Here is a quick list of what should be on a label of high-quality essential oil.
Botanical Name: The exact botanical name of a plant in Latin name gives you very important information about the oil that you're buying.
For example, Lavender – is not enough! There are few types of Lavender, the most popular is Lavandula Angustifolia and it is twice the value of Lavandula Latifolia.
Place of Origin: What country was the plant grown in? This has a huge impact on the quality and biochemical composition of the oil. Where the oil comes from is also directly linked to its value i.e. A French Lavender has a higher value than a USA Lavender.
Cultivation Method: How was this plant grown and harvested? It's important to know the farming methods used by the farmer who grew the plant that produced your oil - the integrity of an essential oil rests greatly on the cultivation method.
Batch Number: This number has followed the product from the farmer planting the seed, to the facility extracting the oil, to the company bottling and labeling it. With the batch number, you can access GC/MS report and be sure that you are going to purchase a high-quality essential oil that contains the valuable chemical components that you are looking for.
All the other stuff you see on a label like: like 'Therapeutic Grade', '100% Pure', CPTG Grade… These are not certification categories. They are just marketing words that currently have no regulation. So, the most important point of this post is always to look for GC/MS report, check who is verifying the oils, and if there is no third party verification or GC/MS report is not available by request, just don’t buy this oil.
