Effective Essential Oil Dosage: Guidelines by Method

No Universal Dose—Context Is Everything

Effective dosage depends on: specific oil, application method, user age/health, desired outcome, and sensitivity. Always prioritize safety.

General Guidelines

Inhalation (Aromatherapy)

• Diffuser: 3–10 drops per 100ml water; run 30–60 min on/off.
• Steam inhalation: 1–3 drops in bowl of hot water; tent with towel, 5–10 min.
• Personal inhaler: 5–15 drops on cotton wick.

Topical Application

• Adults: 1–5% dilution (6–30 drops per 1 oz / 30 ml carrier oil).
• Children (2+), elderly, sensitive skin: 0.5–2% (3–12 drops/oz).
• Infants: Avoid or 0.1–0.5% only under professional guidance.
• Carriers: Jojoba, fractionated coconut, sweet almond, olive oil.

Internal Use – Extreme Caution

• Only under qualified clinical aromatherapist/physician supervision.
• Typical: 1–2 drops in capsule, honey, or dispersant—not in water (oil floats, irritates mucosa).
• GRAS (Generally Recognized as Safe) oils only—and even then, medicinal use differs from flavoring.

Critical Safety Rules

1. Patch test before widespread use.
2. Avoid eyes, ears, mucous membranes.
3. Photosensitizing oils (citrus) → no UV exposure 12–18 hrs post-application.
4. Contraindications: Pregnancy, epilepsy, hypertension, medications, pets (especially cats).
5. Quality: Use only pure, GC/MS-tested oils from reputable suppliers.

When in Doubt

Consult a certified clinical aromatherapist (NAHA, AIA) or integrative healthcare provider.
