Pudina ka Phool, Ajwain ka Phool and Kapoor: Uses and Dangers
Pudina ka phool isn’t a flower at all. It’s menthol crystals (the cooling chemical of mint), sold in little jars beside ajwain ka phool (thymol crystals from ajwain) and kapoor (camphor). Mix the three and they melt into a sharp, clear liquid, the base of amritdhara-style drops. For adults they have real outside-the-body uses. For children they’re poisons: camphor especially can cause fits within minutes to hours from a small amount, and menthol near a baby’s nose can make breathing stop. Here’s what each crystal is, how adults use them safely, and how to store them so a child never finds them.
Go to hospital now and bring the jar or bottle; don’t wait for symptoms, don’t make the child vomit, and don’t give milk or oil “to settle it”. Signs of poisoning include a burning mouth, drooling, vomiting, unusual sleepiness or agitation, fast breathing, twitching or a fit. Camphor fits can start within 5 to 90 minutes; in an adult who swallowed a mouthful, the same rule applies.
Quick facts

What exactly is pudina ka phool, and what are the other two crystals?
Same family. All three are aromatic chemicals that come out of plant oils as solid crystals when cooled.
- Menthol (pudina ka phool): crystallises from the oil of a mint species, mostly cornmint; it triggers the skin’s cold sensors, so it feels icy without changing the temperature. Pudina ka phool in English is simply “menthol crystals”.
- Thymol (ajwain ka phool): the main aroma chemical of ajwain and thyme, crystallised out; it’s sharp, burning and strongly antiseptic. It’s used in some mouthwashes in tiny amounts.
- Camphor (kapoor): traditionally from the camphor tree, today mostly made synthetically. Bhimseni kapoor is the natural, edible-grade kind used in tiny amounts in some sweets and in worship; plain kapoor tablets for puja or mothballs are not food.
Our full camphor guide, kapoor uses and the poisoning risk for kids, goes deeper on the third crystal; this article is about all three together, and the mixtures made from them.
What do people say these crystals do?
The common opinion, often heard at pansaris: a “teen phool” mix rubbed on the forehead takes away headache, a drop on sugar settles stomach ache and gas, a few drops in hot water clear a blocked nose, and the liquid on a tooth stops pain. Pudina ka phool is also said to help with acne, itching and hair fall.
Unani and Ayurvedic practice use all three as strong “hot” aromatics. Sat pudina, sat ajwain and kafoor appear in balms, inhalations, digestive drops and tooth powders. Equal parts of the three melt into a liquid, and that liquid, sometimes with other oils, is the old base of amritdhara-type remedies sold for gas, nausea, headache and colds.
Here’s a true and surprising fact: the crystals melt together at room temperature even though each one alone is solid; chemists call that a eutectic mixture. It’s why the jar of “teen phool” liquid never sets.
Our honest take: which uses are fair for adults?
Well supported: menthol gives a real cooling, mildly numbing feeling on skin; that’s why it’s in balms, pain gels and cough drops. It doesn’t open the nose, but it makes the airflow feel easier, and for a stuffy adult that’s comfort. Thymol is a genuine antiseptic in small, controlled amounts, which is why it shows up in some mouthwashes and dental products made under factory conditions, not in a home jar. Camphor on the skin warms and mildly numbs.
Plausible but unproven: a menthol rub on the temples easing tension headache for some people. A menthol gel on the forehead has some support for this; a home mix is less predictable.
False or unsafe: anything that puts these crystals in a child’s mouth, nose or chest rub; swallowing home-made mixtures. Neat liquid on skin, gums or teeth (it can burn); acne or hair-fall claims.
Shop products made to be taken by mouth, such as amritdhara-type drops, carry their own directions. Those are adults-only medicines: the pack sets the amount, and they’re not for pregnancy, breastfeeding or children. Depends: diluted, outside the body, for adults, yes. Anything else, no.
How can adults use them safely on skin or in steam?
Dilute. Always. Dilution is everything. Neat crystals and neat “teen phool” liquid can blister skin and burn mucous membranes.
- Patch test first: make the oil below, dab a pea-sized amount on your inner forearm and wait 48 hours; redness, burning or a rash means don’t use it.
- A gentle menthol oil for aching muscles: warm 50 ml of coconut or sesame oil to about 40 °C (warm, not hot) and stir in about a quarter of a level teaspoon of menthol crystals (roughly 0.5 g, giving about 1%) until dissolved.
- Rub a fingertip’s worth into the sore area. Wash your hands straight after, before touching your eyes, your contact lenses or a child.
- Don’t use it on broken, sunburnt or freshly shaved skin, and never cover it with a hot water bottle or a tight bandage; heat on top of these chemicals can burn.
- For a blocked nose (adults only): plain steam from a bowl of hot water, about 1 litre at 60 to 70 °C, works well on its own. If you add anything, one or two small menthol crystals is plenty. Keep your face about 30 cm away, eyes closed, for 5 to 10 minutes.
- Do steam with the bowl on a table, never on your lap, and with no children in the room. Our ajwain steam guide covers scald safety.
- Label the oil bottle clearly with what it is and the date you made it, and store it with the crystals, locked, using it up within about 3 months.
Why are these crystals so dangerous for children?
- Camphor causes fits. A small amount swallowed, even a lick of strong camphor oil, has caused seizures in toddlers; it’s absorbed fast, and fits can start before parents realise anything is wrong.
- Menthol and babies’ breathing. Menthol or camphor near a baby’s nose can trigger a reflex that makes the airway clamp shut (laryngospasm) or slow breathing. That’s why “Vicks on the chest or under the nose” is a no for babies and young children.
- Thymol burns. Swallowed or licked, it can burn the mouth and throat and cause vomiting.
- They look like sweets or ice. Clear crystals and white tablets are exactly what toddlers put in their mouths, and a jar left open on a bedside table after a late-night headache rub is how many of these accidents begin.
- Skin absorbs them. A baby’s thin skin takes in more for its size, so rubs on a baby’s chest, feet or soft spot aren’t safe either.
Arq ajeeb, a liquid made from the same family of chemicals, carries the same warning; see arq ajeeb and the baby warning.
Myth: a little on the soft spot or chest settles a baby’s cold
Please don’t. It doesn’t help. For a stuffy baby, the house method is home saline: half a level teaspoon of salt in 250 ml of boiled, cooled water, a few drops in each nostril, then gentle suction. Hold your baby upright while awake; for sleep, the rule doesn’t change: flat on their back in a bare cot, never propped.
How should you store pudina ka phool, ajwain ka phool and kapoor?
- Keep them in their original, labelled, tightly closed jars. Never decant them into sweet tins, film canisters or unlabelled bottles, because a child, a guest or a tired adult at night will assume a familiar tin holds something familiar.
- Store them in a locked cupboard, high up, away from food and children’s medicines, and put them back the moment you finish rather than “in a minute”.
- Keep puja camphor and mothballs out of children’s reach too, and don’t leave them in drawers with clothes children can open.
- Close the lid after every use; the crystals evaporate slowly and the smell spreads.
- When visitors with toddlers come, check bedside tables and handbags for balms and crystal jars.
Buy from a shop that sells a sealed, labelled jar with the chemical name on it; crystals that are sticky, discoloured or smell “off” are old or mixed. For more plain-spoken household remedy guides, see Desi Remedies.
Pudina ka phool and the other crystals: common questions
What is pudina ka phool in English?
Pudina ka phool is menthol crystals, the cooling chemical crystallised out of mint oil; despite the name, it isn’t a mint flower. “phool” is simply the traditional shop name for these crystals.
Pudina ka phool kis kaam aata hai?
For adults, it’s used diluted in oils, balms and steam for a cooling feel on aching muscles and a stuffy nose; it’s also an ingredient in many shop products. It isn’t for children, and it shouldn’t be swallowed at home.
What are pudina ka phool benefits?
The real benefit is a cooling, mildly numbing sensation on skin and an easier-feeling breath for adults with a blocked nose; claims for acne, hair fall and stomach problems from home use aren’t backed by good evidence.
Pudina ka phool kaisa hota hai?
It looks like clear, colourless needles or small chunks, a bit like crushed ice or rock salt, with a powerful icy mint smell. Ajwain ka phool looks similar but smells of ajwain, and kapoor is white and waxy.
Is it safe to eat pudina ka phool?
No, not as crystals. Food products use food-grade menthol in tiny traces, already measured in. Swallowing crystals or a home mix can burn the mouth and stomach and cause poisoning; mouth products should only be taken as the label says, by adults.
What happens when you mix ajwain ka phool, pudina ka phool and kapoor?
They melt into a clear liquid at room temperature, a eutectic mixture; this is the base of amritdhara-style drops. The liquid is strong: never use it neat on skin and keep it away from children entirely.
Can I use pudina ka phool on my baby for a cold?
No. Menthol and camphor near a baby’s nose or on the chest can trigger breathing problems and fits. Use home saline drops (half a level teaspoon of salt in 250 ml boiled, cooled water) and see a doctor for any breathing difficulty.
My child licked kapoor. What should I do?
Go to hospital now and bring the packet, even if your child seems fine, because camphor can cause fits within minutes to hours; don’t make them vomit and don’t give anything to drink first.
Is pudina ka phool good for headache?
A diluted menthol rub on the temples gives some adults relief from tension headache. Keep it well away from the eyes and wash your hands after; a sudden severe headache, or one with fever and a stiff neck, needs a doctor.
Can I use these crystals in pregnancy?
Avoid camphor and anything taken by mouth. A small amount of diluted menthol on the skin is generally considered low risk, but check with your doctor or midwife first, and stop if it irritates.
Is ajwain ka phool the same as ajwain?
No. Ajwain ka phool is thymol, the concentrated aroma chemical. Ajwain seeds in food are safe in normal kitchen amounts; the crystal is far stronger and isn’t a food.
Pudina ka phool for hair or skin?
There’s no good evidence it helps hair growth or acne; a menthol shampoo feels tingly, but neat crystals or strong oils can burn the scalp and skin. Patch test any homemade oil for 48 hours.
