Let’s start with the basics.

What Are Essential Oils?

Essential oils are highly concentrated liquids extracted from aromatic plants like grasses, flowers, trees, shrubs, roots, bushes, and seeds. The term “essential” refers to the fact that these oils contain the “essence” or distinctive scent and flavor of the plant.

Although sometimes called “volatile aromatic oils,” essential oils are different from the vegetable, nut, and fatty oils used for cooking and baking.

The amount of plant matter required to produce essential oils varies greatly depending on the species. For example, it takes approximately:

  • 220 lbs of lavender flowers to make 1 lb of lavender essential oil
  • 4,000 lbs of rose petals for 1 lb of rose essential oil
  • 1,500 lemons to make 1 lb of lemon essential oil

So essential oils are highly concentrated and contain beneficial plant compounds. But how are essential oils obtained from plants?

How Are Essential Oils Made?

There are two main methods of extracting essential oils from plants:

Distillation

Distillation is the most common method for producing high-quality essential oils. It involves heating plant materials in a still and condensing the evaporated compounds to collect the essential oil.

Water distillation – Plant material is suspended above boiling water. The steam extracts the oils.

Steam distillation – Pressurized steam is circulated through the plant material to extract oils.

Dry distillation – Plant material is heated without water to extract essential oil. Used for woods and barks.

The distilled essential oils are then separated from the water and purified using decantation and filtration.

Expression

Expression, also called cold pressing, is used mainly for citrus essential oils. Machines apply pressure to the rinds of citrus fruits like oranges, lemons, and grapefruits to rupture the oil glands and collect the oils.

The oils are filtered, allowing separation from the fruit juice. No heat is involved in this method.

Some companies may use chemical solvents in the extraction process or dilute essential oils with synthetics. Always look for 100% pure, organic essential oils.

Now that we know how they’re made, let’s discuss how these potent plant extracts actually work in the body.

How Do Essential Oils Work?

Essential oils can provide therapeutic benefits in several ways:

Topical Application

Applied to the skin, some plant compounds are absorbed into the bloodstream. Using a carrier oil helps dilution and absorption. Oils should always be diluted before applying topically.

Skin absorption – Some molecules penetrate the skin barrier and enter the bloodstream. Compounds with smaller molecules, such as menthol, are absorbed more readily.

Hair follicle absorption – Compounds penetrate open hair follicles and sebaceous glands on the scalp.

Intercellular absorption – Compounds move between skin cells, diffusing into the bloodstream.

Inhalation

Inhaling essential oils allows aroma compounds to travel directly from the olfactory nerves to the brain, especially the limbic system.

Olfactory system – Nerve receptors detect and process aromas, signaling the limbic system.

Limbic system – The emotions, memories, and hormones are affected by smell. This gives oils psychological benefits.

Respiratory absorption – Compounds enter the lungs and diffuse into the bloodstream for physical effects.

Ingestion

While some essential oils can be ingested in very small amounts, this application is controversial and should be done with care under the guidance of a professional.

Digestive absorption – Compounds may be absorbed via the digestive tract for systemic effects. Proper dosage is critical.

Mucosal absorption – Compounds enter the bloodstream directly from oral/intestinal mucosa without first-pass liver metabolism.

Let’s now explore some of the most popular essential oils and their common uses and benefits.

Most Popular Essential Oils

There are over 90 types of essential oils available. The most popular oils include:

Lavender – Relieves stress/anxiety, heals cuts/burns, improves sleep

There are many more excellent essential oils with an array of uses and benefits. We’ll cover some of these in more detail soon when discussing oil recipes and blends.

First, let’s look at some of the science and evidence behind the health benefits of essential oils.

Evidence for Health Benefits of Essential Oils

Essential oils have been used for centuries in natural medicine traditions for their therapeutic properties. And modern research seems to support many of these traditional uses.

However, high-quality scientific evidence on essential oils is still emerging. Many studies show promising results, but more research is still needed, especially high-quality clinical trials.

Here is some of the current evidence related to the top benefits of essential oils:

Stress Relief

Pain Relief

  • Peppermint and eucalyptus oils applied topically provide clinically significant pain relief by activating analgesics in the skin.
  • Clary sage, marjoram, thyme, and chamomile can reduce headaches by relaxing tense muscles, based on human trials.
  • Massage with diluted rosemary, lavender, and ginger oils significantly reduces knee pain from osteoarthritis.

Improved Sleep

Immune Support

Hair Growth

Digestive Aid

The research landscape on essential oils is expanding, with new studies emerging frequently. But current evidence suggests essential oils can be effective complementary treatments for various conditions when used safely and correctly.

Next, let’s look at some tips for safe usage.

Safe Usage of Essential Oils

When used properly, most essential oils are considered safe. However, there are some important safety precautions to keep in mind.

Always Dilute for Topical Use

Essential oils are highly concentrated and can irritate skin if applied undiluted. Always mix oils with a carrier oil before applying to skin.

Dilution guidelines:

  • For adults: 5-10 drops of essential oil per 1 ounce of carrier oil
  • For children: 1-3 drops of essential oil per 1 ounce of carrier oil

Carrier oils help spread essential oils and prevent sensitivities. Good choices are olive, coconut, jojoba, or almond oil.

Perform a Patch Test

Before applying any essential oil to skin, do a patch test to check for allergic reactions or sensitivities.

Apply 1 diluted drop to a small area of skin and wait 24 hours to see if any redness or irritation occurs before broader use.

Avoid Phototoxic Oils Before Sun Exposure

Some oils like lemon, lime, grapefruit, and bergamot contain compounds that react with UV light. This can cause burns or pigmentation changes.

Avoid direct sun exposure for 6-12 hours after applying these phototoxic oils to skin.

Use Proper Inhalation

Inhale essential oils directly from the hands, a tissue, or diffuser – do not directly inhale from the undiluted bottle.

Limit inhalation sessions to 30 minutes or less with proper ventilation.

Exercise Caution Around Children and Pets

Always research an oil for safety before diffusing or using topically around children or pets. Some oils like eucalyptus can be harmful if ingested.

Use kid-safe oils like lavender diluted properly. Avoid applying oils near faces of children.

Consult Your Physician If Pregnant, Nursing, or On Medications

Pregnant or nursing women should seek guidance from their doctor before using essential oils internally or topically.

Essential oils can interact with prescription medications or medical conditions. Check with your physician before using oils if on medications or being treated for a disorder.

Proper usage and handling is key to safely unlocking the benefits of essential oils. Now let’s look at what makes a high quality oil.

How to Choose High Quality Essential Oils

Not all essential oils are created equal when it comes to purity, quality, and efficacy. Here are some tips for choosing the best essential oils:

  • Therapeutic grade – Seek out oils specifically labeled as “therapeutic grade.” This means they do not have synthetics or impurities.
  • Organic – Oils certified organic by the USDA have higher standards and lack pesticide residues.
  • Reputable brand – Research brands and choose those known for strict quality control and testing. These oils tend to be more pure.
  • Native species – Oils should use plant species native to their country of origin for potency. For example, German chamomile, not Roman chamomile.
  • Unopened bottle – Ensure oils are sealed properly in dark glass bottles to avoid oxidation and UV damage.
  • No additives – Read labels closely and avoid oils with additives, diluents, or fragrances added. Seek out 100% pure essential oils.
  • Recent production – Check for harvest dates and buy as fresh as possible. Citrus oils have a shorter shelf life.

Investing in pure, high-grade therapeutic essential oils is key to experiencing their maximum benefits.
