The History of Therapeutic Essential Oils
Although Ancient Egyptians are given credit for first using essential oils, the Chinese began using them around the same time period. Both the Egyptians and the Chinese used essential oils for medicinal purposes, especially to promote physical wellbeing. The Chinese pioneered expanding the use into other areas of alternative medicine, such as applying the oils topically during acupressure, or burning them while performing massage therapy practices. Essential oils were also used for nonmedicinal reasons, such as when they were burned as part of religious tribute rituals.
Essential Oil Extraction
When raw materials, either an entire plant or a select portion such as the leaves or roots, are introduced to a solvent, they begin to dissolve. This liquified version of the plant is what we call essential oils. There are many methods for carrying out this oil extraction process, but the most popular include steam distillation, solvent extraction, carbon dioxide extraction, maceration, enfleurage, cold press extraction, and water distillation. The method of extraction highly affects the quality of the essential oil produced. The best method of extraction varies from plant to plant because different levels of heat and pressure are used in different extraction processes.
For example, cold press extraction is far better than enfleurage when obtaining oils from citrus fruit peels. During an enfleurage extraction, the peels would be layered between natural fats to withdraw oil, but during cold-press extraction, the fruit peels are pierced and squeezed. This is not only more effective at extracting the oil, but it produces a much higher quality oil with stronger therapeutic benefits as well.
The Importance of Expertise
True essential oil experts know the importance of sourcing the best raw materials. It takes years of studying to acquire the skillset to properly access plants for potential therapeutic value. One of the first things all experts consider is the location from which the plant was grown. They also take note of the specific variety of plant, the fertility of the soil, altitude, and climate it was grown in, the cultivation process, and how it was handled and stored post-harvest.
Experts also consider any genetic differences in the plant, such as whether it was grown organically and whether it was extracted from a population or grown from a clone. Because the chemical composition of the natural material used for essential oils is so important, a wide range of factors may be considered. A principle of all plant and herbal medicine is to start with the highest quality ingredients.
A good example of how vastly essential oils can differ depending on the brand is lavender oil. Compare lavender oil from France with lavender oil from any other country, and you will notice an immediate difference. As soon as you open the bottle, you will smell a distinct difference in the aromas. You will also probably find the French oil to have higher therapeutic value as well. Even when comparing oils from the same country, there can still be variations in quality due to extraction methods and other previously mentioned factors.
How Essential Oil Affects the Body?
Essential oils are absorbed into the body quickly. When breathed in, the particles are carried through our airways and into the bloodstream. Within minutes your blood will fully circulate your body, carrying the essential oils to each and every molecule. Many essential oils are extremely potent, and inhaling them directly is not recommended as it can be overwhelming. Instead, the oils are released into the air, a practice known as aromatherapy. You can purchase products such as diffusers and aromatherapy lamps, or you can dilute the oils yourself with water in a spray bottle and spritz into the air.
Some essential oils can also be applied topically and absorbed through the skin. Just as some oils are too strong to inhale, most are also too strong to be applied directly and are instead mixed with a gentler oil before being applied. Essential oils are commonly rubbed on the body during therapies such as massage, reflexology, and acupuncture. A few drops of your favorite essential oils can also be added to bathwater or body lotions to absorb the benefits.
Key Essential Oils and their Benefits
There are more than 90 types of essential oils that can be utilized for their therapeutic properties. A few of the most popular types of oils include lavender, grapefruit, and cinnamon. Lavender is the most common and is known to have a calming and relaxing effect. It’s considered a nervous system restorative and is great for anyone suffering from insomnia, panic attacks, a nervous stomach, or a general sense of tension. Grapefruit is known to be stimulating to both the mind and body.
