Myrtle was used by the ancient Greek Dioscorides and has a lot of associations with love! Most notably it was associated with Aphrodite, the Greek goddess of love, and legend tells that Aphrodite hid her nakedness behind a myrtle bush! Greek brides today often carry myrtle in their bridal bouquets and even Queen Victoria of England mixed myrtle in her 1840 bridal bouquet, together with snowdrops. However, for its therapeutic properties, myrtle essential oil is most used for its antiseptic power – to learn more read my latest essential oil profile – myrtle essential oil…
Is there something you are curious about? Do you want to know more about a particular essential oil? Or carrier oil? Do you want to learn more about aromatherapy in the UK? Or in the USA? Is there a new aromatherapy practice or treatment you’ve heard about and want to share?
I would love to hear anyone’s suggestions or comments on any of aromatherapy notes blog posts or what you would like to see more (or less!) of! In addition to writing aromatherapy notes, I also maintain the Sedona Aromatherapie website library, Sedona Aromatherapie’s facebook fan page and am in the process of (in the next year) adding more sister aromatherapy websites (products and articles) to the Sedona Aromatherapie family! I regularly contribute to the aromatherapy section at suite101, an online media magazine and I also tweet about Sedona Aromatherapie and other aromatherapy articles on twitter too!
Look forward to your thoughts and comments!
As discussed in the post The Extraction of Essential Oils by Distillation and Expression, there are now new methods of extracting some essential oils. Both hydro-diffusion and carbon dioxide extraction are new methods, and there are some essential essential oils for sale which will be described as, for example, ‘CO 2 extracted’. Although distillation of essential oils remains the most popular and most frequently used method of extracting essential oils, it is worth mentioning the two newer methods of hydro-diffusion and carbon dioxide.
- Hydro-Diffusion Extraction (also known as percolation) – is the newer of these two extraction methods for essential oils. It is quicker than distilling an essential oil and works much like the process of a coffee percolator (hence its alternative name of percolation). As it is a fairly new procedure for extracting essential oils, it is not known yet whether essential oils obtained through hydro-diffusion extraction is of the same quality as those obtained through distillation. Additionally, not all essential oils, are suitable for hydro-diffusion.
- Carbon Dioxide Extraction – as the name suggests, carbon dioxide extraction uses carbon dioxide to extract essential oils. It is an expensive method of extracting essential oils, using both high pressure and low temperature to extract the essential oil from the plant material. It is said that carbon dioxide extraction produces an essential oil which is closer to the essential oil present in the plant (remember that the ‘essential oil’ obtained through distillation is not the same as the essential oil present in the plant; chemical components are ‘altered’ through the extraction process). Carbon dioxide extraction does not leave a trace of carbon dioxide in the resulting essential oil and essential oil suppliers are marketing these essential oils as ‘pure’; however, the essential oils obtained through carbon dioxide extraction are usually more expensive.
Personally, I have traditionally used distilled or expressed essential oils for pure aromatherapy use – until now. If research continues into the newer methods of hydro-diffusion and carbon dioxide extraction and I am convinced these essential oils are also pure, and can be bought at a reasonable price, I may consider using them in the future…
