Depression affects millions around the world. And depression medications come with side effects that worry many. For these, there is new hope: Aromatherapy.

Really? Aromatherapy for depression?

We have already discussed aromatherapy for fighting candida, soothing seasonal allergies, premenstrual symptoms and improving heart health. Now we’re talking clinical depression.

For decades, depression has been treated with serious medications. These include tricyclic antidepressants, serotonin-norepinephrine, selective serotonin reuptake inhibitors and monoamine oxidase inhibitors. Yet many of these don’t work that well. They can also come with serious side effects. These include insomnia, nervousness, drowsiness, dizziness, nausea, erectile dysfunction and diarrhea. Depressing stuff.

More than 350 million people around the world have been diagnosed with depression. It is one of the greatest causes of disability. By 2030, depression is projected to be the number one cause for disability.

So is there any real evidence that simply breathing in the aroma of an essential oil can treat depression? You betcha.

Evidence for aromatherapy for depression

A review of research published in the 2017 Evidence-Based Complementary and Alternative Medicine journal found over 500 studies on the topic during their investigation. After screening out studies that were not clinically based or qualified for other reasons, they found 12 randomized clinical trials that tested aromatherapy for depression.

The 12 studies included a total of 1,226 men and women. Some of the participants had other conditions such as cancer, pregnancy or menopause. Some of the women included in the research had postpartum depression.

The treatments of the studies included the following essential oils:

• Mixture of lavender, bergamot and cedarwood
• Mixture of rose and lavender
• Mixture of lavender, pititgrain and bergamot
• Yuzu (Japanese citrus fruit)
• Lavender
• Mixtures of bergamot, lemon clary sage, lavender, roman chamomile, geranium, rose, sandalwood and jasmine
• Mixture of Melissa, juniper and rosemary
• Mixture of rose and lavender
• Mixture of lavender, geranium, rose and rosemary
• Mixture of lavender and geranium

Treatments ranged from every day to once every two weeks weekly. Some of the treatments included inhalation therapy alone. Others included aromatherapy massage. This is when a small amount of the essential oils are blended with a massage oil.

For the inhalation aromatherapy, the diffuser timing ranged between 5 and 20 minutes.

The researchers concluded after their meta-analysis:

“In the overall analysis carried out, aromatherapy showed potential to be used as an effective therapeutic option for the relief of depressive symptoms in a wide variety of subjects.”

Inhalation aromatherapy

Two studies that used inhalation therapy decreased depressive symptoms. This means they simply breathed in diffused essential oils for a few minutes each session. One was a 2014 study that used the Yuzu citrus fruit essential oil among 20 women.

A 2012 study on 28 women who were postpartum found that a blend of rose otto and lavandula angustifolia essential oils significantly improved their depression and anxiety scores.

Massage aromatherapy

Five of the studies using massage aromatherapy significantly decreased depression symptoms. This means they were given massages using massage oils that were blended with essential oils.

In one, 32 depression patients were treated at the Surrey Oaklands NHS Trust’s Day Hospital. The essential oils were chosen based upon each patient’s symptoms. The results indicated a significant improvement of depression scores, using the Montgomery-Asberg Depression Rating Scale (MADRS) or the Tyrer Brief Anxiety Scale (TBAS).

In a 2011 study, aromatherapy massage was used with cognitive behavioral therapy with 63 patients with depression and/or anxiety. The treatment resulted in significant improvement in scores among the patients receiving the aromatherapy.

In a 2013 study, 90 menopause patients with depressive symptoms were treated with aromatherapy massage or massage without aromatherapy. The massage-only group showed some improvement in symptoms. But the aromatherapy massage group showed significantly more improvement in psychological scores.

In a 2014 study of 25 depressed patients, some received aromatherapy massage for 40 minutes twice a week for four weeks. Those patients scored significantly higher in the Stat-Trait Anxiety Index, Beck Depression Inventory and the Short Form of Psychosocial Well-being Index. They also showed improvements in their brain waves, cortisol levels and levels of brain-derived neurotrophic factor (BDNF).

Physical changes from aromatherapy

While depression can also indicate an missing element related to our spiritual life, our moods are also regulated by hormones and neurotransmitters.

The results of these studies illustrate that aromatherapy can have serious changes on our moods, yes. But they also show aromatherapy affects the production of particular hormones and neurotransmitters. More importantly, those that adjust and regulate our moods. In the 2014 study above, the researchers concluded:

“These results suggest that aromatherapy massage could exert significant influences on multiple neurobiological indices such as EEG pattern, salivary cortisol and plasma BDNF levels as well as psychological assessments.”

Most productive essential oils

The research also illustrated that some essential oils are better for certain issues. Their analysis found that lavender, bergamot and sandalwood provided significant benefit for depressive symptoms. And the Yuzu citris oil “alleviates negative emotional stress.” Most of the other oils used in the various studies have been found to have anti-anxiety and sedative properties.

Talk with your doctor before embarking on the use of essential oils.

Certainly, trying out several different types of essential oils for inhalation comes with little risk. Blending essential oils into a massage oil should be considered carefully, because of the contact with our skin. Using a very tiny amount with a base oil is advisable. One or two drop into a few ounces of jojoba or grapeseed oil should suffice. If multiple oils are used, one drop is better. Blending more than two or three essential oils together can also be problematic for a massage oil. Unless you really know what you are doing.

It’s also best to test the blended oil on a small area of skin before using it to do a full massage. Let it sit for several hours to make sure you don’t react to that oil.

Note that we’ve also discussed the evidence for St. John’s Wort and depression.

All of this is best done after discussions with your doctor or other health professional. And don’t stop any medications without first talking with the doctor who prescribed them.

As I drove home that night, I realized I needed to get this knowledge out to more people. So I began writing about health with a mission to reach those who desperately need this information.
