History of Essential Oils

History states that the human civilization originated in Egypt. Ancient Egyptians ate heartily and used aromatic fragrances to lift their mood.

Sure that’s a great way to bolster positive thoughts. In fact, they were the first ones to use paper, although they called it “papyrus” then. The reeds that grew by the River Nile were harvested and processed into what we know as the earliest history or paper. We are not quite sure, however, if they were the first ones to use ink.

Like paper, essential oils have been traced to ancient Egyptian civilization. Distillation pots dating as far back as 3500 BC were found at the excavation site of the ancient civilization. It was discovered that they used solvent extraction using animal fat as a medium to extract and hold essential oils.

We are going to unearth a wealth of information for you. Let’s visit a few other places that were in on essential oils long ago. 

  • Around the same time as Egypt, China & India also invested in aromatic herbs and plants. Remember, these two countries are probably among the earliest civilizations in human history.
  • The ancient Greeks absorbed the knowledge of essential oils, especially aromatherapy, from the ancient Egyptians. They, however, improved their produce to include massages (Hippocrates 460-377BC).
  • Just like the knowledge of essential oils was passed down to the Greeks by the Egyptians, the Romans also received the knowledge of essential oils from the Greeks. The Romans were highly interested in baths and did every other thing that screamed “hygiene”, and so they birthed the idea of aromatic baths.

Precautions for Usage of Essential Oils

Just like every good thing must come to an end, essential oils have their quirks. They can pose bigger risks when used inappropriately.

  • When taken, applied, or exposed to large doses of the oil in its concentrated form.
  • Essential oils have also been found to be harmful to pets. So, if you have a pet, for example, a cat or dog, here are some essential oils to keep off – tea tree, thyme, clove, and peppermint.

Extraction of Essential Oil

Generally, essential oils are extracted by distillation. Other methods of extracting essential oils are:

  • Solvent extraction.
  • Absolute oil extraction.
  • Resin tapping.
  • Wax embedding.

These methods are only a few ways through which essential oils can be extracted industrially.

Extraction of essential oils at home:

Materials Required:

  • Crock or copper pot.
  • Raw material for intended essential oil I.e. bark or leaves of tree plant.
  • Distilled water
  • Source of heat (stove, cooker etc.)
  • Stopwatch or timer.


  • Thoroughly wash the raw material to remove impurities.
  • Place crock or copper pot on flame. Ensure that the lid on the pot is secured so that when steam collects on the inside of the lid of the pot, the steam goes back to the boiling mixture. Placing the lid of the pot upside down will ensure that steam does not escape.
  • Add distilled water and plant raw material to pot. And turn the heat to high. Ensure that the water in the pot completely covers the plant material placed in it.
  • Leave on high heat until water is hot after which reduce flame to medium-low and leave contents to simmer for 3-4 hours.
  • After 3-4 hours the plant material will be completely cooked and all its contents seeped into the water.
  • Strain the water once it has cooled then, put the container containing the water extract into a refrigerator. Ensure the container is preferably one light cannot pass through.
  • Leave in refrigerator overnight. 
  • By morning, oil residue would have collected on the surface of the liquid due to the low temperature inside the refrigerator.
  • Collect oil fast to prevent melting. Collect in an amber bottle.
  • If water is noticed in the content of the bottle, heat can be carefully applied just long enough for the water to turn to steam and evaporate into the atmosphere.
  • Store in a glass, dark bottle away from heat and light.

Once this is done, your essential oil is ready for use.

Essential Oil Diffusers

Diffusion, in simple terms, is the movement of water vapor from a region of high concentration to a region of lower concentration.

In order to improve the quality of air and the quality of life, it can be seen that introducing essential oil into the atmosphere bears a lot of merit, which brings us around to “essential oil diffusers”.

Essential oil diffusers are devices that help you to disperse essential oils into the air.

There are various types of essential oil diffusers:

1. Ultrasonic Essential Oil Diffuser

With the aid of ultrasonic waves, water is diffused into a a room using this device.


  • It is affordable and readily available.


  • They are fragile and so easily break down.

2. Nebulizer or Atomizing Diffuser

This diffuser type breaks the essential oil on a molecular level, making it readily absorbable by the lungs.


  • There is no delay in the speed at which the essential oil is broken into molecular particles, therefore, the particles still spread across the room at an excellent speed.


  • It is difficult to clean, especially when a really thick essential oil like sandalwood is used.

3. Fan Diffuser

This diffuser type works by blowing air rapidly and breaks the essential oil particles to diffuse across a room.


  • They are portable. Some use electricity and can as well be battery operated.


  • They can be noisy.

4. Electric Heat Aromatherapy Diffuser

As the name implies, this type of diffuser heats the essential oil, leading it to evaporation. This causes effective dispersal of the oil.


  • They effectively disperse the fragrance of thicker essential oils.


  • They are difficult to clean.

Domestic Materials that can be Used as a Diffuser

These household materials have been proven useful in diffusing essential oils. These tricks are handy, especially if you don’t want to invest in a diffuser.

  • Tissue: Place a few drops of the desired essential oil on a tissue. Keep it close enough to the body for it to be smelt and yet far enough to prevent any adverse effect that can be incurred due to close proximity for instance skin irritation. This method is quite effective for close proximity but anything beyond that won’t help. 
  • Steaming or Boiling: Add a few drops of the desired essential oil into water and leave it to steam. As it steams, the fragrance is spread across the room. Note that essential oils are potent and hence, to avoid adverse reactions, the amount of drops incorporated is to be closely monitored. If the concentration is high, it can lead to respiratory difficulties. The fragrance can quickly dispelled into a room but quickly fizzles out.
