Every December a steel bottle turns up in half the homes I know. Mustard oil boiled down with ajwain, a few cloves of garlic, sometimes a pinch of methi, cooled and strained through muslin. Someone's dadi made it. It smells like winter. And the question lands in my WhatsApp around 11pm, almost always from a mother who doesn't want to offend anyone: is it safe to put on my baby?
Honest answer: I wouldn't use this recipe on a baby under one. Garlic is the ingredient I'd drop first. Raw garlic sitting on thin infant skin has caused chemical burns, and it contributes nothing to warmth in return. Mustard oil is the second problem. Brilliant cooking oil. Poor newborn massage oil, because the research that exists on it points the wrong way for the skin barrier. Ajwain-infused oil is the mildest of the three, and even that belongs on an older child, used sparingly. Not on a newborn.
At a glance
- The warm tingle this oil gives is not heat. It is mild irritation of the skin, and a baby can't tell you the difference.
- Garlic (lahsun) carries the highest risk: allicin and related compounds can burn thin skin, especially if the oil is left on under a cloth or in a warm room.
- Mustard oil (sarson) contains erucic acid and allyl isothiocyanate. Hospital research on newborn massage has found it can disturb the skin barrier rather than support it.
- Ajwain oil is thymol-rich. Lovely as a warm smell in the room, too strong for a newborn's skin at homemade concentrations.
- Keep the ritual. Change the oil. The massage is where the good comes from; the bottle is the part that worries me.
If you're weighing oils more broadly, treat this as the winter-recipe corner of our complete guide to baby massage and malish. Below, the four questions parents put to me about this bottle.
Is the ajwain, lahsun and sarson malish oil recipe safe for a baby?
As a whole recipe, no. The three don't carry equal risk, though, so let's take them apart.
A baby's skin is 20-30% thinner than an adult's. That single fact changes how every pungent ingredient behaves. What feels pleasantly hot on your forearm is a much bigger dose on a three-month-old's chest, and it gets in faster. Then add the things we all do without thinking: a shut, warm room, a swaddle over the top, oil pooling in the neck and thigh folds. You've concentrated it again.
| Ingredient | What it's believed to do | What happens on baby skin | My verdict |
|---|---|---|---|
| Lahsun (garlic) | "Gives garmi", keeps cold and cough away | Allicin and diallyl sulphides are potent skin irritants. Documented chemical burns in children from garlic left on skin, especially under a cover. | Leave it out. No exceptions under one year. |
| Sarson (mustard oil) | Warming, strengthening, "makes bones strong" | Erucic acid and allyl isothiocyanate give the sting. Studies on newborn massage have found mustard oil can impair barrier recovery rather than help it. | Not for newborns or eczema-prone skin. |
| Ajwain (carom) | Relieves gas, warms the tummy | Thymol-rich and truly aromatic. At homemade strength it's unpredictable — you can't know the concentration you've infused. | Mildest of the three. Still not for under-ones. |
| Methi (fenugreek) | Added for joints and "strength" | Largely inert in oil; mostly harmless, mostly pointless. | Neither here nor there. |
Look at what the table doesn't contain. Not one ingredient that raises a baby's body temperature through the skin. There isn't one. Warmth comes from the room, from cotton layers, from your hands.
Why is garlic the ingredient I'd drop first?
Because it does real, visible damage, and it does it quietly.
Garlic's sulphur compounds are the same ones that sting your eyes when you crush a clove on the sil-batta. On adult palms, rinsed off in a minute, nothing happens. On a baby, three things stack up. Skin that is thinner to begin with. Oil that holds those compounds against it instead of letting them evaporate. And a parent who leaves the massage on for an hour before the bath, which is exactly what most of us were taught to do. An hour is a very long contact time.
The pattern I've heard described more than once goes like this. A red patch appears on the chest or back. The family reads it as the oil working. By evening it has gone shiny, and by night it has blistered. Skin that reacts that way needs a doctor to look at it and say what it is — I can't tell you from here, and neither can anyone else who hasn't seen it. What I can say is that it isn't a rare story, and that the risk climbs with a stronger infusion and a longer, covered contact. Stop the oil and get it seen the same day.
Never do this combination: garlic-infused oil + a cloth, cling film, warm towel or tight swaddle over it + more than 20-30 minutes. Covering the skin traps the compounds against it and multiplies the effect. If a home remedy tells you to "cover it so the heat works", that is the instruction to walk away from.
Does it really keep a baby warm in winter?
This is the belief the whole recipe rests on, so let me be blunt. No. Not in the way people mean.
What these ingredients produce is a counter-irritant effect. They mildly irritate the nerve endings in the skin, and the brain reads that as heat. It's the same trick as a balm rubbed on an aching knee. The skin feels warm. Core body temperature doesn't move. In an adult that's a pleasant, harmless illusion. In a baby it is a sensation they cannot report, on skin that cannot take it, being read by everyone in the room as proof that it's working.
What does help a baby through a Nagpur or Delhi January is far less romantic. Shut the windows and the door before you start. Get the room to a comfortable 26-28°C. Warm the oil to body temperature by rubbing it between your palms. Never on the flame: a bottle heated on the stove holds hot spots you won't feel until it's on the baby. Massage 10-15 minutes. Dress in cotton layers straight after, cap on if the room is cool.
Commercial herbal formulations lean on the same warming logic, and it pays to know what those claims mean before you buy. We've unpacked what's inside lal tail and who it suits if you're comparing bottles.
My baby went red after the massage — is that normal?
A light, even flush that fades within 15-20 minutes is friction from your hands. That one is fine. It isn't what I want you watching for.
Watch instead for redness that is still sitting there an hour later. Redness in a patch, rather than everywhere your hands went. Skin that feels hot or tight under your fingers. Raised welts. Tiny blisters. A baby who cries when you touch that one spot and nowhere else. Stop the oil that day. Wash the area gently with lukewarm water and a mild, tear-free baby wash to lift the oil film off. Plain water won't shift oil, and whatever stays behind keeps the irritant in contact. Then moisturise and leave the skin alone for a few days.
One thing parents miss: rancidity is an irritant in its own right, and an oil that has stood in a reused bottle beside the stove for six weeks is a candidate. Homemade infusions have no preservative system and no antioxidant. If it smells sharp, waxy or plainly "off" against the day you made it, that isn't only unpleasant. It is more likely to sting.
Can I keep the tradition in a safer way?
Yes, and I'd far rather you did than give up malish altogether. The value sits in the massage itself: the skin contact, the rhythm, the 15 quiet minutes when nobody is asking anything of either of you. The bowl is the part I'd change. Everything else can stay exactly as it is.
Keep the vessel, the timing, the person who does it, the whole feeling of it. Swap what goes in the bowl for a plain, well-filtered carrier oil that suits your baby's skin. If you're weighing a ghani-pressed oil from the local mill against a manufactured one, we've compared cold-pressed and branded baby massage oils honestly, including where each one wins.
- Patch test first, always. A 10-paisa-sized dab behind the ear or on the inner forearm. Leave 24 hours. Check twice. Do this even for an oil your family has used for generations.
- Use 5-10 ml. Roughly a teaspoon to two for a whole baby. More oil doesn't buy more benefit. It buys a slippery baby and a longer wash.
- Warm it between your palms, never on the stove. Test on your inner wrist.
- Nothing in the nose, ears, eyes or on the cord stump. Non-negotiable, whatever is in the oil.
- Set the order deliberately. Most Indian homes do oil, then bath. If you're unsure which suits your baby, here's how to decide between malish before or after the bath.
- Wash the oil off within a few hours. Don't let a scented film sit overnight in the neck, the groin, behind the knees.
- Make small batches. Two weeks' worth, in a clean glass bottle kept away from the stove and out of the sun. Discard it if the smell changes.
- Moisturise after the bath, on skin that is still slightly damp. This is the step that holds water in through a dry winter. Oil alone doesn't.
If the tradition matters to the family and you want a compromise, here's mine: keep ajwain in the room, not on the baby. A small bowl of it warmed dry, kept at a safe distance, gives the same familiar winter smell. Nobody has to argue about the massage oil.
When to see a doctor
Take your baby to a paediatrician — the same day, not next week — if after any oil you see blistering, weeping or peeling skin, redness that spreads beyond where you applied it, hives, swelling of the face or lips, or any change in breathing, wheezing or coughing after a strongly scented oil. Also see a doctor if a red patch hasn't settled within 48 hours of stopping the oil, if the skin looks infected (yellow crust, warmth, a fever), or if your baby is preterm, under a month old, or has diagnosed eczema. In those cases, ask before you start any oil, not after. And don't put a second remedy on top of irritated skin to "cool it down". Let a doctor see it as it is.
For dry, winter-worn skin after a gentle massage and bath, I'd finish with a barrier-supporting balm. Our Hydra Healing Moisturizing Balm is made for exactly that job, in our own GMP-certified facility.
In summary
- Skip garlic entirely in any baby massage oil — it can burn thin infant skin, especially under a cloth or swaddle.
- Mustard oil's warm sting is skin irritation, not body heat, and it isn't a good fit for newborn or eczema-prone skin.
- Ajwain is the mildest of the three, but a homemade infusion has an unknown strength — keep it off under-ones.
- Warm the room to 26-28°C and warm the oil between your palms; that, plus cotton layers, is what actually keeps a baby warm.
- Keep the ritual and change the oil: patch test 24 hours, use 5-10 ml, wash it off within a few hours, and moisturise on damp skin.
Frequently asked questions
Can I use mustard oil for my newborn's malish in winter?
I'd avoid it for a newborn. Mustard oil contains erucic acid and allyl isothiocyanate, the compounds behind its pungency and sting. Hospital research on newborn massage has found mustard oil can disturb the skin barrier rather than support it. The warmth you feel is a counter-irritant effect, not real heat. A plain, mild carrier oil does the massage job without the sting.
Is garlic-infused oil safe for baby massage?
No. Garlic's sulphur compounds, including allicin, are potent skin irritants, and chemical burns from garlic left on children's skin are documented. The risk rises with longer contact and anything that covers the area — a cloth, swaddle or warm towel. Garlic also does nothing to raise a baby's body temperature. It's the first ingredient I'd remove from any homemade winter malish oil.
At what age can I use ajwain oil on my child?
Ajwain is the mildest of the three but still not for babies under one. Thymol, its main active, is strong on thin skin, and a home infusion has no measurable concentration — you can't know how strong your batch is. For an older child, use a small amount, patch test 24 hours behind the ear first, and stop at any redness that outlasts the massage.
How do I actually keep my baby warm during a winter massage?
Room temperature and layers, not ingredients. Shut windows and doors first, get the room to a comfortable 26-28°C, warm the oil to body temperature between your palms rather than on a flame, and keep the massage to 10-15 minutes. Dress the baby in cotton layers immediately after, with a cap if the room is cool. No oil warms a baby from the outside in.
My baby's skin turned red after the traditional malish oil. What should I do?
An even flush that fades within 15-20 minutes is normal friction. A patch that stays red past an hour, feels hot or tight, or shows welts or blisters is irritation. Stop that oil. Wash the area with lukewarm water and a mild baby wash — plain water won't lift oil — then moisturise and leave the skin alone. See a paediatrician if it blisters, weeps or spreads.
How long can I store homemade ajwain-garlic massage oil?
Homemade infusions have no preservative or antioxidant system, so they go rancid — and rancid oil stings more. If you make one at all, make a two-week batch, store it in a clean glass bottle away from the stove and sunlight, and throw it out the moment the smell turns sharp, waxy or different from the day you made it. Never top up an old bottle with a fresh batch.
