Let’s see what all you need to know about essential oils, be its benefits or uses, but the let’s start with the basics of all of it –


Essential oils were first known to be used by the Egyptians. They incorporated its use in various fields like that of medicinal, religious ceremony, cosmetics, and also for embalming the dead. Later on, its use was spread in the world, and almost in the same era as that of the Egyptians, the Chinese and Indians also started to employ them in medicines such as Ayurvedic medicines.

Just like human beings who can produce a few essential vitamins and essential amino acids that help us grow and maintain our system, plants can also do such activities, and essential oils are the compounds that are made by the plants.

Although plants’ purpose for producing volatile compounds such as essential oils are mainly for its protection from various insects, there have been around 400 plants that have been identified as the producer of essential oils and are thus cultivated today all around the world for commercial sale[1].

Essential oils have a specific taste and odor that are distinctive to a particular plant species. These are compounds extracted from plants.

The oils that are extracted from these aromatic plants are called the “essence” of the plant and, thus, this potent oil carries the essential healing properties of the plant in it.

Most of the time, these are available in a concentrated form, and the concentrated form of the essential oils are very strong in nature and have a higher level of active components in it. Thus, the use of essential oils for health and wellness needs to have some basic knowledge of what they are, how they work, and how to use them.


The making of essential oils actually deferred from company to company, and thus there is no hard and fast rule to use just one necessary process, the most common methods to extract the oils from the plants are :

  • Distillation- This is the most commonly used process for the production of essential oils for health and wellness.

This is used very frequently by the majority of the companies. It involves the use of steam, which carries the essential oils from the plant, and then the steam is filled by the method of distillation.

There are various kinds of distillation processes, as well as steam distillation, hydro distillation, water, and steam distillation.

  • Solvent extraction- This extraction method is used for sensitive and delicate plants or oils, such as Jasmine, Linden, etc. The distillation process is a bit harsh can degrade the compounds.
  • Cold pressing- Cold pressing is also another popularly used method of extraction. They are usually used for essential oils extracted from fruits or seeds of the plant, such as orange essential oils, lemon, and grapefruit.

The process involves using mechanical pressure on the seeds or fruits to pierces it and thus ruptures the cells so that the essential oil oozes out from them.

  • Chemical extraction- This basically involves the use of chemicals to extract the essential oils from the plant parts.

There are about 90 different types of essential oils present today in the market.

The type of process used to recover the essential oil for the health and wellness of our body is quite necessary as it gives us an idea which method is more effective and which would provide a more pure form of the product [2].

For, e.g., the chemical method of extractions is not preferred as the other methods, and thus there are times when the chemically obtained essential oils are not considered as pure essential oils.


There are about 100 different chemical components of an essential oil[], the main categories under which these components fall into are:

  • Alcohols
  • Ketones
  • Phenols
  • Aldehydes
  • Esters
  • Trace elements

Some essential oils may contain more or less than 100 but majority of them have 100 components


The use of plants in this world goes back to the origin of humanity, and since that time, plants have been our way to deal with all the problems of our life. 

Researches have been studying plants, its healing properties and now even essential oils

The therapeutic effects of the oil are limitless and go beyond herbal medicine; These essences are used for healing and mental calmness of our body.  

One of the most common uses of essential oils for health and wellness is by the practice of aromatherapy, which involves inhalation of the essential oils using various methods.

  • It is said that inhaling these essential oils which are full of concentrated active compounds can stimulate our limbic system, the part of the brain responsible for memory and emotions, thereby improving the health of the brain and its networking system[3].

Smells, in general, have always been associated somehow with our memory, either reviving our memories or triggering a cascade of memories and emotion[4].

  • Along with this, the limbic system also has other functions in our body that are involuntary actions such as heart rate, blood pressure.
  • Thus if essential oils somehow improve the health of the limbic system, it indirectly helps to regulate the functioning of the limbic system as well that justifies the claims that are said for its health and physical benefits [5].

Harpreet Gujral, DNP, FNP-BC program director of integrative medicine at Sibley Memorial Hospital once said that:

“When inhaled, the scent molecules in essential oils travel from the olfactory nerves directly to the brain and especially impact the amygdala, the emotional center of the brain.”

-Harpreet Gujral, DNP, FNP-BC

The other prevalent essential oils for health and wellness are its topical use on skin. The science behind the claims of healing acne or treat pain and aches is due to the fact that:

  • As soon as we apply the essential oils on our skin, it being so concentrated and volatile in nature gets absorbed quite easily in our skink and then eventually reaches our bloodstream, the blood carries the active, potent compounds and reaches the liver where they are metabolized, which are beneficial for the body function.
  • Another reason is the potential of the essential oils of being antimicrobial in nature; thus, they can be used to remove any acne infection caused due to microbial growth. 

The research on essential oils can be a bit difficult because, as we know that they are extracted from the parts of the plant, and due to the difference in the soil and nature of the environment all around the world, the composition of the plants can change.

Thus there are no standards of essential oils to work with. The actual nature and cause of the benefits of the essential oils are not yet well explored and need more information; thus, it is necessary to know that there are no scientific facts that have well explored the field yet.

Having said so, there are also works and studies that say otherwise and show the beneficial nature, so it is not totally worthless. Some reviews say that lavender essential oil induces sleep and improves sleep cycle [6].


As mentioned above, there are about 90 different types of essential oils today present in the commercial market, each having its unique features and properties [7].

As it’s not possible for us to go through all the 90 types, here is a list of the top 15 potent essential oils for health and wellness purposes that are well known.
