What Are Essential Oils?
To understand essential oils, it’s best to get the basics on aromatherapy first.
Aromatherapy is simply the use of essential oils (or aromatic plant oils in a general sense) in a controlled a manner to improve physical and emotional well-being.
Aromatherapy has been in use as an alternative form of treatment for more than 2000 years, with its earliest application being traced back the year 100 A.D.
Today, aromatherapy is offered as an alternative medicine for many ailments, and as a complementary therapy alongside standard, medical treatments.
Aromatic plant oils (including essential oils, herbal distillates, absolutes etc.) are derived from a wide range of plants using various methods, and then applied to the body in different ways for healing and relief.
Currently, aromatherapy is taught and applied in spas, massage parlours and recreation centers for its many benefits, and its essential oils are now packed and sold individually for personal use.
Aromatherapy comes packed with benefits which, despite lacking medical evidence backing, still render it one of the best forms of medicine available.
It has been found to have healing powers over a number of ailments and conditions including anxiety, sleep disorders, stress, digestive disorders, depression, mood swings, poor cognitive performance, low energy levels and lots more.
Essential Oils: What Are They?
According to the International Organization for Standardization (ISO)’S Vocabulary for Natural Materials, an essential oil is a product made by distillation with either water/steam, by mechanical processing of citrus rinds or by dry distillation of natural materials.
Wikipedia describes an essential oil as a concentrated hydrophobic liquid containing volatile aroma compounds from plants. In simpler terms, essential oils are volatile liquids got from plants that have positive effects on the body.
Essential oils occur naturally in the roots, flowers, leaves, and stems of plants, which produce them for various purposes ranging from protection to pollination to allopathy.
When extracted, they possess even more positive abilities for the body. There are over 100 varieties of essential oils today, although only a few may be available for sale in drug stores and supermarkets.
How Essential Oils Are Produced
For an essential oil to be termed as a ‘true essential oil’, it must have been extracted from its plant source using physical methods.
The most popular physical methods include distillation (using steam, water or both), cold pressing (also known as an expression) and maceration.
Distillation is used for most essential oils, including peppermint, lavender and eucalyptus oil. The process involves placing raw plant material such as the leaves, stem or bark into a distillation flask above boiling water.
The steam from the boiling water is passed through the distillation flask to vaporize the volatile compounds in the plant material.
The resulting vapors are then passed through a coil into another flask where they condense to form a liquid called a herbal distillate.
Other essential oils may be extracted using solvent extraction, absolute oil extraction, resin tapping and other complex methods. Whatever the case, essential oil extraction is a long, winding process, which explains their high prices.
Benefits Of Essential Oils
Essential oils have a great assortment of benefits for both the body and the home, as shown below.
Inhibition Of Microbial Action
Essential oils such as oregano oil and thyme oil have been found to effectively inhibit the action of bacteria such as Escherichia coli and Bacillus cereus in the body.
Its active ingredient (a terpene called carvacrol) causes damage to the cell membranes of these cells, killing them before they can cause bodily harm.
The thymol from thyme oil possesses strong antibiotic properties when used alone, and has been found to reduce bacterial resistance to drugs such as penicillin.
Essential oils have long been prescribed as a natural remedy for headaches and migraines, thanks to their calming effect on the nervous system and their ability to improve circulation.
All you have to do is inhale the oil or apply it topically around the neck or on the sides of the head periodically. Peppermint and eucalyptus oil are some of the most recommended for this purpose.
Essential oils contain compounds that accelerate the healing process of the body after an illness or major surgery through their ability to improve circulation, their antibacterial properties, and general healing abilities.
Universal oils such as lavender oil are commonly used as complementary medicine for standard medicine because of this.
If you easily shift from happy to angry suddenly, what you need is a good inhalation of an essential oil such as frankincense oil, jasmine oil, tea tree oil or lavender oil to get you back on top.
These oils stimulate the limbic system of the brain after absorption, which is responsible for emotions and mood management.
Whether it’s insomnia, sleep apnea or just plain lack of sleep at 2 am, a good essential oil can fix you up in no time.
Lavender oil is a big favorite for this, but you can also use sandalwood oil or ylang ylang oil for calming and sleep inducing abilities.
You can spray the oil in the air, sniff it off a cotton ball or make a few drops on your pillow to spread the oil and inhale it easily.
Relieving Stress, Depression & Anxiety
Because of their calming and relaxant properties, many essential oils such as lemon oil, lavender oil, vetiver oil and ylang ylang oil are commonly used to relieve stress, improve spirits, tackle depression and calm anxiety.
Their popularity for this purpose is heightened by the fact that there are few or no side effects at all in comparison with some common medically prescribed drugs.
Whether it’s in the joints or the head, bodily pain is a nuisance. Essential oils such as wintergreen oil, tea tree oil, cypress oil, basil oil and birch oil relieve bodily pain by calming inflammation, relieving sore muscles, supporting muscle growth and more.
Boosting Cell Development And Function
Essential oils such as cassia oil, arborvitae oil, and frankincense oil have been found to greatly trigger better cell development and facilitate faster cell renewal in the body.
These abilities directly affect the healing of wounds, growth of hair, skin and nails and other bodily activities.
Healing Wounds, Burns And Cuts
The antibacterial, antifungal and antiseptic properties of many essential oils make them ideal for treating open wounds such as burns and cuts to total healing.
Oils such as oregano oil, eucalyptus, and tea tree oil are particularly preferred for their drying and healing effect on wounds.
Increasing Energy Levels
Essential oils from plants such as cardamom, clove, rosemary and black pepper give you twice as much energy as what popular energy drinks give you in one take.
You also get less of the side effects, which is an added advantage. That explains why they are popular for boosting low energy levels in tired people today.
Skin And Hair Growth
If you make your research, you’ll find that some essential oils are already stapled ingredients in skin and hair products.
That goes to show their ability to improve hair growth, stop hair loss, smoothen skin by triggering faster cell renewal and heal scars among other abilities.
For this purpose, essential oils from eucalyptus, frankincense, geranium, bergamot, sandalwood, coriander, jasmine, lavender, lemongrass, tea tree, patchouli, rose and ylang ylang are highly recommended.
Relieving Digestion Related Ailments
Improving and easing digestion is one benefit that most essential oils share for the body. Essential oils such as peppermint oil, oregano oil, rosemary oil, spearmint oil, lemongrass oil and sweet fennel oil help relieve digestive ailments such as constipation, bloating and indigestion.
Other benefits of essential oil
Improving cognitive abilities
For treating varicose veins and cellulite
Relieving bug bites
Relieving sore feet
Relieve sun burn
Healing morning sickness and nausea
Air cleaning and purification
Cleaning burnt pans
Scrubbing sinks, clothes etc.

How To Apply Essential Oils
Essential oils can be applied topically, aromatically or by ingestion, depending on the desired effect, the type of essential oil to be used, and the purpose of use. They can be applied as ‘single oil’ or blended with each other for a better effect.
Stemming from the word ‘aroma’, this form of application involves inhaling the essential oil. The aromatic application is highly popular for its effectiveness over a number of ailments.
After inhalation, essential oils are easily absorbed by the nose’s smell receptors, which are directly linked to the limbic system of the brain.
To convert the oil to gas/fumes, the essential oil is placed in a tool called a diffuser and heated to evaporation. The fumes that escape into the atmosphere are then inhaled.
The essential oil can also be inhaled by holding your head over a basin of hot water into which drops of essential oil have been added. The hot water vaporizes the oil, allowing you to inhale it by breathing in deeply.
Topical application involves the actual application of an essential oil to the skin for relief. The method is backed by the fact that essential oils are easily absorbed into the skin because of their lipid solubility.
And because essential oils are highly concentrated in nature, they have to be diluted with a carrier oil first before topical application.
What are carrier oils?
Carrier oils are solutions used to dilute essential oils and render them comfortable for topical application. Common examples of carrier oils include jojoba oil, avocado oil, kernel oil and more.
Typically, drops of essential oil are mixed with a carrier oil before application to the body. The idea is to reduce their concentration and prevent irritation, allergies, photosensitivity, burning and other dangerous side effects.
Topical application can also be achieved with the help of a few techniques.
Gargling – Here, you add a few drops of essential oil in warm water and then gargle the mixture on your throat for a few minutes.
Spit it out after and don’t swallow either. Mouth and throat infections are some of the ailments usually treated with this method.
Applying a compress – Add a few drops of essential oil to a carrier such a water or jojoba oil and stir for proper mixing. Dip a thick cloth into the mixture and applied it on the skin for some time. You can use this method for all your stiff and inflamed joints.
Massages – You can add a few drops of essential oil to a natural carrier oil and then rub the mixture gently into the skin with a massage. Massages are highly recommended for stress relief.
Bath – Rather than use plain bath water, add some drops of essential oil in it for increased health benefits. Essential oils do not dissolve in water, which is why they’ll remain on the water surface unless you add a dispersant to the water such as Epsom salts.
Using the water while the essential oil still lies on the surface is dangerous, and may result in skin allergies, severe irritation and other side effects.
The discussion about whether or not essential oils should be ingested is always a heated one. While some aromatherapists recommend eating essential oils to treat internal ailments, others refute the idea, saying it’s dangerous and lacks medical evidence.
You can always use essential oils in controlled amounts as flavoring agents in beverages and foods to take advantage of their benefits. Just make sure the amount used is right for ingestion.
On many fronts still, the essential oil is not recommended for ingestion, except in severe cases. Even in such cases, constant supervision by a licensed aromatherapist is required.
The reasoning is that its concentration is quite dangerous for the internal organs and the good bacteria that live in the gut.
Safety When Using Essential Oils
Essential oils may have an endless list of benefits for the body, but they still need to be used with care to avoid danger and long lasting side effects such as headaches, allergies, rashes, and death.
Here a few safety tips to consider when using essential oils.
Always dilute essential oils with carrier oils before application to the skin to avoid burning, irritation and other side effects.
Children below 7 years of age should not be allowed to inhale essential oils from a basin. Children above 7 years should wear safety goggles during the procedure.
Always check the bottle or packaging to note the preparation and dilution guidelines before using an essential oil. If you can’t find them, contact a licensed aromatherapist or browse for instructions on the internet.
For younger children, essential oils are not necessary or recommended as part of a bath. Their skins are still sensitive and need to be handled with care.
Do not use bath water with essential oil without adding a dispersant such as Epsom salts first. Essential oils will not dissolve in the water without a dispersant, and that makes the water dangerous for use.
Avoid applying essential oils to sensitive areas of the body such as genitals, eyes, ears, and mouth. If you must apply, follow the dilution guidelines very closely to prevent burning of the sensitive skin.
Keep your essential oil out of reach of children and pets to avoid accidents and wastage.
Go for high-quality essential oil from trusted brands to avoid synthetic chemicals, flavorings, and fragrances that might trigger allergies and dangerous side effects.
Carry out patch testing for different oils before applying them to your body. A patch test involves applying a small mixture of essential oil and a carrier oil to your forearm to see its effects on your skin. If a particular oil causes an irritating sensation, consider diluting it further or substituting it.
Pregnant women and nursing mothers should steer clear of essential oils until they are okay again.
Protecting Your Essential Oils
It’s no secret; essential oils can be quite expensive. One spoon may cost well over $50 for the rare types, and that’s just the beginning.
The worst part? They also get spoilt easily. The same essential oil that could last 2 years can get spoilt within a week following exposure to oxygen. Imagine the loss.
What damages essential oils?
The main culprits are heat, light, oxygen, and moisture. Each of them alters the chemical composition and physical structure of the oil, lowering its healing powers.
Exposure to oxygen results in oxidation, which triggers evaporation of the oil and subsequently alters its chemical composition.
Essential oils are flammable (classified as Class 3 Flammable Liquids), and most have flashpoints (the temperature at which they explode) ranging between 50 and 60°C.
Heat and light increase the essential oil’s temperature, which might cause them to burn and break down. Light energy, especially sunlight, is known to change the color of oil over time.
Essential oils are also highly volatile, which means that they can easily change in state with the presence of new energy such as heat or light.
If you want your oil to stay viable for longer after you purchase it, you’ve got to protect it accordingly and store it safely.
How To Store Your Essential Oils
Don’t just place your essential oil bottles anywhere and expect the oil to keep making wonders in your life. Here are a few storage tips you should use.
- Keep your bottles in a cool, dark, dry place. A lidded wooden box you can easily carry is a good choice, and some come with space for over 60 bottles!
There is also the aromatherapy storage box, designed with this particular purpose in mind. If you can’t access either, consider using a drawer in one of your cupboards as long as it’s not exposed to sunlight.
- A refrigerator is recommended for some oils, especially carrier oils. You can always take the carrier oils out of the fridge 12 hours before actual use and warm them slightly with your hands.
- Avoid placing essential oil bottles on window sills and in areas next to open windows that let in sunlight.
- Keep your oil bottles away from sources of ignition such as stoves and fires.
- Use amber, green, blue or cobalt colored glass bottles for storing your essential oils rather than a clear glass one. The colored glasses keep out ultra violet rays from the sun better than clear glass ones.
- Never store your essential oils in plastic bottles; the oils will corrode the container and degrade it completely.
- Don’t allow space to increase in your essential oil bottles. Always transfer oil from large half empty bottles to smaller ones that will appear full after. The idea is to reduce the airspace in the bottle and limit chances of oxidation.
- Avoid using rubber stoppers; they are liable to melting away and mixing with the oil over time.
- When using the essential oil, close the bottle immediately after use to prevent oxygen from getting in.
- Always keep the reducer in the bottle as it helps with the sealing.
Are All Essential Oils Equal?
The grading of essential oils has been a major cause for discussion for many years. The fact still remains that essential oils are not equal in nature. On their packaging, essential oils may be branded as food grade or therapeutic grade.
Essential oils marked as ‘food grade’ are not effective for aromatherapy use, and are usually mixed with other synthetic chemicals first before sale.
Ideally, the right oil for your aromatherapy use should be labeled ‘therapeutic grade’ and have the Latin name of the plant displayed on its packaging.
Still, that is not a guarantee for high quality, as is a high price on the tag. The FDA does not regulate the aromatherapy industry, which means that you’ve got to do more research about a product to be sure of its quality.
We recommend that you do some background research on the company selling the essential oil and review its growing methods, harvesting methods, extraction formula and more first.
These are the factors that define a high-grade essential oil, in addition to the plant species, weather, season, location, and chemicals used on the plant.
There is a world of benefits for you to reap from essential oils and an equally diverse selection of oil types to choose from.
Despite lacking medical evidence to support most of their healing abilities, essential oils are still used today to improve health and well-being and the results are positive.
