What are essential oils?

Essential oils are highly volatile, fat-soluble, chemical mixtures that contain a huge number of chemical compounds. Each essential oil has its own character and therefore its own area of application. Essential oils are produced by the plant in oil glands. Depending on the type of plant, these are found in the leaves, flowers, seeds, fruit peels, roots, but also in resins, bark or wood. Essential oils are the scents and communication substances of a plant.
