All About Essential Oils

Essential oils are oil-based aromatic extracts derived from the leaves, stems, fruit, bark, flowers, roots, or seeds of plants. They are a highly concentrated form of volatile oils that have endless beneficial properties. Historians estimate that humans have been using essential oils for 5,000 to 6,000 years for medicinal, cosmetic, and hygienic purposes.

Types of Essential Oils

There are several ways essential oils are created. The ideal extraction process is determined by the oil’s source and how well its phytoconstituents respond to extraction. Distillation and using solvents are the most common ways of extracting essential oils. Plants or oils that are too delicate for distillation must be steam or Co2 expressed, mechanically crushed, or extracted using solvents. Others, like whole citrus fruits, may be mechanically rolled over needles that puncture and release essential oils, a process known as the ecuelle or scarification method.

Distillation

There are three distinct methods of distillation: water distillation, water and steam distillation, and steam distillation. Pure steam distillation is the gentlest extraction method. In water distillation, the plant material is boiled, and the essential oils are decanted off the water. Water-steam distillation involves both boiling and steaming the plant material.

Steam distillation takes place in a still. If the essential oils are processed fresh, this typically takes place in or near the same field from which the plant is harvested to preserve the delicate phytochemicals. The heat from the still forces the plant matter to release its oils at the lowest temperature possible to prevent burning or denaturing the more fragile phytochemicals. The steam carries the essential oils through the equipment to condense in another section of the still with the water. The essential oils are poured off the top of this (hydrosol) water.

Hydrosol, contains the water-soluble, aromatic phytoconstituents of the plant. Hydrosols are often used in cosmetics for their more subtle aroma and gentle, beneficial effects on the skin, but there is a whole therapy revolving around hydrosols that is just as beneficial and complex as essential oils. However, the qualities and benefits associated with each plant stay the same - so if you enjoy e/o you should also try hydrosols - flower essences - or bach flower remedies.

Enfleurage

Enfleurage is an old, tedious, and expensive method of collecting essential oils. Historically, essential oil producers used it for fragile plant sources, such as jasmine flowers, that couldn’t tolerate more aggressive extraction methods. The process involves gently placing flowers on top of a fatty medium, either a scent-free vegetable oil or lard, so that the volatile oils would transfer into the fat. These flowers were continually and regularly replaced on the surface of the medium until it was thoroughly imbued with the desired oils. Once completed, the producer would use alcohol to separate the essential oil from the fatty medium by allowing the alcohol to evaporate away. So yes, believe it or not - essential oils were much more expensive, once upon a time.

Solvent Extraction

A fairly new technology for extracting essential oils is called supercritical CO2 extraction. This method applies high barometric pressure under specific temperature conditions to release the oil from its source. Liquid CO2 is used as a solvent and poured over the plant matter to release the essential oils. Sometimes ethanol is added to this process. Afterward, the CO2 (or ethanol) evaporates and only the essential oil remains.

Alcohol tinctures are another method of extraction that uses ethanol to release essential oils. The plant matter is submerged in alcohol and the volatile oils of the plant are extracted by the ethanol. One potential downside of these tinctures is that they contain as much as 60-90% alcohol, and may not be an appropriate choice for everyone.


How to Select Essential Oils

The best quality essential oils are 100% pure, organically grown, and minimally processed. Many phytochemicals are sensitive to heat, light, and harsh chemical solvents, so they must be handled gently to retain the full spectrum of their beneficial constituents. If an essential oil provider doesn’t openly explain how they extract their oils, consider a different brand!!

Science has to catch up and set their skepticism aside when it comes to the concept of vibrations and energy signatures in healing. All living things resonate at a particular frequency that is affected by life experiences, environment, color, and any and all processes related to life. Vibration (vibe) is the speed at which molecules vibrate. This energetic signature is the essence of the plant that's medicinal/beneficial. By consuming or rubbing e/o on the skin, or even filling the air around you with e/o you are shifting the vibration or frequency of energy. Healing is all about resonance and atunement (atonement).


Essential Oils vs. Fragrance Oils

Most folk are introduced to essential oils (e/o) through scented candles and soaps. Unfortunately, most folk don't see that much of a difference between fragrance oils and essential oils - except one is cheaper and has a broader range of novelty scents - like Fresh Linen, Prairie Fields, Christmas Night, Tropical Retreat, and Caramel Cream Delight! ANY product laundry detergent, household cleaner, baby lotion, shampoo, face cream, sunscreen, makeup item, or perfume that lists FRAGRANCE in its ingredients - uses "fragrance oil" not e/o. Don't let the "all natural" prefix fool you!! 

More than 95 percent of the chemicals in synthetic fragrances are derived from petrochemicals. These chemicals include: benzene derivatives, aldehydes, phthalates, and a slew of other known toxins that are capable of causing cancer, birth defects, nervous-system disorders and allergies—some of which are cited on the EPA’s hazardous waste list. In the U.S., manufacturers can legally hide hundreds of synthetic chemicals in the one word—”fragrance”—without revealing what those "trade secret" ingredients are. This excuse to not label fragrance ingredients was initiated in an era when the major fragrance houses lobbied to protect their secret formulas made from flowers and oils. But those days are long gone. What the government is protecting now are manufacturers who have a license to poison the American public with more than 3,000 chemicals that are being absorbed, inhaled, and ingested daily.

Environmental Working Group (EWG) researchers found more than 75 percent of products listing the ingredient “fragrance” contained phthalates (THAL-ates) which have been shown to disrupt hormone activity, reduce sperm counts, and cause reproductive malformation, and have been linked to liver and breast cancer, diabetes, and obesity.  Additionally, studies by Dr. Philip J. Landrigan of the Mount Sinai Children’s Environmental Health Center, link fetal exposure with autism, ADHD, and neurological disorders.

AVOID ALL products with the ingredient “fragrance” on the label—including perfumes and colognes, baby lotions and wipes, air fresheners and candles, dryer sheets, detergents, and so on. Even if the front screams “fragrance free,” products can still contain fragrance ingredients as a masking agent to cover unpleasant chemical smells. Read the labels - and more importantly have the willpower to put it down and walk away!! What usually isn't mentioned is the HIGHLY addictive qualities of these ingredients. If you love yourself and your family - there's no other route to go, but cold turkey! Slowly build a collection of e/o, and use them where it counts most. Learn to appreciate the REAL smell of things again. Essential oil will not replace your Midnight Mochaccino - so deal with it!

Congress has banned some phthalates in toys, but as the recent study above suggests, others have been substituted in their place. Many countries have banned phthalates (EU, Canada, South Korea, Japan, even China). But the U.S. government demands such a high level of proof of harm that many agree it is simply impossible to reach—and our government is slow to respond, banning only a few chemicals in its history.

The greatest thing about essentials oils is that you're getting these incredible, (truly) natural scents that overflowing in healthful benefits. There's not one drop of guilt in any bottle, and you can use as much as you want (within reason and wallet allowing). You have the choice of using "fragrances" that at BEST will slowly make you and your family sick - or using e/o that heal from an energetic level all the way up through mental, emotional, and physical levels! Okay - really there is no choice!!


Common Uses of Essential Oils

Clean Surfaces, Air, and Clothes

Beyond just cleaning surfaces, the volatility of these oils makes them ideal for reducing microbial contaminants in the air. 

  • Use eucalyptus and tea tree oil to freshen humid rooms like the bathroom.
  • Add a few drops of lavender oil to a dry washcloth and throw it in the dryer with your wet clothes.
  • Use lemongrass or rosemary to freshen and disinfect the fridge or freezer by sprinkling a few drops on a damp washcloth and wiping down surfaces.
  • Freshen up your gym bag, locker, car, or shoes with a few drops on a cotton ball or piece of felt.

Get Rid of Shower Mildew

Shower mold is unsightly and unhealthy. To get rid of it, liberally sprinkle eucalyptus oil on any areas that have darkened, especially grout or the tracks of sliding shower doors. You can also apply to problem spots with a cotton swab.

Promote Skin Health

There are several skin care benefits that essential oils provide. Patchouli and clary sage slow skin aging and increase cell turnover to reveal fresh glowing skin. Orange oil revitalizes aging skin by promoting collagen production, just like the vitamin C in the whole orange.

Apply a drop of bergamot oil to soothe dry, cracked, or inflamed skin. Chamomile also helps moisturize dry skin to soothe itchiness. For dandruff, add a few drops of tea tree oil to your shampoo bottle and shake well to distribute evenly.

Patchouli also calms irritated skin and expedites wound repair. Slow or stop a small cut from bleeding with a small dab of cypress oil.

Moisturize Hands and Nails

For a DIY cuticle oil, dilute lemon or rosemary oil into sweet almond oil and rub into bare nails.

Clear Blemishes

Basil, bergamot, and cedarwood will help clear blemishes. A compress made with bergamot oil promotes the healing process by soothing swollen, painful skin eruptions. Cedarwood and orange oil help balance the production of skin oils.

Encourage Supple Lips

Topical bergamot oil minimizes pain from lip conditions, while lemongrass and peppermint promote clear, moisturized lips.

Calm Anxiety and Promote Relaxation

Essential oils are well known for their ability to improve mood. Lavender reduces feelings of anxiety that it’s encapsulated and taken orally by some people. Diffuse oregano, basil, black pepper, and cedarwood in a humidifier to create a calming home or work environment.

Discourage Harmful Organisms

Several essential oils are good for addressing topical Candida overgrowth, so you’ll have no trouble finding one that suits your preference. These include lavender, peppermint, sage, tea tree oil, thyme, tulsi, and clary sage. Make sure to apply them correctly. If your preferred essential oil requires a carrier oil, mix into lotion or coconut oil to apply.

For athlete’s foot, rub a few drops of cedarwood into your skin, or mix a couple of drops of tea tree oil into a teaspoon of a carrier oil and massage into skin. For nail fungus, use a cotton swab to apply 100% tea tree oil to the affected area.

Create a Rejuvenating Bath Elixir

Add a few drops of lavender, lemon balm, jasmine, or chamomile to your next hour-long soak. Drop the oil on your bath salts, on your bath bomb, or add it directly to the water. Boost the efficacy of your foot bath by resting tired feet and killing fungi. If you’re prone to urinary tract discomfort, using bergamot oil in the bath helps keep your bladder and kidneys healthy.

Assist Recovery After a Workout

Add a few drops of lavender, rosemary, or rose oil to a damp hand towel and freeze it. Fold over your eyes during savasana at yoga or drape it around your neck after your workout to cool down and boost your mood.

Increase Alertness

Mix a few drops of eucalyptus and peppermint oil together in your humidifier to increase alertness. You can also try basil oil, bergamot, and black pepper for similar results.

Boost Memory and Concentration

Inhale the vapors of black pepper, cypress oil, or eucalyptus to boost your concentration. Clary sage, cloves, sage, and coriander increase your ability to concentrate with the bonus of increasing your recall.

Deepen Meditation

To deepen your meditation practice, inhale the vapors of benzoin and cypress oil. It can help increase your focus and turn your thoughts inward.

Repel Insects

Peppermint, lemongrass, basil, and eucalyptus are natural insect deterrents. Either diffuse the oils to deter mosquitos, or use a mixture of the essential oil in vegetable glycerin and water and spray lightly on clothing. Just make sure to shake well first.

Support Normal Digestion

There are many ways that essential oils can help relieve gastric upset like bloating and gas. Lemongrass relieves gas and helps your body recover from stomach distress. For indigestion, dab a dry mint with peppermint oil. After letting it soak in thoroughly, quickly crunch the mint and swallow. For heartburn, use the same method but with chamomile oil. To relieve gas, stimulate appetite or prevent constipation, try basil, black pepper, or coriander oil.

Boost Cleansing and Detoxification

To stimulate your body’s natural cleansing abilities, dilute 3 drops of fennel oil into a teaspoon of olive or flax oil and swallow.

Calm Upset Stomach

Peppermint has long been used to quell nausea, and it’s an effective non-pharmaceutical option for people undergoing aggressive medical therapies, but there’s no scientific evidence it helps with morning sickness. You can also try inhaling the scent of ginger, peppermint, or coriander.

Appetite Suppressant

Inhale fennel or bitter orange to suppress appetite.

Encourage a Happy Mood

Surround yourself with uplifting scents when you’re feeling down in the dumps. Chamomile and clary sage resist down moods, basil oil brings about feelings of joy, and eucalyptus increases optimism.

Boost the Immune System

Many essential oils stimulate the immune system. Add them to your diffuser to reap the health benefits.

Promote Respiratory Comfort

Calm a cough with cedarwood and clary sage. If you already have a sore throat, soothe it with bergamot, lavender, or black cumin seed oil. If your lungs ache from coughing, inhale the scent of benzoin to soothe the discomfort. To reduce feelings of bronchial tightness, add 10 drops of clary sage to your humidifier. For a runny nose, inhale cypress or eucalyptus oil through your nose to dry it up.

Support Easy Breathing

Many OTC medicines contain chemicals that help loosen thick phlegm (so you expel it) but there are several natural ways to break through chest congestion. Use your humidifier to moisten dry air and diffuse the vapors of essential oils like benzoin, cedarwood, Manila elemi and eucalyptus to loosen phlegm and make your coughs more productive.

Clear Nasal Passages

To clear a stuffy nose, inhale the scent of basil or black pepper oil.

Return some luster to your locks with basil or chamomile oil. Evenly distribute 2-3 drops into dry hands and comb your hair with your fingers to coat strands lightly.

Scent-ual...

You can use essential oils to scent your home, car, or even yourself. Dilute a little rose, orange, lavender, and lemon oil in jojoba and rub into your pressure points for a perfume. To fresh your breath, add a drop of peppermint oil to your toothbrush and brush as normal after using toothpaste. For your home, use a humidifier to distribute the oil’s aroma throughout your house.

Be careful about putting essential oils in your car. Some oils contain plant compounds that, while natural, may be rough on finishes. You can easily apply a few drops to a cotton ball, piece of cardboard, or felt and put it somewhere in your car to keep it smelling fresh and clean.


Essential Safety Tips for Using Essential Oils

The dose is what matters most when using essential oils at home. Always check the label or consult your trusted essential oil producer’s website to ensure you’re correctly using these powerful oils. Many essential oils must be diluted to prevent skin irritation, and some should only be used in humidifiers or diffusers (especially with infants and small children).

Follow the directions when using essential oils. In addition to skin irritation, some essential oils increase your susceptibility to sunburn when applied to the skin. If you’re pregnant, nursing, or trying to get pregnant, consult with your healthcare practitioner before using any essential oils, even if you’ve used them before. Some essential oils stimulate the shedding of the uterine lining and should be completely avoided. If you cannot find information on the essential oil you want to use, do not apply to your skin or ingest it.

Some essential oil producers intentionally dilute their oils to make them safer for consumer use or to lower the price of extremely expensive oils like neroli. Make sure to buy your essential oils from organic sources and check to see that they are therapeutic grade if you intend to use them pure.
