Essential oils are present in plant tissues and comprise either fully formed terpenes or chemicals that are present in the metabolic pathway towards their formation. Essential oils often give the plant its characteristic odour. For example, the recognisable smell and taste of the mint group of plants is due to their essential oil. Common spices used in cruising such as thyme, oregano and sage are also recognisable due to their essential oils. Essential oils are used in aromatherapy where the oil can enter the body via inhalation or through the skin during massage. Consuming the spices and herbs containing the essential oils shifts the route of entry to body tissues to the gastrointestinal tract. Inhalation has been shown to activate olfactory senses and this may activate the central nervous system. In contrast, essential oils in the gastrointestinal tract may activate GABA receptors and thus confer slightly different effects. The route of entry for essential oils is therefore a consideration in their therapeutic effects.
