Aromatherapy relies on three methods of administering essential oils, each suited to different indications and profiles. The atmospheric route (diffusion) is the most accessible: essential oils are vaporized into the air and inhaled through the respiratory tract—ideal for effects on mental well-being (stress, sleep, concentration), respiratory infections, and air purification. Topical application (external application diluted in a vegetable oil) allows for local or systemic penetration of the aromatic molecules—recommended for muscle pain, skin conditions, and massage. Oral administration is reserved for specific cases and must be supervised by a healthcare professional—Puressentiel neutral tablets allow one to two drops of essential oil to be placed on a solid base before ingestion, limiting the risk of irritation to the digestive tract mucosa. Noble laurel essential oil is one of the essential oils traditionally used orally for its antiviral and immunostimulant properties.
The choice of diffuser determines the effectiveness and safety of atmospheric diffusion. An ultrasonic diffuser (water + ultrasonic waves) produces a finely atomized mist—less concentrated than a nebulizer but economical in terms of essential oil use and suitable for small spaces and children. A nebulizer (water-free, mechanical spray of pure essential oil) produces a more concentrated and therapeutically active diffusion—best used in well-ventilated spaces and by adults. The gentle-heat diffuser (Puressentiel Calvi) gently heats the essential oil without altering its properties—compact and quiet, making it ideal for workspaces. Portable diffusers (Pranarom Soleo Gris, Phytosun Easygo, USB or AC-powered) are convenient for the office, the car, or when traveling. Ready-to-diffuse blends (Phytosun Woody Floral Complex, Pranarom Festive Spirit) are the ideal solution for beginners—with pre-balanced proportions and guaranteed aromatic effectiveness.Incense (Olibanum resin, Boswellia sacra) is a time-honored alternative to electric diffusers for purifying and soothing indoor spaces.
Hydrosols (floral waters or aromatic waters) are the aqueous byproducts of steam distillation of plants—less concentrated and less irritating than essential oils, they offer a gentle introduction to aromatherapy, particularly suitable for children, pregnant women, and those with sensitive skin. Pranarom Organic Orange Blossom Hydrosol (150 ml) is the most versatile option for beginners: spray it on your face (for hydration and soothing), mist it on your pillow (for sleep), add it to your bathwater (for relaxation), or use it as a light lotion.Helichrysum (Helichrysum italicum) is a valuable essential oil in advanced aromatherapy for its regenerative and healing properties—its hydrosol is particularly gentle on mature and sensitive skin.
Ready-to-use products are the best way for beginners to get started. The LCA Anti-Stress Roll-On (10 ml, bergamot + lavender + marjoram + petitgrain bigarade in a carrier oil base) is applied directly to the wrists, temples, and solar plexus—no prior dilution required, and no risk of error. Puressentiel Aroma Stress Gummies (45 gummies, saffron + lavender essential oil + melatonin) combine aromatherapy and nutraceuticals for daily stress management and sleep preparation. Wintergreen (96–99% methyl salicylate) is an iconic essential oil whose roll-ons are widely used in sports for muscle pain—never use it undiluted due to its extremely high salicylate concentration.
Essential oils are powerful concentrates—there are a few fundamental rules every beginner must follow:
Immortelle (Helichrysum italicum) and clove (eugenol 70–85%) are two powerful essential oils that must be diluted—clove is dermocaustic in its pure form and must always be diluted to less than 0.5% for topical applications.
