Uses of Mustard Oil: How Indian Homes Use It

In an Indian home, mustard oil (sarson ka tel) earns its keep two ways: in the kadhai and on the body. In cooking it is the backbone of everyday tadka, the smoky base of a Bengali fish curry or aloo dum, the oil that gives achaar its bite and long life, and a dependable choice for deep-frying thanks to its high smoke point (around 250 C). Off the stove, generations have reached for it to oil hair, for body and baby malish, on the skin, and in small home remedies - a turmeric-and-mustard-oil rub for gums, a warm drop for stubborn ear wax, a diya lit for pooja. It is prized because true kachi ghani (cold-pressed) mustard oil keeps the seed's colour, pungent aroma and natural compounds instead of being stripped by refining. And the 'is it banned?' worry you may have read online is really about the West: in India it stays a permitted, FSSAI-regulated everyday oil, while the US restricts it as a food oil over its natural erucic acid.

What is mustard oil, and what does it look and smell like?

Mustard oil is the oil pressed from mustard seeds (sarson) - the same little seeds that grow on the bright-yellow-flowered fields you see across north India in winter. Good kachi ghani oil is a clear, golden-yellow liquid; hold a spoonful to the light and it should pour as a bright yellow drop, not cloudy or pale and watery. Its smell is its signature: sharp, pungent, almost peppery, the aroma that hits the back of your nose when the oil is heated for tadka. That pungency comes from natural compounds in the seed and is a sign the oil has not been over-refined into blandness.

The seed itself is tiny - roughly one to two millimetres across, round, and ranging in colour from yellow and pale brown to the near-black of some varieties. The mustard crop is a rabi (winter) crop; sown after the monsoon, it usually takes a few months to go from seed to a field ready for harvest, depending on variety and region. Across India the oil goes by many names: sarson ka tel in Hindi, sarsav or rai nu tel in Gujarati, kadugu ennai in Tamil, and shorsher tel in Bengali - a reminder of how deeply it is woven into regional kitchens.

What is mustard oil used for in Indian cooking?

In the kitchen, mustard oil is a high-heat, big-flavour oil - which is exactly why it anchors so many regional cuisines. Its high smoke point (around 250 C) means it holds up to frying, tempering and searing without breaking down quickly, and its pungency mellows into a nutty, rounded depth once heated. A common technique is to first heat the oil until it just begins to smoke ('pakana'), then lower the flame before adding your tadka - this softens the raw sharpness that some people find strong.

• Tadka and bhuna: the base for tempering whole spices, onions and ginger-garlic in everyday sabzi, dal and curries.
• Achaar (pickles): its pungency and preserving character make it the traditional oil for mango, lime and chilli pickles that keep for months.
• Deep-frying: pakoras, kachoris and fish - the high smoke point suits high-heat frying.
• Regional staples: Bengali and Bihari fish and vegetable dishes, Kashmiri and eastern UP cooking, and Punjabi sarson da saag all lean on it.
• Marinades: rubbed onto fish or paneer before frying or grilling for flavour and colour.

Mustard oil uses for the body: hair, skin, massage and small remedies

Beyond the stove, mustard oil has a long place in Indian body-care tradition. Many families use it warm for hair oiling and for full-body and baby massage (malish), on the skin in winter, and in a handful of household remedies. It is important to be clear here: the notes below describe traditional and everyday uses, not proven medical treatments. This is general information, not medical advice - for any skin, ear, dental or health concern, please consult a qualified doctor, dentist or dietitian.

• Hair: warmed and massaged into the scalp before a wash - a classic weekly champi. See our full guide on mustard oil for hair.
• Skin and face: some cooks and grandmothers apply a little in winter for dryness; patch-test first, as its pungency can irritate sensitive skin. See mustard oil for skin and face.
• Massage and pain: warmed oil is traditionally used for body malish and to comfort everyday aches and stiffness. See mustard oil for massage and pain.
• Teeth and gums with turmeric: a paste of mustard oil with a pinch of turmeric (and sometimes salt) is a traditional gum-and-teeth rub - it is a folk practice, not a substitute for brushing or a dentist's care.
• Ear wax: a warm drop of mustard oil is a common home method to soften ear wax. Do not use it if you have ear pain, discharge or a possibly perforated eardrum, and see a doctor rather than digging in the ear.

One caution worth repeating for new parents: baby malish with mustard oil is a widespread tradition, but skin guidance is mixed - some advice cautions against using mustard oil on a newborn's delicate skin. Before oiling an infant, check with your pediatrician and do a small patch test first.

Mustard oil in pooja and Indian tradition

Mustard oil is also part of ritual and household tradition. It is one of the common oils used to light diyas and lamps during pooja and festivals like Diwali, and it appears in various regional customs and observances. For families, that dual role - food and rite - is part of why a bottle of good sarson ka tel is always in the kitchen. Read more in mustard oil in pooja and tradition.

How to check mustard oil quality before you buy

The single biggest quality marker is how the oil is made. Kachi ghani (cold-pressed / ghani) mustard oil is crushed slowly at low temperature with no added heat, no solvents and no bleaching or deodorising, so it keeps its deep yellow colour, strong aroma and the seed's natural compounds. Refined mustard oil is heat- or solvent-extracted and then degummed, bleached and deodorised - lighter in colour and milder in smell, but stripped of much of that character. When comparing brands, don't just chase the lowest price; look for how the oil is pressed, whether it is organic, and that it carries a valid FSSAI mark, which in India is a legal requirement for edible oil.

• Look: a clear, bright golden-yellow drop; genuine kachi ghani oil is richly coloured, not pale and watery.
• Smell: a strong, sharp, pungent aroma. Very faint smell usually means heavy refining or dilution.
• Label: look for 'kachi ghani' or 'cold-pressed', an FSSAI licence mark, a pressing/best-before date, and 'organic' if that matters to you.
• Freeze test at home: pure mustard oil stays largely liquid and clear when chilled; if it separates into white solidified layers in the fridge, it may be blended with another oil.
• Sensory smoke: when heated it should give that familiar pungent kick, then mellow - not stay flat and odourless.

On brands: rather than chase a name, buy on how the oil is made and how honestly it is labelled. Look for cold-pressed, single-origin, well-dated oil in a sealed can or bottle from a seller you trust. Organikaly's mustard oil is kachi ghani (cold-pressed) yellow mustard oil, made the slow way to keep its colour, aroma and natural character - you can buy it online from our store.

Can you carry mustard oil on a flight?

Mustard oil is treated like any liquid, so the answer depends on where you pack it. In checked baggage, edible cooking oil is generally allowed - seal the cap tightly, bag it, and cushion it so it doesn't leak or break in transit. In your cabin / carry-on bag, the standard security limit on liquids applies (containers of up to 100 ml, within a small clear pouch), so a normal oil bottle or can won't clear hand-baggage screening. Rules vary by airline and country, so for anything larger or for international travel, check your specific airline's baggage policy before you fly.

Should you use mustard oil - and is it really banned?

In India, the short answer is yes: mustard oil is a permitted, everyday edible oil regulated by the FSSAI and a culinary staple across the country. The confusion comes from abroad. Traditional mustard oil is naturally high in erucic acid (roughly 20-40% or more of its fat), and because of this the U.S. FDA does not authorise mustard oil as a cooking oil for domestic sale - imported mustard oil in the US must be labelled 'For external use only'. The EU and Codex also set limits on erucic acid in edible oils, and low-erucic ('canola-type') mustard varieties exist. So the 'ban' you may have read about is a US and some-Western regulatory position, not an Indian one.

On composition, the facts are steady: mustard oil is naturally high in monounsaturated fat (MUFA), contains omega-3 ALA and omega-6 linoleic acid, is low in saturated fat, and - like all plant oils - contains no cholesterol. As with any oil, it is calorie-dense (roughly 884 kcal and about 100 g of fat per 100 g, per USDA FoodData Central). For how any of this fits your own diet or a specific health condition, this is general information and not medical advice - talk to a qualified doctor or registered dietitian, and for infants consult a pediatrician.

Buy on how the oil is made, not on how loud the label shouts: a bright yellow drop and a real pungent kick tell you more than any claim.
