Teachers in English grammar would certainly be annoyed with the phrase pure essential oils. For them, essential oils are naturally pure and incorporating the phrase “pure” to this is just to be verbose. However, it turns out that there are good reasons to ignore the teacher’s objections as there are several cases where essential oils are mixed with different other oils, or the client has actually been fooled with completely synthetically produced oil. Therefore, you need to take people seriously when they want to get pure essential oils.
Essential oils are complex mixtures of volatile compounds and isolated by physical means only (pressing and distillation) from whole plant or part of a plant. There are almost uncountable number of single substances and a tremendous variation in the composition of essential oils. Many of these volatile oils have diverse ecological (the scientific analysis and study of interactions among organisms and their environment) functions.
Essential oils can play a role in your life through many applications. Essential oils are the volatile, aromatic, non-water soluble liquids obtained by steam or water distillation of plant parts. Most essential oils are primarily composed of terpenes and their oxygenated derivatives. Different parts of the plants can be used to obtain essential oils, including the flowers, leaves, seeds, roots, stems, bark, wood, etc. An essential oil may contain up to several hundred chemical compounds and this complex mixture of compounds gives the oil its characteristic fragrance and flavor.
The chemistry of essential oils is influenced by the local geography and weather conditions, as well as the season and time of day when the plants are harvested, how they are processed, and how they are packaged and stored. Each plant is unique in its chemistry so essential oils are never exactly the same-this is different from pharmaceutical drugs that are synthetically reproduced to be identical every time.
Frankincense, an oily gum resin from the tree Boswellia sacra and related species, is named in the Bible as one the three gifts given to the baby Jesus by the ‘Three Wise Men’. It has been used for thousands of years in many different cultures. The name ‘frankincense’ is derived from the Old French ‘franc encens’, meaning pure incense or, more literally, free lighting.
