If you bought an essential oil at a great, cheap price, chances are it is most likely a commercial distillation–a commercial distillation with chemicals and pesticides. A high-grade therapeutic essential oil is typically expensive due to the large amount of plant material needed. Additionally, Organic or Certified Organic does not necessarily mean a therapeutic-grade essential oil, as 95% of all essentials oils are still distilled under high-pressure for the flavor and foods industries. In order to reach your healing goals, a high-grade therapeutic essential oil is a must (and organic)! Please also keep in mind that essentials oils are very powerful as they directly affect the Limbic System and can bring up some painful and traumatic experiences.
