dōTERRA is not only offering life-enhancing benefits to the world through their essential oils. They are also offering those benefits to families living in poverty.
When an oil is CPTG it is the safest, purest and most beneficial. Experienced growers from around the world gently and skillfully distill oils from plants that have been patiently harvested at the perfect moment for ideal composition.
This superior quality is easily recognized by experienced essential oil users. doTERRA’s™ oils are all CPTG.
Many companies and products claim to have essential oils that range in price and quality but they don’t use 100% pure essential oils. The products often have fragrant synthetic chemical substitutes to replace the more expensive essential oil extracts.
Currently, there is no standard regulatory mark that represents if an essential oil is pure. The CPTG mark is doTERRA’s own internal standard for sourcing and testing 100% pure botanical extracts. This CPTG mark guarantees that doTERRA’s oil extracts meet high standards for material composition, purity and accurate product labeling.
doTERRA’s essential oils do not contain artificial ingredients that would dilute the properties of the oil.
It seem to me that there are no better essential oils than that of doTERRA™.
