The application of essential oils to suit individual needs. The oils work directly on the chemistry of the body, via the skin and bloodstream. Essential oils are extracts that contain the substances that give plants their smell. Tiny glands in the petals, leaves, stems, bark and wood of many plants and trees produce them. In nature, they are released slowly, but when heated or crushed, their oil glands burst, releasing the plant’s aroma more strongly. The therapist will take into account your emotional, physical and spiritual health and chose an oil that is appropriate to the presenting problem.
