Aromatherapy is the use of essential oils to support physical health and well-being. Essential oils carry biologically active volatile compounds of flowers and plants in a highly concentrated form. They are, in many ways, the essence of the plant and can provide therapeutic benefits in very small amounts.
The particles in essential oils, which come from flowers, twigs, leaves, or bark, can be inhaled, prompting various beneficial effects. As noted by the National Association for Holistic Aromatherapy (NAHA):1
"It [Aromatherapy] seeks to unify physiological, psychological and spiritual processes to enhance an individual's innate healing process."
There are about as many uses for aromatherapy as there are essential oils, but one of the most exciting areas of research is for anxiety, with research showing essential oils may help relieve symptoms without the side effects of anxiety drugs.
Aromatherapy May Help Lessen Anxiety Naturally
For an estimated 40 million US adults, feelings of anxiety may occur even when there's no real threat, causing unnecessary stress and emotional pain.
Unfortunately, most people who suffer with anxiety either do nothing or resort to pharmaceutical drugs – many of which are ineffective and capable of destroying your health and sanity further. Commonly prescribed drugs include benzodiazepine drugs like Ativan, Xanax, and Valium.
Many of these anti-anxiety drugs exert a calming effect by boosting the action of a neurotransmitter called gamma-aminobutyric acid (GABA) in the same way as opioids (heroin) and cannabinoids (cannabis) do.
This in turn activates the gratification hormone, dopamine, in your brain. Since the identical brain "reward pathways" are used by both types of drugs, they can be equally addictive and also may cause side effects like memory loss, hip fractures, impaired thinking, and dizziness.
Ironically, the symptoms of withdrawal from many of these anxiety medications include extreme states of anxiety – some of which are far worse than the original symptoms that justified treatment in the first place. Clearly a safe, natural alternative for treating anxiety is needed, and aromatherapy may be one such option worth trying. Research shows:
- A systematic review of 16 randomized controlled trials examining the anxiolytic (anxiety-inhibiting) effects of aromatherapy among people with anxiety symptoms showed that most of the studies indicated positive effects to quell anxiety (and no adverse events were reported).2
- People exposed to bergamot essential oil aromatherapy prior to surgery had a greater reduction in pre-operative anxiety than those in control groups.3
- Sweet orange oil has been found to have anxiety-inhibiting effects in humans, supporting its common use as a tranquilizer by aromatherapists.4
- Ambient odors of orange and lavender reduced anxiety and improved mood in patients waiting for dental treatment.5
- Compared to the controls, women who were exposed to orange odor in a dental office had a lower level of anxiety, a more positive mood, and a higher level of calmness. Researchers concluded, "exposure to ambient odor of orange has a relaxant effect."6
Which Essential Oils Work Best for Anxiety? (And How to Use Them)
If you're interested in trying out this natural form of anxiety relief, any of the following essential oils would be a good starting point. These are all popular anxiety-inhibiting oils:7
Lavender (Lavandula angustifolia)8 Rose (Rosa damascena) Orange (Citrus sinensis) Bergamot (Citrus aurantium) Lemon (Citrus limon)9 Sandalwood (Santalum album) Clary sage (Salvia sclarea) Roman chamomile (Anthemis nobilis) Rose-scented geranium (Pelargonium spp.)
There are a number of ways to use aromatherapy. If you have a serious condition, you may want to contact an experienced aromatherapist who can help guide you. Certain essential oils can cause photosensitization (making your skin more sensitive to the sun) or allergic reaction and others should not be used on pregnant women, so it's important to be familiar with an essential oil before using it. That said, you can try to use essential oils at home via the following methods:10
- Indirect inhalation of essential oils using a room diffuser or placing drops nearby
- Direct inhalation of essential oils using an individual inhaler with drops floated on top of hot water (this is popular for treating sinus headaches)
- Aromatherapy massage, in which essential oils are diluted in a carrier oil and massaged into your skin
- Applying essential oils to your skin by combining them with lotion, bath salts, or dressings
Anxiety, of course, is only one use for aromatherapy. Other potential uses include:
- Green apple scent for migraines: One study found that the scent significantly relieved migraine pain. This may also work with other scents that you enjoy, so consulting with an aromatherapist might be beneficial.
- Peppermint for memory: The aroma of peppermint has been shown to enhance memory and increase alertness.
- Nausea and vomiting: A blend of peppermint oil, ginger oil , spearmint oil, and lavender oil....11
- Lavender for pain relief: Lavender aromatherapy has been shown to lessen pain following needle insertion.12
Additional Natural Treatments for Anxiety
Energy psychology techniques, such as the Emotional Freedom Technique (EFT), can be very effective by helping you to actually reprogram your body's reactions to the unavoidable stressors of everyday life. This includes both real and imagined stressors, which can be significant sources of anxiety. EFT is akin to acupuncture, which is based on the concept that a vital energy flows through your body along invisible pathways known as meridians. EFT stimulates different energy meridian points in your body by tapping them with your fingertips, while simultaneously using custom-made verbal affirmations. Although not necessary, you can even use EFT along with aromatherapy if you like.
This can be done by yourself or under the supervision of a qualified therapist, either in person or via online video services, like Skype, FaceTime, or Google Hangouts. In the following video, EFT therapist Julie Schiffman discusses EFT for stress and anxiety relief. Please keep in mind that while anyone can learn to do EFT at home, self-treatment for serious issues like persistent anxiety is dangerous and NOT recommended.
It is dangerous because it will allow you to falsely conclude that EFT does not work when nothing could be further from the truth. For serious or complex issues, you need someone to guide you through the process, as it typically takes years of training to develop the skill to tap on and relieve deep-seated, significant issues.
If you suffer from anxiety, it would be wise to look into nourishing your gut flora, and the best way to do this is to regularly consume traditionally fermented foods, which are naturally rich in beneficial bacteria. Pasteurized versions will NOT have the same benefits, as the pasteurization process destroys many, if not all, of the naturally occurring probiotics. So you will need to seek out traditionally fermented, unpasteurized foods like fermented vegetables, or make them yourself. Additionally, your diet should include a high-quality source of animal-based omega-3 fats, like krill oil. The omega-3 fats EPA and DHA play an important role in your emotional well-being, and research has shown a dramatic 20 percent reduction in anxiety among med students taking omega-3s.13
In addition to the creation of new neurons, including those that release the calming neurotransmitter GABA, exercise boosts levels of potent brain chemicals like serotonin, dopamine, and norepinephrine, which may help buffer some of the effects of stress. Many avid exercisers also feel a sense of euphoria after a workout, sometimes known as the "runner's high." It can be quite addictive, in a good way, once you experience just how good it feels to get your heart rate up and your body moving.
If you struggle with anxiety, you really can't go wrong with starting a comprehensive exercise program – virtually any physical activity is likely to have positive effects, especially if it's challenging enough. That said, Duke University researchers recently published a review of more than 100 studies that found yoga appears to be particularly beneficial for mental health,14 although I also recommend high-intensity interval training like Peak Fitness and resistance training, in addition to flexibility and core-building exercises like yoga or Foundation Training.
