What Are Essential Oils?
Golden Rules of Essential Oil Safety
- 1.Always dilute essential oils in a carrier oil (jojoba, sweet almond, coconut) before applying to skin.
- 2.Patch test first — apply a diluted drop to your inner forearm and wait 24 hours before wider use.
- 3.Keep away from eyes, ears, and mucous membranes. If accidental contact occurs, flush with carrier oil, not water.
- 4.Not all oils are safe for children, pregnant women, or pets. Always verify safety before use around vulnerable populations.

Safety Essentials
Phototoxic Oils
Lemon, bergamot, lime, grapefruit, and bitter orange can cause severe burns or dark spots when skin is exposed to UV light after topical application. Avoid direct sunlight for 12–18 hours after use, or choose steam-distilled or FCF (furanocoumarin-free) versions.
Hot Oils
Clove, cinnamon, oregano, and thyme (ct. thymol) can cause a burning sensation on skin. Always use at very low dilutions (0.5% or less) and never apply undiluted.
Pregnancy & Nursing
Many oils are contraindicated during pregnancy, especially in the first trimester. Rosemary, clary sage, juniper berry, and peppermint should be avoided. Lavender, frankincense, and sweet orange are generally considered safe at low dilutions. Always consult your healthcare provider.
Pets
Cats lack a liver enzyme needed to metabolize many essential oils, making tea tree, eucalyptus, citrus oils, and many others potentially toxic to them. Dogs are more tolerant but still sensitive. Never apply essential oils directly to pets and ensure good ventilation when diffusing.
Children
Avoid peppermint and eucalyptus on children under 6 (the menthol and 1,8-cineole can cause breathing difficulties). Lavender, chamomile, and cedarwood are among the safest options for little ones. Always use child-appropriate dilutions.
