During the infamous Black Death that ravaged medieval Europe... Legend tells of a small band of Thieves who ransacked the homes and villages where, 'the plague had visited upon.' Yet these thieves were no ordinary thieves - for, although the plague was killing people like flies, the thieves possessed a miraculous ability to avoid the accursed affliction. Finally, after they had pillaged much of the countryside, they were captured, and brought directly to the King. The lore of the thieves had grown large, and in eagerness and desperation, the King demanded to know how they had avoided the wretched Black Death. The thieves divulged that they had all come from a long line of Apothecaries. Therefore, they had an intimate knowledge of the healing arts, and were familiar with a specific combination of plants and herbs that provided powerful protection against infections. They consumed, doused themselves with and wore these ingredients in their clothing. As a result, they did not succumb to the dreaded Black Death. Based on the legend of the 'Thieves,' but university tested for effectiveness, Thieves Essential Oil products contain a blend of pure therapeutic grade essential oils of Clove, Lemon, Cinnamon Bark, Eucalyptus and Rosemary.
