What is Aromatherapy?

In the simplest terms, aromatherapy is a holistic healing practice that involves using plant extracts to achieve a specific response, such as relaxation, pain relief, improved mood, headache relief and so on. The plant extracts are often put into oil form, which you likely know of as essential oils, making it easy to use the medicinal properties of these plants. However, aromatherapy can also consist be used in any way that allows you to benefit from the scent of the plant. For example, smelling dried buds of lavender can also be considered aromatherapy.

Since it is a holistic practice, aromatherapy can be used to enhance your physical health, as well as your emotional, mental and spiritual health.

Aromatherapy used to be considered “woo-woo” but it has been gaining recognition in both the science and medical fields, with many studies confirming the benefits it can offer for your mind, body and spirit.

What are Essential Oils?

Essential oils come from various parts of plants, such as flowers, herbs, barks, roots, peels, and petals. The “essence” of a plant is its scents, which is extracted and turned into an essential oil.  

The production of essential oils requires a considerable amount of plant extracts. For instance, it takes over 200 pounds of lavender flowers to produce just one pound of lavender essential oil.

Some examples of types of plants used for aromatherapy are:

  • Herbs, such as thyme and rosemary
  • Grasses, such as lemongrass
  • Fennel seeds
  • Leaves from eucalyptus plants
  • Zest from fruits, such as oranges and lemons
  • Flowers, such as geranium, lavender and rose
  • Bark or wood from trees, including cedar and fir
  • Roots from ginger
  • Resin from trees, such as frankincense trees

It’s also worth mentioning that not all products that are made with a plant’s fragrance can be considered essential oils. In order for a product to be deemed an authentic essential oil, it has to be pure and free of any synthetic chemicals or artificial fragrances. They must also be manufactured using a specific method that preserves the natural chemistry (and medicinal properties) of the plant.

How does Aromatherapy work?

It comes down to science. Aromatherapy is the practice of using essential oils for therapeutic purposes, which are provided to you through scent, hence the name aroma-therapy. As you inhale the scent of the plant extract, which is common in the form of essential oil, the scent molecules travel from the olfactory nerves, which are responsible for your sense of smell and go directly to the brain. Here, the molecules impact different parts of the brain, especially the amygdala, which is the emotional center of the brain.

You can also inhale the essential oils, which works similarly to the prior. As you inhale the aroma of these plant extracts, the molecules get absorbed by the body. This method is particularly beneficial for the respiratory system, especially when used with essential oils that have antibacterial and antiviral properties that aid with a healthy respiratory system.

The practice of aromatherapy can also involve absorbing the essential oils and the medicinal properties through the skin. This works a little differently than the prior, for obvious reasons. Instead of the molecules traveling through the nose, they penetrate through the top layer of your skin to reach a deeper layer called the dermis. From there, they enter the bloodstream through blood vessels, and circulate throughout the body.

What can aromatherapy be used for?

Aromatherapy can be used for a plethora of physical, mental, emotional and spiritual ailments and goals. This is because the majority of essential oils have antibacterial properties, with many also having antiviral, anti-fungal, and/or anti-inflammatory properties. As such, they can be used to for everything from stress relief and relaxation to joint and muscle pain, respiratory infections, PMS and menopause symptoms, skin disorders, blood sugar fluctuations, fatigue and much more. While scientific studies are being done to prove the benefits of essential oils for a variety of different ailments, research has shown that essential oils can help with:

  • Stress relief
  • Easing anxiety
  • Helping depression
  • Improving sleep
  • Helping with sleep disorders
  • Boosting relaxation
  • Inducing calming
  • Improving quality of life for people with dementia
  • Soothing pain, from headaches to pain caused by kidney stones and osteoarthritis
  • Fighting off bacteria
  • Easing side effects of cancer treatment
  • Increasing appetite
  • Treating nausea
  • Helping dry mouth

Different Ways to Use Aromatherapy

One of the most common ways to use essential oils is through inhalation, either by direct sniffing from the bottle or by adding a couple of drops of essential oil into a diffuser or humidifier. You can also dilute the essential oil with a carrier oil, such as coconut oil and apply it directly to the skin or mix a couple of drops with your body wash, shampoo, or bath to add an extra dose of therapeutic benefits. Here’s a quick recap with some other ways to use aromatherapy include:

  • Add a couple of drops into a diffuser or humidifier
  • Smell the scent directly from the bottle
  • Combine with a carrier oil and apply to your skin
  • Add the essential oil to your favourite products
  • Add a couple of drops to your bath
  • Wear aromatherapy accessories, such as necklaces, bracelets and keychains that have an absorbent material for you to add essential oils to

However, it’s important to know that not all essential oils can be used the same. For example, some essential oils shouldn’t be applied topically. As such, it’s crucial to research the specific essential oil you plan on using to find out how to do so properly.
