Abstract
The history of aromatherapy begins over 3500 years BC. Aromatics were at
the time for religious purposes, perfume, and medicine. Then, in 1910, René-Maurice
Gattefossé, a chemical engineer from Lyon, discovered the therapeutic properties of
pure lavender after an explosion in his laboratory, which left him with major burns. He
treated them with lavender essential oil. Won over by that “miracle”, he founded the
French Society of Aromatic Products and published around twenty works that are still
considered references today. These works would give aromatherapy its reputation and
its very name, as it was Gattefossé who coined the term “aromatherapy”, in 1935. He
conducted many rewarding personal and scientific experiments on essential oils. Other
scientists, such as Charles Chamberland, a biologist and assistant to Louis Pasteur, had
already examined their spectacular antimicrobial action. In the 5th century BCE,
Hippocrates was already treating patients with aromatic vapours. Aromatherapy is a
branch of phytotherapy that uses the volatile active ingredients of aromatic plants.
These are plants that have the ability to synthesize an essence. This science focusses on
the use of essential oils for therapeutic, curative, or preventive purposes. For the most
part, the essential oils are extracted by steam distillation of parts of the plant (such as
leaves, flowers, or bark). Only the essences of citrus pericarp (such as orange or
mandarin zest) tend to be obtained via mechanical cold pressing. In 1929, Sévelinge, a
pharmacist from Lyon, demonstrated the antibacterial efficacy of certain essential oils.
Then, in the 1950s, a military physician used them to treat injured soldiers in Indochina. In 1975, Pierre Franchomme, a pharmacologist and aromatologist, brought about
decisive progress by proposing that the concept of “chemotype”, the “plant’s true
chemical ID card”, should be taken into account, listing the key aromatic compounds
characterizing each plant and how they affect its properties. Today, aromatherapy is
more frequently the focus of scientific studies. It is recognized as a fully-fledged
branch of medicine. Over 17,000 articles on aromatherapy have appeared in an
international high-level scientific publications.
