Thieves® Roll-on is a powerful combination of Clove, Lemon, Cinnamon Bark, Eucalyptus Radiata, and Rosemary essential oils, pre-diluted for quick and easy application on the go. Formulated by Young Living founder, D. Gary Young, this blend was created from research recorded in the archives of the British Museum library about a group of 14th century European perfumers and spice traders who rubbed oils on themselves while they robbed the dead and dying. The first essential oil blend to be scientifically evaluated in a university research laboratory, Thieves has a rich, spicy aroma, and is a key ingredient in our Thieves Home Collection – your go to for an invigorating clean and healthy home.
