The essential oil and the aroma produced by a plant in nature allow it to defend itself against parasites of various kinds and to heal its own tissues, regenerating itself.
In the same way, essential oils perform their reparative action also against the human body . Furthermore, perfumes, acting on hypothalamus and pituitary gland, allow to influence the hormonal production of human beings.
Let's find out how essential oils are classified based on the olfactory note.
The 3 groups of essential oils
The subdivision of essential oils into 3 groups was carried out in the 19th century by GW Piesse, a scholar who grouped essential oils from various plants. Essential oils are divided into 3 groups according to the olfactory note they present.
Base note
The essential oils belonging to this group have a low, deep or heavy aroma of earth and bark. They evaporate over a long period of time and act primarily on the physical plane, reconnecting to the earth.
From an emotional and mental point of view they stabilize, rebalance, calm . An example of a very strong base note is the essential oil of Vetiver, with its hint of earth, as well as the essential oil of Patchouli, and the essential oil of Sandalwood, woody and heavy.
