Aromatherapy: Healing with Essential Oils
Aromatherapy – An Overview of Natural Healing
Aromatherapy, as the word “therapy” suggests, is a complex form of care that uses aromatic essences for therapeutic purposes. These aromatic essences are extracted from plants and are called essential oils. An essential oil is a fragrant, volatile substance produced by aromatic plants. Commonly used parts include the leaves (e.g., eucalyptus or tea tree), flowers (e.g., rosemary, rose), seeds (e.g., fennel, anise, orange), bark and wood (e.g., cedar, sandalwood), and resins.
Extraction methods vary: cold mechanical pressing (enfleurage), chemical or alcohol-based solvent extraction, and most commonly, steam distillation. A single essential oil can contain hundreds of types of molecules, each with specific properties: antibacterial, antiseptic, decongestant, immune-boosting, or calming. These molecules work in synergy, which explains the broad scope of essential oil actions.
A single plant may produce different essential oils from its flowers, leaves, or other parts, with varying effects. The chemical composition of an oil, called its chemotype, is influenced by environmental factors such as sunlight exposure, soil quality, temperature, and weather resistance.
Origins of Aromatherapy
Throughout medical history, aromatherapy was closely linked with phytotherapy (herbal medicine) up until the 15th century. Plants formed the foundation of ancient pharmacopeias. Greek texts by Dioscorides document the use of aromatic extracts. This science developed in India and China, where methods of distillation and extraction were found.
In ancient Egypt, essential oils were widely used. In the 10th century, Persian physician and alchemist Jabir Ibn Hayyan invented the alembic, improving distillation techniques, later refined in the 16th century.
In the 20th century, French chemist René-Maurice Gattefossé coined the term “aromatherapy.” After burning his hands, he applied lavender essential oil, with surprising healing results. Convinced of its power, he dedicated his work to studying essential oils. In the 1960s, Dr. Jean Valnet expanded on his research and published several books. Together, they are considered the founding fathers of modern aromatherapy. Later, Pierre Franchomme, a pharmacologist, improved the understanding of active compounds through the notion of chemotypes.
Benefits of Aromatherapy
Dozens of essential oils have shown direct actions on metabolism, physiological functions, and pathogenic microorganisms. Their known properties include anti-inflammatory, antispasmodic, analgesic, anti-itch, cholagogue, and cholerectic effects.
Although clinical proof is still limited, many studies and real-world use suggest strong therapeutic potential. For example:
Hospital patients reported reduced anxiety after aromatherapy treatments.
A 2005 study found lavender oil acted as a mild sedative, promoting deep sleep.
A combination of lavender, marjoram, ylang ylang, neroli, bitter orange with jojoba and sweet almond oil may help reduce high blood pressure.
Cumin and cinnamon essential oils may help lower type 2 diabetes blood sugar levels.
Essential oils have shown synergistic effects with antibiotics in treating resistant urinary infections.
They’re also used to ease menopause, premenstrual symptoms, and cystitis, and to mitigate radiation therapy side effects. For instance, niaouli oil can reduce radiodermatitis, improving healing post-irradiation. Oils like tea tree, oregano, and clove have antimicrobial power, helpful against hospital-acquired infections.
Studies continue to explore aromatherapy’s effects on eczema, respiratory infections, arthritis, multiple sclerosis, fibromyalgia, epilepsy, depression, and Alzheimer’s disease—though more evidence is needed.
