In all cases, chemical free is best. However, you don’t have to buy organic oils to get the powerful effects of using essential oils on your person and around your home. Now brand oils are available on Amazon, and work just as well as a cleaner, freshener, and for keeping the body healthy. *Please note that unless your essential oil specifically lists on the label that it’s okay to ingest, do not add essential oils to your food or drink or consume in any other way.
