Thieves Oil comes from research about four thieves (The Four Thieves Vinegar ) during the 15th-century
plague who used cloves, rosemary, and other blends to protect themselves
while robbing plague victims. The men made a
concoction of herbs and essential oils in a base of vinegar and would cover
their body with it before they went out plundering! The herbal
ingredients were rosemary, camphor, wormwood, meadowsweet, juniper berries,
sage, cinnamon and cloves in a base of white wine vinegar. History records that the perfumers seemed to have an immunity against the
plague.
