What is Mustard?

Mustard is a versatile cruciferous vegetable which belongs to the Brassica family, similarly to broccoli and cabbage. Native to the temperate areas of Europe, it was amongst the earliest grown crops in the region. For thousands of years, the mustard plant has been quite popularly cultivated in North Africa, Asia, and Europe more like an herb; it was even popular among the ancient Greeks and Romans.

Presently, mustard is grown in over 21 countries with major production happening in Europe, Nepal, Canada, Ukraine, and India. Attributing to its flavor and therapeutic nature, usage of mustard is quite popular all around the globe with approximately 700 pounds consumed annually.

It is a multi-faceted botanical with a number of different varieties. Three variants out of these varieties – namely white mustard (Brassica alba,) black mustard (Brassica nigra), and brown mustard (Brassica juncea), have gained more popularity over others, and are commercially grown and used for their young flower stalks, leaves, and seeds. White mustard (sometimes referred to as yellow mustard) has a milder taste and is normally used in the preparation of the famous American yellow mustard condiment. Black mustard is popular for its strong aroma and flavor while brown mustard, also used to prepare Dijon mustard, offers a sharp pungent taste.

Health Benefits of Mustard

Phenolic components and other valuable nutrients present in different parts of the mustard plant such as seeds, leaves, and oil collectively offer a magnitude of health benefits with a unique flavor. The efficacy of the mustard plant for therapeutic usage is discussed below:

Possible Anti-cancer Properties

Being a member of the Brassica family, the seeds of a mustard plant contain generous amounts of healthy phytonutrients called glucosinolates which can prove valuable against various cancers such as the bladder, colon, and cervical cancer. Glucosinates break down to form isothiocyanates with the help of myrosinase enzymes present in mustard.

According to a study published in the journal Human & Experimental Toxicology, mustard seeds may have chemopreventive potential and protect against toxic effects of carcinogens. A group of US researchers found that allyl isothiocyanate-rich mustard seed powder may help lower the risk of bladder cancer.

A study led by Yuan H, et. al. found that mustard seeds may help prevent cancer such as colon cancer due to the presence of anti-oxidants.

Various studies have suggested that the anti-cancer effects of these components inhibiting the growth of cancer cells and even guard against the formation of such malignant cells. The chemopreventive properties of its seeds help in restoring the levels of glutathione and stimulate the induction of apoptosis without affecting the normal healthy cells. However, further research is needed to explore the beneficial effects of mustard seeds.

Relieves Symptoms of Psoriasis

The tiny mustard seeds are effective against psoriasis, which is a chronic inflammatory autoimmune disorder. Research studies have shown the efficacy of mustard seed as an anti-inflammatory agent, and as part of future psoriasis treatments.

According to the study, use of these seeds also stimulates the activities of beneficial enzymes, such as superoxide dismutase, glutathione peroxidase, and catalase, which encourage protective and healing action in such diseases.

Relief from Contact Dermatitis

Mustard seeds offer therapeutic relief in contact dermatitis. Investigative research has suggested that consumption of its seeds in animal models helps in healing the symptoms associated with contact dermatitis such as healing of tissues and reduction in the ear swelling. This has positive implications for relief in humans.

Improves Cardiovascular Health

Mustard oil is a hearty choice when it comes to choosing cooking oil. Studies conducted to assess its effects on the patients suspected of a heart attack demonstrated positive results with respect to reduction in the rate of cardiac arrhythmia, decrease in the ventricular enlargement and the chest pain associated with it. The cardioprotective properties of mustard oil are possibly attributed to the presence of omega-3 fatty acids among other helpful components. This initial research is promising for future studies examining mustard seed and its cardiovascular implications.

Relief from Respiratory Disorders

In folk medicine, mustard seeds have been valued for their therapeutic effects in curing cold and sinus problems. It is considered a wonderful decongestant and expectorant, which helps in clearing the mucus in the air passage. In Ayurveda, its seeds are considered as a food with the warmer tendency and are prized for its healing effects in calming vata and kapha. Since ages, different home remedies have involved the usage of mustard seeds or oil for treating a range of sinus-related ailments. They include the addition of ground mustard seeds in a foot soak for releasing the congestion in the respiratory organs, another one is gargling with tea made of mustard seeds for soothing a sore throat to name a few.

In ancient medicine, the seeds have also been found effective in relieving chronic bronchitis. During an asthmatic attack, massaging a mix of mustard oil and a small amount of camphor promotes easy breathing by breaking down phlegm. Plaster or poultice made of its seeds has been used since olden times for providing relief from bronchitis and to stimulate healthy blood circulation in the body.

Treats Aches & Pains

Poultice, or plaster, made from mustard seeds helps in reducing pains and spasms, as well. Mustard has rubefacient (redness producing) properties and hence when applied as a plaster, exercises analgesic effects and provides relief from muscular aches. Another important advice to note here is that mustard plaster has warmer effects and may cause sore blistering if applied directly on the naked skin. To avoid that, a linen sheet should be used between the skin and the plaster.

Poison Repulsion

In folk medicine, it is considered that mustard seeds possess protective emetic qualities, which resist the effects of poison on the body. A decoction made with its seeds helps in cleansing the body especially if the poisoning is caused by narcotics or excess intake of alcohol.

Antifungal Effects against Ringworm

Some sources claim that anti-bacterial properties of mustard seeds have been shown effective in curing the lesions caused by ringworm. Topical application of a paste made of mustard seeds on clean skin washed with warm water helps in soothing the symptoms associated with ringworms.

Skin & Hair Care

Mustard serves as a wonderful beauty aid as well. Henna leaves boiled with mustard oil are thought to help stimulate healthy hair growth. Mustard seeds, roasted in sesame or coconut oil, enrich the resultant sieved oil and make it an effective cure for acne to promote a clearer complexion.

Healing Effect on Nerves

In folk medicine, the mustard plant is considered to have “heat inspiring” nature, which is thought to benefit some individuals suffering from nerve damage. It helps in stimulating the healing process by arousing the impulses and has an invigorating effect on the nerves.

Helps Control Diabetes

Mustard leaves may also be helpful for those with diabetes. Studies have demonstrated that mustard seed may be beneficial in reducing the damage caused by oxidative stress associated with this chronic disease. Another study examined the administration of mustard oil, in vivo, and found it can help in reducing the levels of glycosylated proteins and serum glucose. It aids in reducing lipid peroxidation and stimulates glucose metabolism as well.

Cholesterol-Lowering Ability

Leaves of the mustard plant have tremendous cholesterol-lowering power. Studies have shown that cruciferous vegetables, in particular, mustard greens have an amazing ability to bind bile acids in the digestive tract which facilitate easy excretion of these acids from the body. The bile acids usually comprise of cholesterol, so ultimately the binding process helps in reducing the cholesterol levels of the body. Another noteworthy fact here is that steamed version of mustard green has better bile acid-binding as compared to the raw version. So steam them lightly, and maybe, add little-roasted cumin, salt, and pepper and enjoy. 

These greens are a nutritional powerhouse and instrumental in reducing the development of blockages in the arteries, thus reducing–and hopefully helping to mitigate disorders like atherosclerosis. Vitamin B6 content present in these greens prevents the platelets from clumping and moderates the risk of thrombosis.

Relieves Menopausal Symptoms

Mustard greens may prove valuable for women during the menopausal phase. Magnesium, along with calcium, encourages bone health and prevents bone loss associated with menopause. It helps in recompensing the low magnesium content in bones and may, along with a healthy diet, help reduce the risk of osteoporosis in menopausal women.
