Quick Answer
Aromatherapy is the holistic therapeutic application of essential oils (concentrated plant extracts) to promote physical, emotional, and spiritual well-being. It works on two levels: pharmacological (the chemical effect of the oil entering the bloodstream) and psychological (the brain's emotional response to the scent).

Key Takeaways
- Insight 1: "Fragrance oils" are synthetic; "Essential oils" are natural. Know the difference.
- Insight 2: Lavender is the universal healer (sleep, skin, stress).
- Insight 3: Citrus oils can make skin sensitive to sunlight (photosensitivity).
- Insight 4: Diffusing is the safest way to start.
- Insight 5: Quality is paramount; look for GC/MS tested oils.
The Science of Smell
Essential oils are the "life blood" of the plant, containing its immune system and hormones. When you inhale an oil, microscopic molecules travel up the nose to the olfactory epithelium.
This signals the limbic system, the ancient part of the brain that manages emotion, memory, and instinct. This is why the smell of cookies might remind you of your grandmother, or why Peppermint immediately wakes you up.

Methods of Application
Aromatic: Use an ultrasonic diffuser to mist the oil into the air. Or, put a drop in your palm, rub hands together, and inhale (Palm Inhalation).
Topical: Dilute with carrier oil and apply to pulse points (wrists, neck) or soles of feet (pores are large there for quick absorption).
Household: Add Lemon oil to water and vinegar for a non-toxic cleaning spray.
Safety Guidelines
Warning: Never ingest essential oils unless under the care of a certified aromatherapist. They can burn the esophageal lining and tax the liver.
Always perform a patch test on your arm to check for allergies. Store oils in dark glass bottles away from heat to preserve their potency.
Frequently Asked Questions
Do essential oils expire?
Yes. Citrus oils oxidize quickly (1-2 years). Heavier oils like Patchouli and Sandalwood can last for many years and even improve with age.
What is "Therapeutic Grade"?
This is a marketing term, not a regulated standard. Look for "100% Pure Essential Oil" and check if the company shares their purity test results.
Can I use oils during pregnancy?
Some are safe (Lavender, Ginger), while others (Clary Sage, Rosemary) should be avoided as they can stimulate uterine contractions. Consult a doctor.
