AROMATHERAPY ONLINE COURSE

Develop a basic understanding of the safe use of Aromatherapy oils; and their production. This course is aimed at the introductory level of education in Aromatherapy. It is suitable for those wishing to gain knowledge of using Aromatherapy in the home or for those working in a related discipline. Knowing the botanical names of plants and how they are derived is an important part of Aromatherapy.

Most people know essential oils by their common names, such as Lavender, Thyme or Eucalyptus. For instance, there are several different types of plant that are commonly known as Lavender, and more than one of these plants are used to produce lavender oil. Oil distilled from True Lavender or Lavandula angustifolia, is the highest quality lavender oil. However, lavender can also be distilled from Lavandula x intermedia and Lavandula latifolia. All three smell very similar, and can even be confusing for an experienced aromatherapist, but the chemical composition of Lavandula angustifolia is far superior to the other two species and is a much better therapeutic oil.

There are 8 lessons as follows:

  1. Plant Classification - Understand the classification system used for naming plants and to be able to identify the family, genus and species names of plants used to produce essential oils. Define aromatherapy and its history, to understand how aromatherapy works, and the basic chemistry behind it.
  2. Introduction to Aromatherapy - To define aromatherapy and its history and to understand how aromatherapy works, and the basic chemistry behind it
  3. Essential Oils - Identify a range of essential oils and their uses

HOW CAN WE WORK WITH THE SENSE OF SMELL?

Scent or fragrance can impact the body in many ways; but often more subtle ways than other senses (sight, touch, taste).

The human nose contains a complex system of nerve channels that connect into olfactory centres in the brain.

When chemicals (eg. essential oils from plants) are inhaled they have an affect upon an olfactory centre in the brain, known as the limic system. The limic system is associated with a range of basic drives including hunger, thirst, sex and also (subtly) emotions, memory, creativity, innovation, etc.

The olfactory area also affects the hypothalamus which in turn influences the pituitary gland which controls production of body hormones.  In these and other ways, fragrances can have a very real impact upon both human psychology and human physiology.

Thousands of Different Fragrant Chemicals

Different types of fragrant chemicals can have different affects. Not all are used, nor do all have potential for use in aromatherapy; but many do.

Example:

Terpenoids are just one group of fragrant chemicals found in plants. They are a vast group of compounds with more than 30,000 identified. They make up more than half of all plant secondary metabolites. They are volatile, aromatic hydrocarbons and may be considered polymers of isoprene, which has the formula C5H8.  As such, all terpenes have repeating 5-carbon isoprene units.

The simplest terpene is one isoprene unit and is known as hemiterpene. Terpene proper is two isoprene units bonded together and is denoted by C10.  Sesquiterpene has three bonded isoprene units and is denoted by C15, diterpenes (C20) have two terpene units, and so forth. Terpenoids are modified terpenes e.g. by the addition of oxygen.

A sesquiterpene lactone called artemisinin, which is isolated from Artemisia annua (sweet wormwood), gives rise to arteether. This is used as an anti-malarial medication. A few other derivatives of artemisinin have also been trialled for potential anti-malarial qualities. Diterpenes include taxol and giberrellic acid which regulates plant growth. Triterpenoids which are modified triterpenes (C30) include saponins, steroids and cardiac glycosides. Saponins are sugars bound to triterpenes and are found in ginseng, primula root, liquorice and sarsaparilla root.
