A peek into aroma families: 8 major categories of essential oils

Essential oils are sources of great well being. An essential oil is nothing but a plant extract which is concentrated and highly rich in healing and aromatic properties. Often volatile liquids, these essential oils contain small oil-like molecules produced by plants during photosynthesis. It is these extracts which are present in plant cavities like roots, petals, seeds and peels, that protect the plant from various infections, parasitical hindrances and other environmental issues, making it grow without trouble. The same valuable volatile liquids act wonderfully to prevent and treat ailments in human beings too. This makes them special and this is why these essential oils are used to heal/prevent/treat many health disorders in people.


Aroma families: There are a whole range of essential oils in the market. Some are grouped as just fragrances, some act as herbal liquids, while some serve the purpose of treating ailments. One classification of essential oils is based on notes – Top Notes, Middle Notes and Base Notes.

Essential oils classified under Top Notes normally evaporate faster and tend to be more antiviral, invigorating and refreshing. They are highly volatile and hardly last long. However, they make their mark with their aromas and light nature. Middle Notes oils have a balancing effect and normally take a couple of minutes to establish their scents. This is because they are warm and soft fragrances which are a bit heavy than the Top Notes variants. Base Notes essential oils are very solid and strong in their aromas. They last a long time and even slow down the evaporation of the oils mixed with them. Heady fragrances that relax the body mark the Base Notes category.

There is also yet another way of classifying essential oils other than the one based on Notes. A broader classification can be made based on the aromas of the oils.
