According to the long-told historic tale…. The use of thieves oil dates all the way back to the year 1413. The time of the infamous Bubonic Plague (aka The Black Death) that devastated a large portion of France. The Black Death spread like wild-fire among the citizens, and the doctors alike. It seemed impossible to be in the vicinity without contracting it, and at the time, the sickness really did mean ultimate demise.
During this time, however, four thieves were captured and charged for stealing from the sick and dying. The thieves never contracted the plague, despite the close contact with the Black-Death victims.
At this time, the crime these 4 men committed was punishable by burning alive. The judge was so intrigued by how these men had stayed immune to this terrible disease, that he told them if they shared their secret he would spare them of this punishment.
The Thieves told the judge their secret: they were perfume & spice merchants who were unemployed due to the closure of the sea ports and the devastation of the plague. They had prepared an essential oil recipe that when applied to their hands, ears, temples, feet & a mask over their mouths, kept them safe from infection. The judge stayed true to his word. The men were not burned alive, but instead they were hanged for their crimes.
Thieves Oil History of Black Death Doctor
From then on, the doctors who treated the Black Death victims put the herbal infusion on their hands, ears, temples & feet, and wore beak-like masks stuffed with cloths containing this special blend. The beak is how doctors got the long-lasting nickname “quack”.
