Here is a reliable way to know if an essential oil is pure (and why you should care).
Back when I first began using essential oils as a massage therapist, I had a wake-up call.
I had heard that adulteration (the practice of adding substances to bottles of essential oil) was unfortunately common in the Aromatherapy industry. And that it isn’t always easy to know if an essential oil is pure.
But I used essential oils from a company that I knew and trusted. I wasn’t worried about adulteration.
