This essential oil blend of lemon, cinnamon, rosemary, clove, and eucalyptus 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. This led to a deeper inquiry in court after they were caught and charged. The magistrate offered them a deal, their secret for a reduced sentence. Taking the deal, they told stories of their herbal knowledge and their powerful medicinal properties when combined in certain ways. This specific herbal blend that they had created, concocted from aromatic herbs, was HIGHLY EFFECTIVE in killing all of the airborne bacteria. In 1997, Weber State University did a study that found this essential oil blend to have a 99.96% success rate at killing airborne bacteria. We don’t know whether or not this “thieves” story is true, but the essential oils are truly antiseptic, antiviral, antibacterial, and anti-infectious. They will stimulate the immune system, circulation, and respiratory system, and help protect against the flu, colds, bronchitis, pneumonia, sore throats, cuts, and more.
