there are two ways that essential oils can enter the body to work
therapeutically: inhalation and absorption into the blood stream.
Essential oils have three distinct modes of action:
1) They initiate chemical changes in the body when the essential oil enters the bloodstream by reacting with hormones and enzymes
2) They have a physiological effect on the systems of the body
3) They have a psychological effect when the odour of the oil is inhaled
The science and physiology of smell – Olfaction
The term olfaction derives from the past participle of the Latin olfacere, which means “to smell”.
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 behavior,
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 involve feelings of positivity and wellness based on their individual
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
term ‘Psycho-Aromatherpy’ 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.
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.
Mechanism of Action
our olfactory senses to work we must first be capable of allowing
gaseous molecules of scent to pass through our olfactory system.
Olfaction occurs when specific molecules bind to receptors in our
bodies. Humans have several million olfactory receptors in the nasal
nasal passage is covered with a mucus membrane called nasal mucosa.
This mucosa consists of small nerve cells. These connect to the the
olfactory cilia, which look like tiny hairs. Olfactory cilia work by
detecting sensory stimuli which has been dissolved in the nasal mucosa.
The cilia then send the signals through the nerves back up to the brain.
This information goes straight to the olfactory bulb, which is at the
forefront of the brain, just behind the nose.
bulb is responsible for mapping the smells to determine what senses we
are experiencing. Once the signals are mapped, the information is then
sent to the higher levels of the brain such as the thalamus and the
hypothalamus for further processing and identification.
