TOFKAT (The Oil Formerly Known As Thieves) Essential Oil Blend is a blend of the highest quality varieties of Clove, Lemon, Cinnamon bark, Eucalyptus, and Rosemary. This blend is not to be confused with our Four Thieves Essential Oil Blend [EOFourT] which uses more economical versions of the key ingredients. A novel written in the early 20th century implies Thomas Jefferson was the first American to use a version of this recipe. The aroma is spicy and sweet; perfect for many finer aromatherapy and candle blends. Please note that this blend is concentrated; made up of essential oils only, no carriers.
