Essential oils as used in aromatherapy are an effective, side effect-free way to treat anxiety. Learn how to use them to reduce stress and depression too.
Essential oils may bring to mind scented candles and spa massages.
They may sound “new age” but in fact are ancient.
They’ve been used for over 6,000 years in Egypt, Greece, China, India and the Roman Empire and are frequently mentioned in the Bible.
They may also sound lightweight as serious remedies, but their use is recommend by such prestigious institutes as the Mayo Clinic and the National Cancer Institute. 
The US National Library of Medicine, a database of scientific research, lists over 15,000 studies that have been done on essential oils. 
They’ve become so mainstream, they are even being extolled in business magazines as a “secret weapon” for a healthy and happy workforce. 
If you are looking for a natural, side effect-free way to address anxiety, here’s why essentials oils are definitely worth considering.
How Essential Oils Affect the Brain
Aromatherapy is a healing technique that uses essential oils — concentrated fragrant extracts taken from the roots, leaves, seeds, or flowers of medicinal plants. 
Essential oils are extremely concentrated.
It takes a whopping 220 pounds of lavender flowers to make 1 pound of lavender essential oil. 
It’s not completely understood how essential oils work, but they seem to work by tapping into the powerful relationship between smell and the brain.
Scent receptors in the nose send chemical messages by way of the olfactory nerve to the limbic system, a primitive area of the brain that deals with basic emotions (like anger and fear) and memories. 
Olfactory signals from essential oils are thought to impact brain chemical production thereby affecting both mental and physical health. 
The Connection Between the Brain and the Sense of Smell
Here’s a real life example of how the surprisingly strong connection between smell, emotion, and memory works.
You’ve probably experienced “olfactory deja vu,” where a smell elicits a powerful memory and corresponding emotion.
The trigger can be any smell that’s associated with an emotionally charged memory — your dad’s aftershave, cookies in the oven, or the smell of pine trees.
For a moment you’re transported back in time.
You may be surprised at the clarity of your memory.
You may actually experience the same emotions you felt at that time.
This kind of deja vu is associated more strongly with your sense of smell than any of your other senses.
And it’s this connection between smell and your brain that may be the underlying reason aromatherapy works as a useful emotional healing tool.
The Best Essential Oils for Anxiety
Now that you have an idea of how they work, let’s take a look at which essential oils are the most effective for calming the anxious mind.
There are dozens of essential oils that are used for stress relief and anxiety.
If you are new to aromatherapy, I don’t want to overwhelm you!
So I’ve narrowed the list down to my three personal favorites for their proven effectiveness, safety, and versatility.
Versatile Lavender — the Most Popular Essential Oil
Lavender is the most studied and the most widely used essential oil. 
Lavender is so versatile I like to call it the “Swiss army knife” of essential oils — there are few things it isn’t good for!
It’s also one of the most gentle essential oils and is safe to apply to the skin directly. 
Lavender is widely appreciated for its ability to calm and relax and is often included in personal care items such as soap, lotions, shampoos, and massage oils.
A few drops on lavender oil on your wrist or on a cotton ball tucked into your pillow can help you sleep.
But lavender isn’t just about relaxing baths and massages.
It’s a serious and effective treatment for anxiety.
Research has found lavender to have anti-anxiety, antidepressant, mood stabilizing, sedative, and neuroprotective properties. 
Unlike most essential oils, lavender can be taken internally, provided you are using “food grade” oil.
One study found that when compared to prescription tranquilizers, oral lavender oil capsules worked just as well to relieve generalized anxiety disorder, but without the side effects and risk of addiction. 
If you try only one essential oil, make it lavender.
Uplifting Bergamot for Anxiety and Depression
Bergamot is a type of orange grown mainly in Italy.
The fruit is not considered edible but bergamot essential oil is extracted from its skin.
You may be familiar with bergamot as the unique ingredient in Earl Grey tea.
Bergamot essential oil has been proven as effective as Valium for anxiety
Most citrus-based essential oils are good for improving mood, but bergamot is a standout for depression. 
All citrus-based essential oils including bergamot can cause photosensitivity.
Unlike lavender, bergamot should not be applied to the skin in its undiluted form.
So if your skin is sensitive, to be on the safe side, don’t apply topically before spending time in the sun.

Calming Gentle Chamomile

You probably are familiar with chamomile as a relaxing herbal tea for insomnia and stress relief. (17)
But you may not be as familiar with chamomile as a relaxing essential oil.
There are many species of chamomile. (18)
The two most popular ones used as essential oils are:
  • German or wild chamomile (Matricaria recutita)
  • Roman or English chamomile (Chamaemelum nobile)
Both offer similar health benefits. (19)
Chamomile essential oil is so gentle it’s even safe to use with irritable babies (in a very diluted concentration).
Besides treating anxiety and insomnia, it’s commonly used for stress-related skin conditions like eczema.

Other Essential Oils for Anxiety, Stress, and Depression

Lavender, bergamot, and chamomile aren’t the only essential oils to consider for stress, anxiety, or depression.
If you’re looking for other choices or want to expand your repertoire, here are some other relaxing essential oils you can try: (2021)
Note that some serve a dual purpose and will be found on both the anxiety and the depression lists.

How to Use Essential Oils

Essential oils are usually sold in colored glass bottles in 1/2 ounce or 10 ml sizes.
Unlike herbal remedies for anxiety, essential oils are not generally taken internally.
Instead they are inhaled or applied to the skin.
And since only a few drops are needed those tiny bottles go a l-o-n-g way!
If you’ve got a bottle of essential oil, but aren’t sure what to do with it, here are some time-honored ways to get the most out of it.

How to Apply Essential Oils Topically

Since essential oils are extremely concentrated, they usually are not applied directly to the skin.
Instead they are diluted into what is known as a carrier oil.
Carrier oils are natural vegetable-based oils — definitely not mineral-based baby oil.
My favorites are almond oil, jojoba oil, and apricot kernel oil.
A few drops can be added to the carrier oil or lotion and rubbed into the skin.
You can add a few drops to a bath or into a tub to soak your feet.
There are aromatherapy balms, mists, and roll-ons that contain anti-anxiety ingredients that you can conveniently use on the go.
You can rub on your temples or wrist, or dab under your nose whenever you need a little extra stress relief.

How to Inhale Essential Oils

Another way to get the benefits of essential oils is to disperse them into the air.
You can add 1-2 drops into a pan of hot water and breathe in.
You can put a few drops in a spray bottle with water and spray into the air.
There’s a wide range of essential oil diffuser styles you can try.
A diffuser can be as simple as putting a drop of oil on a cotton ball or using diffuser reeds.
On the other end of the spectrum there are ultrasonic humidifying and ionizing electronic diffusers.

Cooking with Essential Oils

While you should never take essential oils internally in their undiluted form, if you buy “food grade” essential oils you can actually incorporate them into your recipes.
If this idea intrigues you, check out the essential oil recipes in How to Cook with Essential Oils.
Be sure to try the healthy Lavender Lemonade recipe for a delicious way to stay cool and calm.

How to Create Your Own Essential Oil Blends

Lastly, when using essential oils feel free to mix and match.
Unlike herbal remedies where certain ingredients should not be taken together (i.e., 5-HTP and St. John’s wort), with essential oils you can mix and match to your heart’s content.
You can buy essential oil proprietary blends for anxiety or stress.
They usually have soothing names like “Destress,” “Relaxation,” “Serenity” or “Calm.”
(I use a pre-blended mix of lavender and chamomile by Aura Cacia called “Chill Pill.”)
When mixing your own essential oil blends you can hardly go wrong.
In fact, mixing essential oils often increases their effectiveness by allowing them to work synergistically.

There you’ll find instructions on how to create perfect essential oil blends including instructions for your own lavender-chamomile anti-anxiety blend.
