Develop a basic understanding of the safe use of Aromatherapy oils; and their production. This aromatherapy 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 intermediaand 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.
