The essential oil industry is unregulated. That means fraudulent claims of purity and potency often go unchecked. This leaves the consumer confused because, “Someone should be checking these things right?!”
DoTERRA has set the bar high for the industry with its Certified Pure Tested Grade (CPTG) standard. It measures purity and potency in essential oil production in these four areas:
• Plant sourcing
• Production integrity
• Comprehensive testing
• Packaging and storage
DoTERRA tests its essential oils more than any other producer in the industry. Their uncompromising standards have enabled research that’s reshaping how the world views essential oils. doTERRA products are studied and used in hospitals, labs, and clinics across the globe because of this standard.
You can learn more about each of doTERRA’s testing methods in the article linked below! Every oil batch is tested with these methods, so you can confidently use these tools in your home every day.
