There are many brands of essential oils to choose from. Unfortunately, what you see is not always what you get. Some brands promising 100 percent purity contained no essential oils at all. 
On the right, these oils are marketed as "100% Pure." They were found to have synthetic additives. Each 15ml bottle oil is sold for $2.97, regardless of the type of oil.

Essential oil fraud is a growing trend following trends in the food industries.

As consumers, we must gather information to make educated decisions not only protect our pocketbook but to also protect our health.
