Essential oils of: Lemon, Clove, Eucalyptus, Cinnamon and Rosemary. Legend tells this germ fighting blend was used by robbers and thieves during the medievil times to protect themselves from the plague and other diseases. 1997 Weber State University study showed the oils to be 99.96% effective against airborne bacteria.
In a small spray/spritz 2 oz bottle I poured in purified water aand added about 6-8 drops of Germ fighter Synergy oil for hand sanitizing . You may go as high as 8 or 10 pending upon your desired concentration. I use this as an equivalent to YLO Thieves. I use more drops used because it is not as viscous as the YLO product. I also add to cleaning solution for home use.
