What is a Pure Essential Oil?

While Canadians are familiar with synthetic fragrance oils, by and large, they have little or no knowledge about therapeutic health benefits of genuine, pure essential oils. Unlike North America, in Europe, high quality botanical plant derived essential oils are prescribed for internal use by medical doctors in hospitals.

In the last decade, essential oils have become a popular item, sold everywhere, which raises the question, "Do we really know what we are getting?"

What is a genuine, pure essential oil?
Essential oils are more than merely plant secretions. The evaporation of essences from a plant surface is a defence mechanism against infection by bacteria, fungi and pests. Aromatic plants have a protective aura of scent, just as all living things have an aura of light. This aromatic aura also protects plants from excesses of heat and cold. To qualify as an essential oil, it must be 100 percent natural, preferable harvested from certified organic plants or wild crafted, and free of herbicides, pesticides and chemical fertilizers.

A description of the biochemical compounds (using gas chromatography and mass spectrometry) will confirm if an oil is 100 percent authentic and contaminant-free. There are five different processes for making essential oils: - Steam distillation (this method produces the highest quality oil, but it must be slow and prolonged) - Solvent extraction - Expression - Maceration - Enfleurage

Assessing quality
To assess quality, the label and/or therapeutic fact sheet should have these items listed: - Complete Latin name, genus and species - The distilled part: it is vital to know which of the plant (flower, leaf, bark etc.) has been distilled. - The chemotype: recognized internationally, and widely used in scientific publications, chemotypes, are associated with the Latin scientific denomination, allows the perfect comprehension of the mode of action of an essential oil, so an oil can be used correctly. The type of soil, altitude, sunlight, climate, and surrounding plant population are all elements that influence the essence manufactured by the plant. All essential oils are not created equal.

The price reflects many factors, such as the number of kilos of plant materials needed to make an essential oil, which is why they are sold in bottles of 5, 10 or 15 millilitres only. Some oils are even sold by the drop. Why? One kilogram (approx. 1 litre) requires: 6 to 7 kg of clove flower buds, 50 kg of lavendin, 150 kg of true lavender, or 3,500 - 4,000 kg of Damask flower rose (1 hectare of roses)!
