doTERRA are the only company in the world who are publicly sharing their 3rd party testing (on every batch of oil). Transparency is key as the essential oil inducted is unregulated, leaving approximately 86% off essential oils on the market to be adulterated or fake, even when they’re labelled as 100% pure.
Their testing shows all doTERRA oils are free from herbicides, pesticides, synthetic agents, contaminants, fillers, heavy metals, and more.
doTERRA source indigenously and where the plants best thrive. Therefore, there is far less need for intervention or usage of excessive resources.
