What Are Essential Oils?

Essential oils are natural products extracted from raw plants. The oils capture the plant’s own “essence.” What gives every essential oil its distinctive essence are the unique aromatic compounds produced by the plants.

These oils usually have a more pungent smell than the plants they’re extracted from and have higher active ingredients, affected by the particular amount of plant matter needed to produce essential oil.


Essential oils are extracts of different— possibly beneficial— plants. A lot of these plants may contain likely beneficial compounds. However, there is no sufficient evidence to recommend using them as a cure or treatment for ailments.

Ways to Extract Essential Oils

Various manufacturing processes can extract beneficial compounds from plants. Manufacturers obtain essential oils through different methods of extraction.

The different ways of extracting essential oils include:

1. Water or Steam Distillation

This method passes hot steam or water over the plants, pulling away the essential compounds from the plant matter.

2. Cold Pressing

This process involves mechanically squeezing or pressing plant matter, causing it to release essential oils or juices. One such example is smelling the fresh fragrance of lemon after zesting its peel or squeezing it.

After extracting the plant matter’s active compounds, select manufacturers produce more products from an equal amount of essential oil by adding the compounds to carrier oil. With this, the products are turned into a mixture and are no longer pure essential oils.

Uses of Essential Oils

Essential oils are manufactured to produce a variety of products. The makeup and cosmetic industry use essential oils to add fragrance to body creams and washes, create perfumes, and as some beauty products‘ source of natural antioxidants. You can also smell fresh with great cologne options such as the luxury brands Coty, Chanel and Burberry.

A lot of natural medicine practitioners, like the aromatherapist, utilize essential oils. In aromatherapy, essential oils are diffused into the air.

Aromatherapists assume that breathing in oils might make them enter the bloodstream and lungs, making the body benefit from some of the potentially beneficial compounds.

The usage of a mentholated vapor rub for clearing the sinuses is also a method of aromatherapy. A 2013 study from studyTrusted Source notes that this way of inhaling menthol reduces shortness of breath and feelings of congestion.

Combining essential oils with a carrier oil and massaging them onto the skin may also work as well as inhaling them when it comes to providing active compounds to the body.

It’s not advisable to apply essential oils directly to your skin without diluting them first unless it’s under the personal supervision of a healthcare professional.

It’s also harmful to consume essential oils as they are highly concentrated and can irritate the internal body’s sensitive cells.

In some unusual cases, some people might be asked to take oral capsules with essential oils. However, you should only do this if you’re under the direct supervision of a healthcare professional.

Although, usually, you should not place any regular commercial essential oils anywhere nearby your eyes, ear, mouth, vagina, anus, or in any other areas where they can enter your body.
