Aromatherapy Applications Flashcards

How does inhalation aromatherapy work?

Answer: Volatile molecules stimulate olfactory receptors, sending signals to the limbic system which influences emotions and physiological responses

When inhaled, essential oil molecules stimulate olfactory nerve receptors in the nasal cavity, sending signals to the limbic system (amygdala, hippocampus), which influences emotions, memory, stress response, and certain autonomic functions.

Which essential oil is most commonly associated with relaxation and sleep support?

Answer: Lavender (Lavandula angustifolia)

Lavender (Lavandula angustifolia) is the most researched essential oil for relaxation, with studies showing its primary component linalool has calming effects on the nervous system.

What is a hydrosol in aromatherapy?

Answer: The water-based byproduct of steam distillation, containing water-soluble plant compounds and trace essential oil

Hydrosols (floral waters) are the condensed water collected during steam distillation of plants, containing water-soluble plant compounds and a small amount of essential oil, making them gentle enough for direct skin application.

What is an aromatherapy diffuser and what types are available?

Answer: A device that disperses essential oil molecules into the air; types include ultrasonic, nebulizing, evaporative, and heat diffusers

Diffusers disperse essential oils into the environment. Ultrasonic use water and vibration, nebulizers use pressurized air for pure oil mist, evaporative use fans, and heat diffusers use warmth to volatilize oils.

Which essential oils have documented antimicrobial properties?

Answer: Tea tree, oregano, thyme, and cinnamon have demonstrated antibacterial and antifungal activity in research

Multiple essential oils show antimicrobial activity in laboratory studies. Tea tree (melaleuca) is particularly well-documented for antibacterial and antifungal properties, as are oregano, thyme, and cinnamon bark oils.

What precautions should be taken when using essential oils during pregnancy?

Answer: Many oils should be avoided in the first trimester; use only pregnancy-safe oils at reduced dilutions under professional guidance

Many essential oils should be avoided during pregnancy, especially in the first trimester. When used, pregnancy-safe oils (lavender, citrus) should be at lower dilutions (1%), and professional consultation is recommended.
