Essential oils are natural aromatic compounds found in the seeds, bark, stems, roots, flowers, and other parts of plants. They can be both beautifully and powerfully fragrant. If you have ever enjoyed the gift of a rose, a walk by a field of lavender, or the smell of freshly cut mint, you have experienced the aromatic qualities of essential oils. In addition to giving plants their distinctive smells, essential oils provide plants with protection against predators and disease and play a role in plant pollination.
Essential oils are non water-based phytochemicals made up of volatile organic compounds. Although they are fat soluble, they do not include fatty lipids or acids found in vegetable and animal oils. Essential oils are very clean, almost crisp, to the touch and are immediately absorbed by the skin. Pure, unadulterated essential oils are translucent and range in color from crystal clear to deep blue.
Try this at home: Squeeze the peel of a ripe orange. The fragrant residue on your hand is full of essential oils.
In addition to their intrinsic benefits to plants and being beautifully fragrant to people, essential oils have been used throughout history in many cultures for their medicinal and therapeutic benefits. Modern scientific study and trends towards more holistic approaches to wellness are driving a revival and new discovery of essential oil health applications.
