Essential oils are concentrated in and extracted from different parts of herbs, roots, grasses, trees,
shrubs, fruits and flowers. Once extracted, the essential oil can be applied externally to the body using a
lotion or carrier oil; inhaled using diffusers, humidifiers and vaporizers; or ingested through food. They
can be used in the home for cleaning, hygiene, beauty, cooking, gardening, pet care, and pest control.
