If you have ever enjoyed the scent of a rose, you’ve experienced the aromatic qualities of essential oils. These naturally occurring, volatile aromatic compounds are found in the seeds, bark, stems, roots, flowers, and other parts of plants. Essential oils provide their native plants with protection against environmental threats and play a role in plant pollination. In addition to their intrinsic benefits to plants, they are beautifully fragrant to people and have a long history of being used in food preparation, beauty treatment, and holistic practices.
