Aromatherapy involves the use of plant substances, known as essential oils that are extracted from aromatic plants.  Aromatic plants contain significant amounts of ‘volatile oil’ which gives each of them their distinctive fragrance.  They occur widely in the plant kingdom, not only in the flower, leaves and fruit but also in the roots, stems and in other parts of the plant.  Each plant essence is extracted from a single botanical source through a number of possible methods, the most common being steam distillation and cold expression. The more oil glands or ducts present in the plant, the higher the yield thus the less expensive the cost of the oil.  Essential oils can be found in specialised secretary structures, either on the surface of the plant or within the plant tissue. Many factors can affect the quality of the essential oil for example, soil type, climate and use of fertilisers and other chemicals, harvesting times, type and age of the leaf.  Most essential oils and aromatic extracts are destined for the flavour and fragrance industry, aromatherapy is only a tiny part of the vast industry.

Each essential oil has unique therapeutic properties that can be used into stimulate physical processes such as elimination, circulation, digestion or to ease muscular tension, aches, pains, etc. Today the essential oil industry is huge, and a wide body of knowledge concerning the physical, chemical and biological nature of essential oils has been accumulated.  However, modern uses of aromatic plants remain very similar to those of older cultures.
