Mustard Oil: Benefits, Types, Uses & Complete Guide (2026)

Part 1: Introduction and Basics

Indian kitchens have relied on mustard oil for generations. From Punjab’s wavy yellow sand to the frying of fish in West Bengal, mustard oil is not only used for frying food, but it is also an integral part of cooking, traditional medicine, and natural remedy passed down from one generation to another. Although mustard oil can be used for cooking, as a warm oil used in massage therapy, and as a way to relieve cold symptoms, millions of households around the world rely on mustard oil daily.

This guide provides you with everything you will need to know about mustard oil — including its type, its benefits, its cost, and how to test for purity.

What is Mustard Oil?

Mustard oil is obtained from Brassica seeds. Mustard oil is not a single substance, but two different products having different composition and uses. One is Pressed oil or Culinary oil and another product is Essential oil or the Volatile oil. The Culinary oil contains Erucic acid, Oleic acid, Linoleic acid and Linolenic acid. About 81% fatty acids in Pressed oil are mono and Polyunsaturated fats and about 19% saturated fats. The Essential oil contains mainly about 90% of Allyl isothiocyanate. The Pressed oil is mainly used for cooking purpose, whereas the Essential oil is used as favouring agent.

In A Market Filled with Refined Oils, Mustard Oil is The Only One You Need for Good Health

Mustard oil has become an important part of Indian households for generations. It is known for its strong aroma, natural extraction process, purity and multiple uses. These qualities make mustard oil stand out among others. Mustard oil is used for cooking and it is also useful for other health benefits. That is why, many people use mustard oil over other oils because of its unique benefits.

What Makes Mustard Oil Unique?

Mustard oil is naturally extracted from mustard seeds. Which are yellow in colour and have a strong and unique smell. This yellow mustard oil is made in a very traditional way. That is why most people like it. Mustard oil has a lot of things like nutrients, vitamin A, vitamin C, and vitamin B. It also has a little bit of vitamin E. All these nutrients and vitamins are good for our health.

Nutritional Composition

Nutritional Value of Mustard Oil (Per 100ml Approx.)

The oil has a variety of nutrients in one tablespoon (or about 15ml) — including energy (900 calories), total fat (100g), saturated fat (12g), monounsaturated fats (60g), polyunsaturated fats (21g), omega 3 fatty acids (alpha linolenic acid, 6g) and omega 6 fatty acids (linoleic acid, 15g). Vitamin E is also abundant in mustard oil at 20mg, while mustard oil does not contain cholesterol.

Note: Values are approximate and may vary from brand to brand and extraction method.

Types of Mustard Oil

There are different types of mustard oil available in the market, depending on the extraction method. The most popular types are cold-pressed mustard oil and kachi ghani mustard oil, which are known for their strong flavour, aroma and rich nutrients which are preserved only by these processes.

Cold Pressed

Cold-pressed mustard oil is made by grinding dried mustard seeds. They do this without any heat or chemicals. Because of this reason it is said to be in purity form and the pureness without a mix of chemicals makes the oil unique in taste.

Kachi Ghani

Kachi ghani mustard oil is produced by using a wooden or steel press and crushing the mustard seeds at low temperatures. This is why it contains the purity and nutrients as we didn’t use any external heat or chemicals.

How to Choose Best Mustard Oil?

Check the label:

· Look for “Kachi Ghani” or “Cold Pressed” to get maximum nutrients.
· Avoid oils with added colours or preservatives.
· Check the packaging date and expiry date.

Check the colour

· Pure mustard oil is reddish-brown to deep amber.
· If it looks too light or pale, it may be refined or mixed.

Check the smell:

· Pure oil has a strong, sharp, pungent aroma.
· If it smells like chemicals or has no smell, be careful.

Check the price:

· If the price is too low, the oil may be adulterated.
· Good quality mustard oil costs between ₹150 to ₹250 per litre.

Check for FSSAI or AGMARK certification:

· In India, look for FSSAI approval on the bottle or tin.
· Certified oils are tested for purity and safety.

Yellow vs Dark Mustard Oil

Yellow mustard oil is obtained from yellow seeds and is milder in flavor and usually thicker and more viscous. Dark mustard oil is obtained from brown (or black) seeds and is much stronger-flavored and thinner.

Is “Yellow” mustard oil better than “Black”?
Yellow oil is often preferred by people who find the traditional black seed oil too “eye-watering”.

Mustard Oil in Various Languages

This oil is widely used in India by people from various regions. For example, people who speak Telugu call mustard oil Avalu Nune, and people who speak Tamil call it Kadugu Ennai. Likewise, people speaking Hindi or Urdu language call it Sarson ka Tel. These regional names show how widely mustard oil is used across the country.

Part 2: Price and Market Information

Price of Mustard Oil

Its price depends on factors like brand, extraction method and packaging quantity. Cold-pressed and Kachi Ghani mustard oil are generally high-priced due to their traditional methods of extraction. However, many consumers wouldn’t mind the price after knowing about its benefits. Popular brands like Fortune mustard oil have made these varieties easily available in the market at reasonable prices.

Mustard Oil Price Watch: What You Will Pay Right Now (Feb 2026)?

If you are going to replenish your pantry this week, here is what mustard oil costs around various retailers. Price fluctuations will vary somewhat, but the average cost of conventional brands appears to be about ₹170–₹190.

Quick Brand Comparison

· Best Value (Everyday Use): While you can find fortune and pansari both priced at an identical ₹168 per liter, Swiggy Instamart offers you the opportunity to procure a ₹338 two-liter pack, thereby saving you about a rupee or two.

· The Organic Difference: If you’re on the lookout for cold-pressed/organic alternatives such as foreka or nuova, expect a little higher price; however, you can get them for about ₹250-270 per litre.

· The Global Gap: The escalation in price outside India is unbelievable. In Germany Spice Bazar, one litre of cooking oil costs around ₹680 (Approx €7.49).

Official Government Averages:

The department of consumer affairs recently updated their average tracking mid-February. The national retail average is ₹186.97 for cooking oil (for that same time period). If you are paying greater than ₹200 for a conventional (Regular) brand of cooking oil, you should shop elsewhere.

Price Categories by Budget

I have separated traditional grocery stores into three different groups based on their budget:

· Budget Options (₹150 – ₹180): Dalda is the best option out of this range and can be used for heavy deep frying purposes.

· Mid-Range Options (₹168 – 250): Most of the people in India will shop within this price range. Brands like Fortune, Tata Simply Better, and Dabur can easily be found in this category.

· Premium Options: Organic India and Bliss of Earth are examples that fall into this category. Their price ranges from ₹250 – ₹500. You are paying for the certification process used to verify that each of these products has been produced using traditional methods of extraction and processing.

How to Store Mustard Oil?

Thanks to its natural antioxidants , mustard oil will keep fresh longer. However, it still needs to be stored properly:

– Keep the mustard oil in a dry, cool area away from the sun’s rays.
– Make sure the cap/lid is always tightly closed when you are done using it.
– Do not store the mustard oil near the stove or other sources of heat.
– Never mix water or wet spoons into the bottle of mustard oil.
– If stored correctly, pure mustard oil has a shelf life of approximately 12 to 18 months.

There are five important signs that your mustard oil has spoiled:

– A stale or off odor.
– A darker color than what is considered normal.
– A thickness to the mustard oil, along with an accumulation of sediment in the bottom of the bottle.
– A bitter or off-tasting mustard oil.
– A noticeable lack of freshness.

Part 3: Uses and Applications

Culinary Uses

Is it ok to consume the oil uncooked?
“Kachi Ghani” (cold-pressed) oil is often eaten uncooked and used in things like pickles or as a topping for other foods, such as Zaza and Roti.

Why is mustard oil so important in making traditional pickles?
Not because of the taste, but the oil has natural antifungal properties that helps keep pickles for a long time without refrigeration.

Is mustard oil a good choice for seasoning (as in creating a non-stick surface on) a pan?
Definitely! Applying a small amount of mustard oil beforehand can provide a natural non-stick surface to the pan.

Does the addition of lemon to oil eliminate the scent of canola?
Yes. Home cooks who add 1 or 2 drops of lemon juice to the oil while cooking say it reduces the “sharp” smell of canola.

Is Mustard Oil Only for Winter Cooking?
In Ayurveda, this kind of oil is known as warm oil. Therefore, many believe it will help in circulation and thus is more commonly used during cold seasons. However, these types of oils can also be used year-round in different parts of the world where it is safe.

Why do South Indian folks not cook with mustard oil?
It is because of regional and cultural preferences. While the oil is a staple in the regions of Bengal, Bihar, and Odisha, many South Indian cooks prefer to use either coconut or sesame seed oil when cooking.

Smoke Point and Cooking Guide

It can withstand high heat without breaking down or producing harmful substances due to its high smoke point (about 250 °C).

Why Is the Smoke Point Important?

– Oils that have low smoke points will burn easily and create smoke.
– When cooking an oil burns it will destroy its nutrients and create harmful by-products.
– Oils with high smoke points are better for frying or cooking over high heat.

How mustard oil compares to other oils:

Oil Type Smoke Point:

Mustard Oil 250°C
Coconut Oil 177°C
Olive Oil (Extra Virgin) 160°C
Sunflower Oil 225°C
Rice Bran Oil 230°C

Tip for first-time users:
If you can’t stand the smell of cold-pressed mustard oil, partially heat the oil (to its smoking point) and allow it to cool before using. This way you will reduce the amount of pungent aroma while still retaining the flavor of the oil.

Mustard Oil for Personal Care

The oil is really good for a lot of things. Mustard oil for hair is used to massage our scalp. It helps stop our hair fall and makes it less frizzy and makes the roots of hair strong. In other ways, mustard oil is used for body massage, which helps the body relax and feel lighter.

Will applying it to my hair make me go blind?
No, while this oil has a pungent odor, and is irritating to the eyes if used excessively, it has long been used in the traditional practice of treating dry scalp and reducing dandruff.

Will it make your skin darker?
No, it will not make you have a darker complexion. It contains the nutrient Vitamin E, which nourishes your skin, but may also make you more sensitive to the sun if you go outside shortly after applying it to your body.

When can I apply it as a “sunscreen”?
It was traditionally believed to protect your skin from sunburn, but now some scientists are warning that it could actually make your skin more sensitive to the sun.

Can mustard oil be used as a natural sunscreen?
The oil contains Vitamin E, but it should not be relied upon as your main source of sun protection, rather, there is some evidence to suggest that using mustard oil as a primary sunscreen might make your skin more sensitive to sunlight or cause redness for some individuals.

Can it “restart” sensation in numb muscles?
Massaging the body with warm mustard oil is traditionally used to stimulate blood flow and wake up numb or stiff limbs.

Can I use it to remove a tan?
Traditionally, a recipe of mustard oil, chickpea flour, and yoghurt works against dark spots, tan lines and lightens them.

Is it ok to utilize it as “beard oil”?
It can be used, but keep in mind that it does have a strong odor, so it would not be good to use every day in public. It supplies nutrition to the hair and helps in growth, but the scent is too much to handle as an everyday grooming item.

Why do people put it on dry earlobes?
This product has been used for generations to relieve irritation caused by cheap jewelry, because of its unique anti-inflammatory properties.

Is this oil safe for babies?
While historically it has been used in South Asia for massage on infants, modern dermatologists warn that it poses a risk to babies’ skin barrier by way of rashes. The oil products used in traditional applications may be safe, but they are also questionable given present-day research.

Is it safe for a “newborn massage”?
While the oil is common in South Asia to promote warmth and strength, modern child specialists warn that it can damage an infant’s delicate skin.

Mustard Oil for Health

Medicinal qualities of mustard oil are diverse. Mustard oil is not just an oil used for cooking. It also helps in maintaining good health. It is known to boost our immunity and is good for heart health and diabetes patients. Inhaling mustard oil through steam can help clear our respiratory system from congestion. The vitamins present in mustard oil are good for our cells and bones.

Because of its anti-inflammatory effects (through the selenium and omega-3s), using this product in a massage can ease the stiffness of your joints and help with that.

Will it cure asthma?
No, not at all. Inhaling steam mixed with some drops is an often-used traditional method of relieving respiratory mucus.

Is it clinically proven to clean arteries?
There is currently no clinical evidence for the supposed ability of this oil to “scrub” arteries; however, it contains large amounts of Heart-Healthy Mono-unsaturated Fat (MUFA) and Poly-saturated Fat (PUFA) that are believed to support cardiovascular health; so, it helps promote heart health.

What is the effect of mustard oil on Triglycerides (TG) and cholesterol?
It generally helps improve your lipid profile when used in moderation.

1. Effect on Cholesterol: Mustard oil is considered good for heart health, because of its high concentration of Monounsaturated Fatty Acids (MUFA) (~60%) and Polyunsaturated Fatty Acids (PUFA) (~21%). It reduces the bad cholesterol and increases the good cholesterol. Like other vegetable oils, pure mustard oil has zero dietary cholesterol.

2. Mustard oil is rich in Omega-3 fatty acids (alpha-linolenic acid), which lower triglyceride levels and reduces the inflammation.

Does it “scrub” internal organs?
Some people believe that it “cleans” the intestines via its anti-microbial properties, but there is no scientific evidence that it scrubs anything within the body.

Is it an “increase in metabolism” for losing weight?
Some research shows that its pungent compounds might increase metabolism slightly. However, mustard oil is not a miracle cure for weight loss.

Who should avoid or limit mustard oil?

· People with mustard allergy (rare but possible)
· Infants below 6 months (modern doctors warn against massage)
· Those with sensitive skin (do a patch test before using on body)
· People with history of heart issues should consume in moderation due to erucic acid content

Possible side effects of overconsumption:

· Digestive discomfort in some people
· Skin irritation if applied without dilution for some individuals
· Eye irritation if touched accidentally

Note: Always use food-grade mustard oil for cooking. Oils labelled “For External Use Only” should not be consumed.

Dental and Oral Care (OIL PULLING)

Is Swishing with Mustard Oil Safe?
Swishing or “oil pulling” with mustard oil in Ayurveda is believed to strengthen and/or develop the gums by helping to remove plaque causing bacteria from the mouth as well.

Can Mustard Oil and Rock Salt Fix My Tooth Cavity?
While the oil and rock salt paste may be a traditional Ayurvedic remedy for strengthening the gums and reducing plaque but cannot fix a hole in your tooth due to decay.

Does oil pulling with mustard help whiten discolored teeth?
Some think that the salt and oil combination can help remove stains, but it’s unknown if this can make the actual color of your teeth whiter. There is no scientific evidence to support this claim.

Is it safe to swallow the oil after using it to rinse out your mouth?
No, you should spit the oil out, since this is the mass of bacteria and other toxins that were caught up in the oil while you were rinsing your mouth.

Will using mustard oil help cure a toothache?
It might offer some short-term comfort if the gum is swollen, but it won’t eliminate the underlying problem if the infection is deep or there is an abscess present.

Will applying mustard oil to my belly button help with chapped lips?
This is said in an Ayurvedic community. Some people feel that this works for them, but there is no connection between the belly button and the lips. Any success is likely just a part of their ritual for general body hydration.

Can mustard oil be used as a solution for squeaky doors?
Yes, this oil is an excellent natural lubricant for squeaky hinges and will also help to prevent rust on metal tools when used as a coating.

Can Mustard Oil Be Used to Polish Furniture?
Yes. The combination of mustard oil and lemon juice can form a natural wood polish that both cleans and adds an additional hydrophobic surface.

Is there an ability to use it to “waterproof” your leather products?
Yes, it creates a barrier that protects against water, but your leather will darken if you use this product and your item will retain the odor for a long time.

Will Mustard Oil Repel Mosquitoes?
Yes. The strong aroma of this oil is a natural insect repellent. Rubbing small amounts on exposed areas should help to keep mosquitoes away.

Part 4: Purity, Testing & Adulteration

Tests and methods to check purity are discussed here.

General Purity Questions

Why is it not able to be blended with Water?
Oils are hydro-dynamically neutral or “Hydrophobic”, which means they do not bond or mix with water. If an oil blends with water, it is most likely of lesser quality and made with a cheaper oil.

Will it go rancid faster than other oils?
No, it will not go rancid faster than other oils. It contains natural antioxidants like Vitamin E and antimicrobial properties which make it a great preservative for pickles.

What caused my mustard oil to become discolored (green)?
Typically, this is a result of unripe mustard seeds being processed into oil or improper oil processing. Pure mustard oil is reddish-brown or amber in color.

Tests For Adulteration

How do I determine whether my bottle of oil is “fake” by putting it in the freezer?
Put the bottle in the refrigerator. If it freezes or starts to appear to have white spots, then it is likely that the oil has been adulterated with palm oil or some other fat.

Why does it contain industrial chemical smells?
Pure oil has a pungent, sharp aroma due to its natural allyl isothiocyanate compound. Whenever the oil has an odour similar to industrial chemicals, this is an indication that it has been adulterated with a toxic oil (Argemone) which is very dangerous!

Why does my mustard oil look “orange” when mixed with an acid?
If the oil produces an orange red color when mixed with an acid, it has been adulterated with argemone oil and is therefore toxic for human consumption.

Can I test purity with a “barometer”?
Yes, you can test the purity of mustard oil with a barometer. Pure mustard oil typically has a specific reading between 58 and 60.5.

Will it cause “Epidemic Dropsy”?
It will not produce “epidemic dropsy” unless it is contaminated with argemone oil, which is toxic.

Tests For Cooking and Quality

Is “Kachi Ghani” the advertising gimmick?
No, Kachi Ghani” is the traditional method of preserving vegetable oils (like canola) by using wooden mortars (kohlu) and applying no heat in the process.

Is mustard oil poisonous if it has been heated to the point of smoking?
No, traditionally used in Indian cooking, it must have been heated to the smoking point to remove any raw pungent and bitter flavor.

Is all the nutrient value diminished when mustard oil is heated?
No, it has great heat stability, and it has a higher smoke point (approx. 250°C) than most refined oils; therefore, mustard oil retains more of its nutrients during deep frying than most refined oils do.

Is it harmful to heat it to the smoking point?
When you heat mustard oil until it reaches its smoke point, you may be able to use that method to temper the spiciness and pungency of the oil without causing injury to your health. However, if you heat mustard oil past its smoke point, you are also causing the mustard seed oil to break down into potentially dangerous substances.

Will my food be greasier if I fry it in mustard oil?
No, this is not true. Since mustard oil has a high smoke point of 250°C, it cooks food quickly and provides a crispier texture and less grease than if the same food were fried in oils with lower smoke points, such as sunflower or rice bran oil.

Should I mix it with other oils to “neutralize” it?
Many nutritionists suggest using a variety of types of oils so that your body gets all of the nutrients (for example, one day using mustard oil, and the next day using sunflower or rice bran).

Part 5: Legal & Regulatory Information

USA & NORTH AMERICA

Is mustard oil illegal to consume in the USA?
The US Food and Drug Administration (FDA) prohibit using mustard oil as food because it contains too much erucic acid, but you can buy it from stores labelled “For External Use Only.”

Why do US-based Indian grocery stores have a “massage oil” next to lentils?
Because of the FDA prohibition, pure mustard oil must be labelled as only intended for use externally, so some customers buy it specifically so they can use this “massage oil” when preparing their traditional food.

Can I cook with an oil that says, “For External Use Only”?
No, at least legally you can’t. Many do, though health experts suggest that you should not use oils labelled as ‘For External Use Only’ unless they are ‘low-erucic acid varieties’ that are approved for food consumption and are found in your area.

Can I be arrested for eating mustard oil because it is labelled “for external use only”?
You cannot! Labelling indication specifies use by (more appropriately) the FDA guidelines and private kitchen use is not monitored.

INDIA

Is mustard oil illegal in India?
No, it is legal and regulated by the FSSAI, and is an edible oil in India, Bangladesh and Pakistan with strict standards for purity.

UK & EUROPE

Are there differences among the U.K., Europe and the U.S. regarding the legalization of Canola Oils?
Erucic acid is the only reason that there is some Tjalie is not fully illegal. Most of Europe and the U.K. are very similar in law the laws have max quantities allowed of erucic acid when being used as cooking oil.

Part 6: Comparisons and Relationships

Mustard Oil vs Canola Oil

Is canola oil just a fake name for mustard oil?
No, but the two are related. The name canola is formed by combining “Canadian Oil” and “Low Acid,” since canola was bred by crossbreeding rapeseed oil to remove the majority of the erucic acid to become compliant with North American regulations on safety.

Is the potential spread of “Canola” a conspiracy (genetically modified mustard)?
Partially yes, canola oil (Canadian Oil, Low Acid) was bred from rapeseed (mustard) to have less than 2% erucic acid to meet U.S. and Western government standards.

Mustard Oil vs Other Oils

If mustard oil is “toxic” in North America, why is it a staple in India?
The prohibition is based on 1970s rat studies performed in the USA. Humans metabolize erucic acid much better than rats do, plus evidence from thousands of years of traditional use in India shows no signs of large-scale heart disease.

Is mustard oil considered a “biochemical weapon” due to its content of erucic acid?
This claim is based on study results from the early 1970s where rat hearts were examined after high doses of erucic acid. In fact, humans metabolise erucic acid much more effectively than rats do.

Does it “kill” taste buds?
The sharp “zing” found in mustard, caused by allyl isothiocyanate, is likely safe for taste-bud cells as they will adapt to the intensity of the taste.

Can I put it in my ears to stop an earache?
It was used in past to stop an earache. Modern medical science is of the opinion that putting oil in the ear can trap bacteria or lead to infections.

Is it safe to give my cat mustard oil to relieve hairballs?
No, because it can cause serious gastrointestinal issues and be toxic for cats.

Myths vs Facts Quick Table

Part 9: More About Mustard Plant

Mustard is from the Brassica family. The botanical name of mustard is Brassica campestris. When you see a mustard field, it looks like a sea in yellow color. It seems like the field goes on and on as long as we can see. Thousands of mustard flowers bloom together, turning the fields into soft golden landscapes that attract visitors. These mustard fields in places like Kashmir, Punjab and other parts of India/ Pakistan, have become tourist places because of their unique beauty.

Mustard oil has become a part of modern lifestyles even though it came from older generations.
