Essential oils are oils in their purest form that have been extracted from the flowers, roots, leaves, stems, or bark of certain plant species. These essential oils are NOT the same type of essential oils that are found at your local craft store, grocery store, or flea market. These are the purest and finest aromatherapy grade essential oils available. Essential oils should be diluted with a carrier oil such as sweet almond oil before placing directly on the skin. Please do a patch test for skin sensitivity.
