Make sure when choosing an essential oil brand that you research their sourcing and quality. Look closely at the ingredients for hidden synthetic fragrances or processed carrier oils that can be found in cheaper department store brands. Ensuring that the brand is reputable and ethically sourced will also increase your essential oil potency.
There are several clean brands out there, but my go-to is doTERRA. For more information about the company and why I love and trust them visit Why doTERRA.
