Definition – What are essential oils?
Essentials oils are extracted from plants, and are known as ‘essential’ as they capture the ‘essence of’ the plant’s fragrance.
In other words, they are concentrated plant extracts.
Essential oils aren’t just used in aromatherapy, they are also used in perfumes, cosmetics, soaps, for flavoring in food and drink, and also for adding scent to various products.
Essential oils are usually sold to individuals in very small bottles. They can vary significantly in quality and price, and different factors come into play here determining how much an essential oil will cost.
- The rarity of the plant/botanical
- Country of origin
- Growing/climate conditions
- Quality standards
- How much oil the plant/botanical produces
Production of essential oils
Essential oils are produced in different ways that can depend on the plant being used or what works best for purpose.
We’ll now go through a few more common ways essential oils can be produced:
The most common essential oils such as lavender, tea tree, and eucalyptus, are obtained by distillation.
The raw plants are put into distillation apparatus over water. As the water is heated, steam passes through and vaporizes the volatile compounds. These vapors then flow through a coil, where they condense back to liquid, and voila, you have your essential oil.
This is common for oils derived from citrus peel, where the oils are cold-pressed. Due to large oil quantities in citrus peel and low growing costs, these oils tend to be cheaper than most other essential oils.
This method was also the more traditional method of extracting essential oils, before distillation was discovered.
For plants that are too delicate for the heat of distillation, or contain too little oil for expression, sometimes a solvent can be used to extract the oils.
Popular types of essential oils

But for this article, we’ve listed a few examples of common essential oils below:
