The 10 first aid essential oils I keep in every home kit are lavender, peppermint, lemon, tea tree, frankincense, sweet orange, eucalyptus, clove, helichrysum and lemongrass. Together they cover the everyday stuff: bug bites, bumps and bruises, tension headaches, queasy tummies, stuffy noses and stressful moments.
Below you'll find what each oil is traditionally used for, how much to dilute it, who should skip it, and a few simple blends to make ahead. They're also great starter oils if you're new to aromatherapy.
Essential oils support first aid; they don't replace it. They're a comfort for minor, everyday bumps and scrapes. For deep cuts, serious burns, allergic reactions, breathing trouble, signs of infection or anything that worries you, call your doctor or emergency services.
Build Your Essential Oil First Aid Kit
Tuck these into a small case alongside your regular first aid supplies:
- Your first aid oils (5 ml bottles or mini vials are plenty)
- A carrier oil like jojoba or fractionated coconut oil (see my list of carrier oils)
- Pre-made roller bottles (recipes below)
- A blank aromatherapy inhaler or two
- Pure aloe vera gel (learn more about aloe vera for skin)
- Bandages, gauze, tweezers, cling film, a thermometer and an elastic wrap
Short on time? My rollerball remedy kits come with everything you need to make ready-to-use rollers.
How to Use First Aid Oils Safely
For first aid, essential oils are used two ways: aromatically (an inhaler, a diffuser, or a tissue) and topically (diluted in a carrier oil, lotion or aloe gel). Always dilute before putting oils on skin.
| Who / What | Dilution | Per 10 ml Roller |
|---|---|---|
| Kids 2+, face, sensitive skin | 1% | 2 drops |
| Adults, everyday use | 2% to 3% | 4 to 6 drops |
| Adults, small area, short-term | Up to 5% (gentle oils only) | 10 drops |
- Some oils need lower limits. Clove stays at 0.5% and lemongrass at 0.7% or less. They're strong skin irritants.
- Never put oils into deep cuts, open wounds, blisters, eyes or ears. For scrapes, clean first with soap and water and apply blends around the area.
- Kids: skip peppermint for children under 6 and eucalyptus under 10.
- Patch test new blends on your inner arm, and stop if you notice redness or itching.
- Don't swallow essential oils, and store them out of reach of children.

The 10 Best First Aid Essential Oils
These are the oils I keep with my first aid supplies. You can fill mini vials and store them in a small case right in your kit.
1. Lavender Essential Oil
Lavandula angustifolia
Lavender is the Swiss Army knife of essential oils: gentle, calming and useful for skin, stress and sleep.

Max Dilution: Up to 5%
Safety: Choose true lavender (Lavandula angustifolia), not lavandin, for skin care.
Essential Oil Tip: Keep a lavender roll-on in your kit for bites and bumps. For sun-warmed skin, mix it into aloe gel. See lavender oil for sunburn.
2. Peppermint Essential Oil
Mentha x piperita
Peppermint is cooling and invigorating. It's my go-to for tension headaches, queasy moments and tired muscles.
Traditionally Used For: Tension headaches, nausea and motion sickness, digestive discomfort, muscle aches, stuffy noses, mental fatigue, hot days (cooling).

Minor Kitchen Burns
Lavender is a classic for burns, but timing matters. Cool water comes first and oils come later:
Minor Kitchen Burn? Do This First
- Cool it for 20 minutes. Cool (not ice-cold) water is the most helpful thing you can do. It draws heat out so the burn doesn't go deeper, and it still helps up to 3 hours later. You don't have to stand at a running tap: soak the burn in a bowl of cool tap water, adding fresh water as it warms, or hold a cool, wet cloth on it and re-wet the cloth often. (Water your plants with it afterward.) Take off rings or bracelets near the burn before it swells.
- Skip the ice. Ice is too cold for injured skin and can add a cold injury on top of the burn. It also numbs the area, so it feels better than it really is.
- Hold the oils for now. Oils, butter and balms hold heat in, the opposite of what you want. Once it's cooled, leave it alone or cover it loosely with cling film or a clean, non-fluffy dressing. Plain aloe vera gel is a gentle option if it feels hot.
- Save essential oils for later. Once the heat and sting have settled, usually the next day, and the skin is unbroken, a little lavender mixed into aloe gel (1 drop per teaspoon) is a gentle comfort. Never put oils on blisters or open skin.
Get medical care for burns larger than your palm, burns that blister or look white or charred, burns on the face, hands, feet, genitals or joints, chemical or electrical burns, burns on babies and young children, or any burn that shows signs of infection. Sources: NHS burns and scalds treatment and British Red Cross first aid for burns.
When to Skip the Oils and Get Help
Call your doctor, urgent care or emergency services for:
- Deep, gaping or dirty cuts, or bleeding that won't stop with pressure
- Burns larger than your palm, or burns on the face, hands, feet, genitals or joints
- Signs of infection: spreading redness, warmth, swelling, pus or fever
- Bites or stings with swelling of the face, lips or throat, hives or trouble breathing
- A head injury, a possible broken bone, or any injury in a baby or young child that worries you
