Legend has it that during an outbreak of bubonic plague in the Middle Ages, robbers stole from the belongings of the plague’s victims. The robbers, according to legend, “were spice traders and perfumers. To avoid the deadly plague, they put the magic of their essential oils to work by washing themselves with the infection-fighting liquid.” Their formula has survived because it is so effective. Referred to as Thieves oil, this all-natural blend makes a great non-toxic disinfectant. Add it to other cleaning recipes for a healthy, natural alternative to commercial disinfectants.
