Mustard oil is versatile and used in many parts of the world. It is popularly known as Sarson ka Tel in India and is a key ingredient found in every kitchen. Mustard oil has a strong flavour and enhances the taste of several dishes. Not only that, but it also has numerous health benefits.
But with the fear of cholesterol and an upswing in heart diseases, many people have now become cautious of the kind and quality of oil that they consume on a daily basis. This has led to a widespread increase in the sale of healthy oils such as Olive oil, Sunflower oil, Rice Bran oil and Grapeseed oil.
It is also worth noting that mustard is good for diabetes, owing to its anti-inflammatory properties. So, it is considered one of the ideal oils that can be used in recipes for diabetes.
Mustard oil has about 60% monounsaturated fatty acids(MUFA)(42% erucic acid and 12% oleic acid); it has about 21% polyunsaturated fats(PUFA) (6% omega-3 alpha-linolenic acid(ALA) and 15% omega-6 linoleic acid(LA)) and it has about 12% saturated fats1.
This optimum ratio of omega-3 and omega-6 fatty acids and low content of saturated fats makes mustard oil more beneficial and preferred over several other oils available in the market.
Mustard oil is reddish-brown or amber in colour and is known for its strong smell and pungent, sharp flavour. The pungency of mustard oil is due to the presence of allyl isothiocyanate. This fatty vegetable oil is obtained by pressing mustard seeds.
For now, let’s understand Mustard Oil and its benefits in detail.
Mustard oil is a healthy edible oil it is low in Saturated fatty acids (SFA), high in MUFA and PUFA, especially alpha-linolenic acid and has a good LA: ALA ratio (6:5).
In Myocardial infarction (MI) patients using mustard oil, there was a reduction in arrhythmias, heart failure and angina2. Thus, mustard oil is considered a healthy choice for patients with cardiovascular disorders.
N6 (linolenic acid) and N3 (alpha-linolenic acid) are essential fatty acids that have been proven to be beneficial for the body. N6 PUFA lowers LDL cholesterol but can also decrease HDL3, whereas N3 PUFA may lower triglycerides, blood pressure, inflammation, improve vascular function and sudden death.
Since ancient times, mustard oil has been used to soothe colds, coughs and other respiratory illnesses and allergies.
Inhaling steam containing mustard oil has been shown to clear respiratory congestion4. Also, a concoction made by heating mustard oil, a few cloves of garlic and 1 teaspoon of ajwain, when massaged on our feet and chest, provides relief from cold and cough. Mustard oil may also show positive effects in patients suffering from sinusitis4.
Glucosinolate, available in mustard oil, which accounts for antibiotic, fungicidal and cancer prevention qualities, serves as a therapeutic for human health. It thus protects us from colorectal and gastrointestinal cancers5.
Allyl isothiocyanate serves as an antifungal agent, which protects food from fungal growth and reduces infection5.
Mustard oil is a major source of all fats required by our body to perform diverse biological functions as components of plasma, cell lipids and cell membranes. Mustard oil reduces cholesterol and improves the membrane structure of red blood cells (RBC)6.
Mustard oil is a natural stimulant that is known to stimulate our sweat glands, thereby improving blood circulation throughout the body. By increasing blood circulation in the entire body, it also relieves and rejuvenates stressed and overworked muscles. It also helps to lower body temperature and remove toxins from the body7.
A regular massage with mustard oil helps in relieving aching joints and muscles. Arthritis patients also experience relief and comfort after a massage with mustard oil, thanks to the presence of Omega-3 fatty acids that help to ease stiffness and pain caused due to arthritis8, 9.
The composition of mustard oil is based on our body’s requirements. This oil has <7% saturated fat, high amounts of monounsaturated fatty acids, ranging from 3.6-32.2%. It also contains a considerable amount of linoleic (18:2) and linolenic acids (18:3)6.
The optimum range of omega-3 and omega-6 fatty acids and vitamin E provides the required nutritional value and boosts our immune system6.
The amount of vitamin E in the alpha-tocopherol present in mustard oil has beneficial effects in controlling diabetic hazards5.
Trans fat is the major cause of insulin failure and high oxidation of fat. The absence of trans fat in mustard oil thus helps maintain insulin levels, which in turn regulates our blood sugar levels.
Mustard oil is extremely useful and can be consumed by people who are underweight. It makes you want to eat more by pumping your stomach and facilitates the secretion of gastric juices and bile, which is known to create the feeling of hunger10.
Research suggests that mustard oil may also help in slowing down the growth and spread of certain types of cancer cells in your body11.
Massage in infancy with mustard oil helps improve growth and post-massage sleep. Massage with mustard oil helps improve the weight, length and midarm and midleg circumferences as compared to infants without massage12.
Mustard oil helps strengthen your gums and makes it easier to remove the plaque. Plaque is generally formed due to bacteria that are surrounded by fatty membranes. Swishing mustard oil in our mouth can help loosen the fat-soluble bacteria and further prevent gum bleeding.
Mustard oil contains alpha fatty acids that keep our hair hydrated and lively and help it to grow faster10. Mustard oil is also a rich source of antioxidants, minerals like iron, calcium and magnesium and vitamins like A, D, E and K, all of which are important for hair growth.
The antifungal properties of mustard oil also prevent the development of fungus and dandruff on our scalp7.
Mustard oil is rich in vitamin B complex, vitamin A, vitamin E, calcium, protein and omega 3 fatty acids. This helps reduce fine lines and wrinkles13. It also helps to remove tan from the skin. Mustard oil also works wonders if you have chapped lips.
The anti-bacterial and anti-fungal properties of this oil prevent the development of acne and keep our skin clean and glowing4.
In my experience, I have found that mustard oil has been traditionally used as a rubefacient and irritant due to its topical irritant effects. When applied to the skin, mustard oil can cause a warming sensation and increased blood flow to the area, which may help alleviate pain.

Mustard and sunflower oil are the two most used oils in India. The consumerist-oriented market has spoiled people with choices, with avocado, groundnut, and olive oil running the race as well. With being the two most popular cooking oils, the debate on which ranks higher in benefits has been going on for a long time.
Mustard oil, derived from mustard seeds, is dark yellow and has a pungent odour. Mustard oil is widely used as cooking oil in major Indian households, as it has the benefit of not accumulating in the blood vessels. It contains healthy fats like omega-3 and 6, along with helping reduce cholesterol levels. Mustard oil for hair oiling has been used for centuries. Consumption of mustard oil is recommended to be done in moderate amounts, as it contains considerable amounts of erucic acids. Too much mustard oil can cause anaemia or diarrhoea.
On the other hand, refined sunflower oil is a chemically-treated oil that has been made to look clearer by removing impurities, contaminants and odour. Not many benefits of refined oil besides the fact that it is made to cater to the customers’ needs, like refined oil for heart patients. The harmful effects of refined oil are based on the fact that it is chemically treated. The process of refining involves nickel, in addition to sodium hydroxide and preservatives, which are harmful to the digestive system in the long run.
