Benefits of Different Essential Oils

Essential oils are concentrated oils, extracted from a variety of plants which are traditionally used in natural health therapies. Here we look at 24 of the most popular essential oils, their potential benefits, and how they can be used.

What Are Essential Oils?

Essential oils are compounds that have been extracted from plant leaves, roots and bark. They are called ‘essential’ oils as they retain the plant’s scent and flavour, or ‘essence’. They are highly concentrated and are extracted from the plant by either distillation or cold pressing. Distillation is when water or steam is passed through the plant, removing the essential compounds to make the oil. Cold pressing is when the plant is squeezed to extract the juices and oils.

Sometimes, before they are used, essential oils are mixed with ‘carrier oils’ - this dilutes them so they are kinder to skin (and it also means more product can be made from the same amount of oil). Carrier oils are made of vegetable oils like coconut, or evening primrose.

What Are The Benefits of Essential Oils?

There are many ways that essential oils have been shown to help, including in the following ways:

Improve quality of sleep

Smelling oils such as lavender has been shown to improve sleep quality.

Reduce inflammation

Some essential oils have been shown to have anti-inflammatory properties. More studies on humans are needed, however, but tests on mice have shown that thyme and oregano essential oils helped reduce instances of colitis.

Relieve headaches

It has long been thought that dabbing peppermint oil or chamomile on your temples can reduce headache pain.

Reduce anxiety and stress

Essential oils are often used in conjunction with traditional therapy to relieve symptoms of stress. While more studies are needed to confirm the efficacy of the oils, the scents are often conducive to a relaxed and calming environment.

Boost mood

Essential oils are often used in a therapy environment and can induce a calming, positive and relaxing environment for an enhanced feeling of wellbeing.

Kill bacteria

Again, while more studies are needed on humans, essential oils including peppermint oil and tea tree oil have shown antimicrobial properties. Results have shown this in test tube environments but not yet inside a human body.

How To Use Essential Oils

Essential oils are used in aromatherapy, a healing treatment that uses these natural plant extracts to promote health and well-being (in fact, it is also known as essential oil therapy). Aromatherapy uses aromatic essential oils to enhance both physical and emotional health.

As well as inhaling, massaging essential oils (appropriately diluted) into the skin may also deliver the active compounds to the body. You should never apply essential oils directly to the skin undiluted, unless under the guidance of a healthcare professional.

It is also dangerous to swallow essential oils. Not only are essential oils very concentrated, but they can also irritate cells inside the body.

24 Essential Oils and Their Benefits
