Germ Destroyer helps protect your children from seasonal threats like those that occur during the winter. Helps everyone stay healthy or recover more quickly. Germ Destroyer is as effective as Germ Fighter (one of our most popular synergies) but is safer for young children. Specifically formulated for children ages 2-10. This synergy contains 100% pure, undiluted essential oils of spruce hemlock, marjoram sweet, lavender, rosalina, and lemon.
