Understand applications for aromatherapy that are used to Improve Wellbeing.

Aromatherapy is the use of scent – or aroma – for therapeutic purposes. (Although it is sometimes referred to as the use of fragrance, fragrance has a specific meaning tied to concentration of active ingredient.)

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. 

Lesson Structure

  • Identify the different properties of essential oils and describe their effects on the body.
  • Identify the various methods used in extracting essential oils.
  • Describe how essential oils can enter the bloodstream and the process of olfaction.
  • Learn some of the more common application methods used with essential oils in aromatherapy.
  • Ensure that essential oils are used in a safe and controlled manner and identify situations where aromatherapy might not be appropriate.
  • Develop an aromatherapy treatment plan for a client.
  • Identify which essential oils would be appropriate for use of various conditions relating to specific body systems.
  • Understand the scope and nature of an aromatherapy business.

Essential oils derived from plants consist of unique and complex chemical constituents that react with the body’s own chemistry to promote a variety of responses in specific organs and body systems.  In short: essential oils are a complex mixture of different naturally occurring chemicals extracted from plants.

Physiological effects caused by essential oils occur due to the absorption of molecules into the blood stream via external application, or via inhalation. Essential oils in a carrier oil applied to the skin are absorbed into the body either through hair follicles and sweat glands, or through the stratum corneum (the layer at the surface of the skin). When essential oils are inhaled, molecules will pass through the respiratory system to the alveoli in the lungs, where they will move into the bloodstream. Inhaled molecules can also reach the central nervous system via the nasal mucosa. 

When you examine cosmetic products, toiletries and even mainstream medicines sold by pharmacists, you may find that many of their constituents are essential oils derived from herbs. Any one plant can contain hundreds of different chemicals, including a combination of different essential oils, e.g. many lavenders contain lavender oil, but some cultivars can also contain camphor oil. The smell of lavender oil may be beneficial, but the smell of camphor oil may have a negative effect on the body. Separating these oils during extraction can be challenging unless you are using a cultivar with little or no camphor oil. In short: the proper processing of herbs for aromatherapy purposes can be complex, and success is dependent on several factors.

Note: Medical aromatherapy prescribes oral dosages of essential oils, however this method is not recommended and should only be used by medical aromatherapists (unqualified practitioners can cause serious harm). Training to be a competent medical aromatherapist takes years of study and experience.

This course may be a good starting point; but far more in depth study of chemistry, human biology and other health sciences is recommended before you would call yourself an aromatherapist.



  • Anyone wanting to develop a solid foundation for understanding aromatherapy.
  • People wishing to commercially produce aromatherapy products
  • Massage therapists or other heath industry professionals who wish to extend their knowledge of aromatherapy 
  • Retailers of aromatherapy products including candles, massage oils, etc.


We offer two different aromatherapy courses. The other one is broader based and contains more about growing aromatic plants for their aromatherapy uses; while this course focuses mostly on the human health benefits than this one.

There is a degree of overlap between the two; but if you are keen to learn as much as you can about aromatherapy; you may consider doing both.
