The Physiology and Psychology of Aromatherapy

In aromatherapy there are two ways that essential oils can enter the body to work therapeutically: inhalation and absorption into the bloodstream.

Essential oils have three distinct modes of action:

  • They initiate chemical changes in the body when the essential oil enters the bloodstream by reacting with hormones and enzymes.
  • They have a physiological effect on the systems of the body.
  • They have a psychological effect when the aroma of the oil is inhaled.

The Science and Physiology of Smell – Olfaction

The term olfaction derives from the past participle of the Latin word, olfacere, which means “to smell”.

Our senses are heightened by the presence of smell. The scent of a flower may bring pleasure, or the smell of debris or noxious gases may warn about danger. It is our sense of smell that can affect our behaviour, desires and sometimes illness. Early cultures used aromatherapy in both spiritual and medicinal ways to ‘cure’ both physical and mental diseases. Throughout history, fragrances have been used to stimulate the unconscious mind by Greek philosophers and practitioners to transform a person’s emotional state. Essential oils and aromatherapy may be used to invoke feelings of positivity and wellness based on their individual properties.

Scents we find pleasurable (such as lavender or rose) may have a positive effect on our psychological wellbeing through:

  • Increased memory and cognition
  • Higher self-esteem
  • Mood improvement
  • Heightened emotions
  • Reduced stress

The term ‘Psycho-Aromatherapy’ was first mentioned by two Italian doctors, Giovanni Gatti and Renato Cajola. In 1923 they published L'Azione terapeutica degli olii essenziali, or The Action of Essences on the Nervous System. This paper outlined how certain scents can influence mood and emotions, and particularly how they can affect the depressed and anxious state.

In recent times, interest in the impact of certain odours has increased due to the documented positive effects on the physiological and psychological states of being.
