A blend of the finest Clove, Lemon, Cinnamon, Eucalyptus, and Rosemary. Developed according to the legend about the four thieves in 15th century England who used these and other aromatics to protect themselves while robbing plague victims' graves.
Four Thieves Oil blend is my favorite! I usually diffuse it whenever it's 'cold & flu' season. I also wear a drop in my diffuser necklace (also bought at Fountain Alley). I mix a few drops of it with some carrier oil and rub on my feet before bedtime to keep my immune system strong.
