Aromatherapy Health Applications

Understand the health applications for using aromatherapy and essential oils on the human body. This course explains the properties of essential oils, how the oils affect the human body, using them safely and how to start your own business using your new skills in aromatherapy.
In aromatherapy 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”.

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 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 properties.

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

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

There are many ways to leverage the therapeutic power of scent, from using candles and incense through to washing with particular hair and body products. Oils are also used in a variety of ways, including massage, or as a complement to alternative health treatments. Understanding the principles of aromatherapy, and the benefits of the most common scents, can be useful in a variety of contexts within and without the health world.
