Legend has it that during the Bubonic Plague (1665-1666) there was a gang of thieves that would go from house after house robbing those afflicted by the disease. They were eventually caught and a judge offered leniency if they would divulge the secret of their being in contact with the ill without getting sick. The thieves were said to use a combination of herbs and spices that kept them safe from illness; and those herbs were the mixture Clove, Cinnamon, Citrus, Eucalyptus, and Rosemary.
