1️⃣ 🌬️ How Aromatherapy Works (The Short Version)
👃 Olfactory → Limbic: Scent molecules travel from your nose to brain regions that regulate mood, stress, and heart rate.
🧴 Topical (Diluted): Small molecules can pass through skin’s outer layer and may calm irritation or support barrier function.
🛡️ Bonus: Some oils show antimicrobial activity in lab settings, but use them mainly for comfort and ambience — not as medicine.
2️⃣ 🔒 Safety First (Please Read)
⚠️ Patch Test: 1 drop EO in 5 ml carrier; apply on inner forearm; wait 24 hours.
🌞 Phototoxic Oils: Citrus peel oils (lemon, grapefruit, bergamot) + sun = burns. Use bergamot FCF or avoid UV exposure for 12–24 hours.
🫁 Airway Safety: Keep sessions short (10–30 min), ventilate well, and be cautious if you have asthma or COPD.
👶 Special Groups: Infants, pregnancy, and pets require extra caution — or skip certain oils.
📦 Quality Control: Always check the botanical name, GC/MS report, and proper storage conditions.
3️⃣ 🧴 Choosing & Storing Essential Oils
✅ Check Labels: Botanical name + chemotype
✅ Confirm Purity: GC/MS report preferred
✅ Store Properly: Cool, dark place; tight caps; note open date
🗑️ Discard Old Oils: Oxidized oils raise irritation risk
4️⃣ 🌟 Top 20 Essential Oils — Mechanisms, Usage & Safety
Each oil includes: 🔬 Mechanism • 🧭 How to Use • ⚠️ Risks • 🔁 Comparison
1) 💜 Lavender (Lavandula angustifolia)
🔬 Linalool & linalyl acetate → calming via GABA pathways
🧭 Diffuse 3–5 drops (20–30 min); 1% topical (6 drops/30 ml)
⚠️ Rare sensitivity; avoid undiluted
🔁 Excellent for sleep/stress; gentler than mint or citrus oils
2) 🌱 Peppermint (Mentha × piperita)
🔬 Menthol triggers cooling TRPM8 receptors → clarity, focus
🧭 Steam 2–3 drops (5–10 min); diffuse 2–3 drops; 1% temples/abdomen
⚠️ May irritate airways; avoid near eyes; not for infants
🔁 Great for alertness; more stimulating than lavender
3) 🛡️ Tea Tree (Melaleuca alternifolia)
🔬 Terpinen-4-ol disrupts microbial membranes
🧭 1–2% topical for blemishes; diffuse 2–3 drops (15–20 min)
⚠️ May cause dermatitis; never ingest
🔁 Strong antimicrobial but higher irritation risk than lavender
