Here at Marie Claire UK, we're big fans of essential oils for stress, never without a peppermint or bergamot oil on our desks or in our bags. While they're essentially just plant extracts, research has found that they have the potential to both boost mood and relieve tension.
While the studies are promising - one John Hopkins paper concluded that some essential oils can kill one type of Lyme bacteria - it's important to point out that results in human trials are mixed and they haven't conclusively been found to be effective as of yet. Rather, the science indicates that they can be beneficial in promoting relaxation, easing tension and more - and, of course, they smell incredible.
Meghan Markle and Miranda Kerr are reportedly fans of a good essential oil and we're not surprised - in a perpetually stressful world, knowing the signs of stress and how to combat them is key.
Stats do the talking, really: one in five of us across the country feel as though our mental health and wellbeing have declined in the last year, according to research from Kalms. But fun fact for you: alternative therapies, such as using essential oils in your day-to-day, have been used to promote wellbeing for centuries. "The use of essential oils is an ancient practice," shares Simone Stevens, expert aromatherapist (MFHT CHNC registered), on behalf of Tisserand Aromatherapy. "There are references as far back as 4500 BC, and Ancient Egyptians using aromatic oils in cosmetics and ointments."
Using the best essential oils is one of the easier alternative therapies - all it requires is a spritz on your way out the door or a dab on your wrist to help you unwind. If you've ever attended a yoga class or spa day, you've likely had the pleasure of being introduced to an essential oil or two.
So, keep reading as our expert team of aromatherapists help explain the different essential oils, plus share their personal favourites. It goes without saying that no two essential oils are the same - each different oil and scent is used for a different purpose. Time to hand it over to the aromatherapy experts.

Your complete guide to the essential oils for stress, plus the expert's favourite
What are essential oils?
In short, essential oils are highly concentrated liquids extracted through distillation or manual methods like cold pressing. "Essential oils are plant essences that can be used in multiple ways to boost health and wellness," explains Tipper Lewis, naturopathic herbalist and head trainer at Neal's Yard Remedies.
"Essential oils are the oil form extracted from plants, fruits, barks, herbs, and leaves - the natural chemicals that give the plant its “essence”, its specific odour and scent. They're often described as the DNA of the plant," continues aromatherapist Simone Stevens.
So, how are they made? Simple - "by steaming or pressing the parts of a plant to capture the compounds that produce fragrance," Lewis explains.
How do they work, we hear you ask? "Essential oils work on the limbic part of the brain - the part of the brain that's responsible for our primary responses, like memory, your fight or flight response, and sexual attraction," she adds.
How do essential oils work?
As Stevens explains, there are a few ways in which essential oils work, but they're largely either inhaled (think spritzed in the air or on a pillow) or via topical application (rolled on your wrists).
"When inhaled, the scent molecules in essential oils travel from the olfactory nerves directly to the brain and are thought to impact the amygdala, the emotional centre of the brain," Stevens shares.
While they can be diluted and used on the skin to help with anything from acne to dehydrated skin, our experts reckon it's when you smell them that you really reap the mind-body benefits.
"Studies have shown that essential oils are absorbed by smell receptors in your nose that are linked to the limbic system – the part of the brain controlling our emotional responses," says Dr Anna Persaud, a biochemist and CEO of This Works. "This, in turn, can impact heart rate, blood pressure and the nervous system."
How do you use essential oils?
Despite being natural, essential oils are still potent and should be used judiciously, share our pros. A diffuser is the most common way of releasing them into the air.
"If you're looking to inhale essential oils, you can use a diffuser or candles that are made of pure essential oils," explains Stevens.
There is the option of a rollerball too - a favourite of team MC UK. "Apply the rollerball to your wrists and palms before cupping them over your face. Then, breathe deeply for five seconds," recommends Noella Gabriel, president of spa brand Elemis.
You could also try using a calming pillow mist, often a blend of flower waters, herbs and essential oils that promise to provide a better quality night's sleep. Or ""combine with oil or balm for massage" suggests Charlotte Vøhtz, founder of Green People and Alexandra Kay wellbeing.
Top tip: make sure that you always look for blends created with 100% essential oils and be cautious of vague, unregulated terms on the label like "therapeutic grade" and "fragrance oil."
