The story of the Four Thieves essential oil is like a Deep State kind of story back in the 1500's.   "Thieves oil is an essential oil blend based on a story from around the 15th century when the bubonic plague was running rampant through Europe and Asia. Four thieves from Europe, who were notoriously robbing the infectious dead bodies of all their possessions, miraculously never contracted the highly infectious plague."  It is a GREAT germ killer.
