Seed to Seal Science Pillar Question of the Day – Chris Bowerbank YL
Q: Does Young Living test essential oils from other companies?
A: Yes. Young Living R&D periodically purchases essential oils that are for sale at retail stores, online/Internet stores, etc. to help us understand and evaluate the quality of products available on the market, and to confirm our position as the World Leader in Essential Oils. We test the oils in our R&D and Quality Control (QC) laboratories and compare the results against both our #youngliving #seedtoseal quality specifications and an authentic Seed to Seal essential oil standard.
For example, we purchased two #peppermint essential oils from different retail brands. The first bottle was labeled as mentha piperita, “100% pure essential oil”, and “GC/MS tested”. The second bottle was also listed as mentha piperita, for aromatherapy use, and an “essential oil blend”.
What we found:
Both samples failed several peppermint specifications
Retail 2 sample failed aroma testing
Both samples failed high for lead content
Retail 2 sample failed high for arsenic
Both samples likely included adulteration with corn mint
GC/MS testing alone is not indicative of essential oil quality
Heavy metal testing is an important quality test
An essential oil purchase should not be based solely on price
