These essential oil blends are convenient to have around the house and easy to apply. I use a combination of 5 different essential oils - grapefruit essential oil, rosemary essential oil, eucalyptus essential oil, lemon essential oil, sandalwood essential oil, all known to have disease fighting properties.
