support the immune system and respiratory health, including Rosalina and Black Spruce for congestion; Lavender and Marjoram for relaxation, and Lemon for a burst of energy.
