Aromatherapy is a natural therapy that promotes physical and mental health using essential oils derived from plant essences. This ancient wisdom is gaining increasing attention in our modern, stress-filled society. This guide provides a comprehensive overview of aromatherapy, from basics to practical applications, incorporating the latest research trends.
Principles and History of Aromatherapy
Aromatherapy harnesses the healing power of plant essential oils. Its origins trace back to ancient Egypt, with various cultures recognizing the power of scents throughout history. Modern aromatherapy was systematized in the 1920s by French chemist René-Maurice Gattefossé.
Essential oils are volatile aromatic compounds extracted from plant leaves, flowers, bark, and peels, each with unique scents and properties. These oils are believed to balance body and mind when inhaled or applied to the skin, affecting the nervous and endocrine systems.
Recent research suggests that essential oil components may directly influence the brain through olfactory receptors, potentially affecting neurotransmitter secretion. For instance, linalool, a main component of lavender, may induce relaxation by acting on specific neural receptors. However, these findings require careful interpretation and further verification.

Safe Usage and Precautions
- Importance of Dilution:
Avoid using most essential oils undiluted; always dilute with a carrier oil. A general dilution rate is 1-3%.
Carrier oils are plant-based oils used to dilute essential oils. Common examples include jojoba oil, sweet almond oil, and coconut oil.
- Patch Test:
Always perform a patch test before using a new essential oil. Apply the diluted oil to a small area of skin and observe for 24 hours to check for any inflammation or itching.
- Caution for Pregnant Women and Children:
Extra care is needed when using essential oils on pregnant or breastfeeding women and infants. Some oils should be avoided; consult a specialist.
- Prohibition of Internal Use:
Essential oils are highly concentrated; never ingest them. If accidentally swallowed, seek immediate medical attention.
- Phototoxicity Awareness:
Some citrus oils (lemon, orange, bergamot) may cause phototoxicity. Avoid sun exposure for 12-24 hours after applying these oils.
Phototoxicity refers to skin reactions like dermatitis or pigmentation caused by exposure to UV light after applying certain substances to the skin.
- Interactions:
Some essential oils may interact with medications. Consult a doctor or pharmacist if you’re taking prescription drugs.
- Storage:
Store essential oils in light-blocking containers away from direct sunlight and high temperatures. Keep out of reach of children.
- Quality Check:
Choose products from reliable manufacturers and ensure they are 100% natural essential oils. Avoid synthetic fragrances or diluted products.
Recent studies have reported potential antibacterial properties in some essential oils. Tea tree and eucalyptus oils, in particular, have gained attention for their antibacterial effects against various bacteria. However, consult a medical professional before using these oils for medical purposes. Further research is needed to determine the extent of antibacterial effects and clinical efficacy.
