How to Use Essential Oils Safely
- Always dilute before applying to skin. A general guide is 2–3 drops of essential oil per teaspoon (about 5 mL) of carrier oil such as jojoba, sweet almond, or fractionated coconut oil.
- Patch test first. Apply a small diluted amount to your inner arm and wait 24 hours to check for irritation.
- Do not ingest essential oils unless under the guidance of a qualified professional.
- Keep away from eyes, inner ears, and mucous membranes. If oil gets in your eye, flush with a carrier oil (not water).
- Phototoxicity: Citrus oils — especially bergamot, also lemon, grapefruit, and cold-pressed lime — can make skin more sensitive to sunlight. Avoid sun and tanning beds for at least 12 hours after applying them to exposed skin.
- Pregnancy & nursing: Check with your healthcare provider first. Use extra caution with clary sage, rosemary, peppermint, and basil.
- Babies & young children: Avoid peppermint and eucalyptus around the faces of infants and toddlers (the menthol/cineole can affect breathing). Use heavily reduced dilutions and consult a professional.
- Pets: Many essential oils are unsafe for cats, dogs, and birds. Diffuse only in well-ventilated spaces and give pets a way to leave the room.
- Store oils in dark glass, away from heat and direct light, with caps tightly closed.
