I first got interested in using essential oils when I was a teenager. I've learned about a variety of types of oils since then, but more valuably I've learned about having a very high standard for the quality of products I work with. Since oils are vaporized the importance of an impeccably organic product is drastic. My favorite company for essential oils is called Mantra! They have 7 that are a single ingredient: clary sage, eucalyptus, frankincense, lavender, lemon, peppermint, and tea tree. There are also a few blends that I really enjoy. ~Mantra Oils Can Be Found through This Link and You Get 25% Off~.
