  • What are essential oils?

However, essential oils are not essential for human health (unlike essential minerals and vitamins). Adulteration of essential oils has been reported in the marketplace with less expensive or synthetic oils, but authentic lavender and tea tree essential oils can be identified by chemical analysis.
