Mustard

Mustard plants come from several plant species (genera Brassica and Sinapis). The most common types of mustard are Sinapis alba (also called Brassica alba, yellow mustard, or white mustard) and Brassica juncea (also called brown mustard or Indian mustard). Black mustard (Brassica nigra) fell out of use in commercial mustard products in the 1950s.

BACKGROUND

Mustard plants come from several plant species (genera Brassica and Sinapis). The most common types of mustard are Sinapis alba (also called Brassica alba, yellow mustard, or white mustard) and Brassica juncea (also called brown mustard or Indian mustard). Black mustard (Brassica nigra) fell out of use in commercial mustard products in the 1950s.

Mustard has a long history of use. Traditionally, mustard or mustard oil have been used as a treatment for stomach and intestinal disorders and diabetes, as a natural antibacterial agent, to stimulate vomiting, and as a massage oil to improve blood circulation, muscular development, and skin texture. Mustard plaster (a mixture of flour and mustard powder) has been traditionally applied to the chest and abdomen to promote healing. Today, the primary use of mustard is as a condiment.

The pungency of mustard comes from its isothiocyanate compounds. Mustard oil is a pungent plant extract from mustard seed, horseradish, and wasabi, and its main constituent is allyl isothiocyanate. Although it is used in India and elsewhere as a cooking oil, high doses injected or applied topically can cause irritation and inflammation.

There is limited human evidence in support of the use of mustard plaster for bronchitis or for the use of mustard oil in prevention of heart attack. Evidence is conflicting as to whether mustard oil is effective at lowering cholesterol levels or as to its beneficial effects as a massage agent in infants. At this time, high-quality human trials in support of the use of mustard or mustard oil for any indication are limited. Better-designed clinical trials are needed before recommendations can be made regarding taking mustard for any condition.

EVIDENCE TABLE

Conditions

Uses
disclaimer: These uses have been tested in humans or animals. Safety and effectiveness have not always been proven. Some of these conditions are potentially serious, and should be evaluated by a qualified healthcare provider.
Grade*

Chronic bronchitis

In human study, a plaster containing white mustard seed was as effective as a traditional Chinese bronchitis treatment. Additional study is needed in this area.

C

Heart attack (acute myocardial infarction)

In human study, mustard oil consumption in the diet of patients with a heart attack resulted in a decrease in further heart problems. In further dietary study, consumption of mustard oil, as well as other foods (vegetables, legumes, walnuts, almonds, whole grains, and soybean oil) resulted in reduced risk of heart attack and deaths due to heart problems. Additional study is needed in this area.

C

High cholesterol

In human study, inclusion of mustard oil in the diet resulted in little benefit in terms of cholesterol levels. Additional study is needed in this area.

C

Infant development / neonatal care

Mustard oil is used topically in newborn care as part of a traditional oil massage for neonates in many developing countries. Reasons include promotion of strength, maintenance of health, and provision of warmth. In human study, daily massage with oils, including mustard oil, improved growth and postmassage sleep in infants. However, in animal study topical mustard oil caused toxic effects on the skin. Additional study is needed in this area.

C

*Key to grades: A: Strong scientific evidence for this use; B: Good scientific evidence for this use; C: Unclear scientific evidence for this use; D: Fair scientific evidence against this use (it may not work); F: Strong scientific evidence against this use (it likely does not work).

Some of these conditions are potentially serious, and should be evaluated by a qualified healthcare provider. There may be other proposed uses that are not listed below. Antiaging, antibacterial, antifungal, antimicrobial, antioxidant, antiviral, arthritis, asthma, blood circulation stimulant, blood vessel dilation, burns, cancer, detoxification, diabetes, digestion, diuretic, duodenal ulcer, ear infection, emetic, food preservation, gastric acid reduction, gastric ulcer, high blood pressure, high blood sugar/glucose intolerance, laxative, lupus, mosquito repellent, pain relief, parasites, respiratory problems, ringworm (tinea capitis), skin conditions, stomach problems.

DOSING

disclaimer: The below doses are based on scientific research, publications, traditional use, or expert opinion. Many herbs and supplements have not been thoroughly tested, and safety and effectiveness may not be proven. Brands may be made differently, with variable ingredients, even within the same brand. The below doses may not apply to all products. You should read product labels, and discuss doses with a qualified healthcare provider before starting therapy.

Adults (18 years and older)

Three tablespoons of powdered mustard has traditionally been used to induce vomiting. 14 grams of dry mustard has been used as a laxative.

For high cholesterol, mustard oil as 25% of total energy intake has been used for eight weeks. For heart benefits, 2.9 grams of mustard oil has been used daily for one year.

For bronchitis, a plaster containing mustard (one teaspoon of flour with © teaspoon of mustard) has been applied to the chest for eight hours.

Children (younger than 18 years)

In infants, 20 milliliters of mustard oil has been massaged onto the skin daily for four weeks. Caution is advised, as some reports have warned that application of mustard oil to the skin of infants is potentially toxic.

SAFETY

disclaimer: The U.S. Food and Drug Administration does not strictly regulate herbs and supplements. There is no guarantee of strength, purity or safety of products, and effects may vary. You should always read product labels. If you have a medical condition, or are taking other drugs, herbs, or supplements, you should speak with a qualified healthcare provider before starting a new therapy. Consult a healthcare provider immediately if you experience side effects.

Allergies

People with a known allergy or hypersensitivity to mustard and other members of the Brassicaceae family (e.g., cabbage, cauliflower, turnip, Chinese cabbage, rapeseed, radish, or horseradish), nuts, legumes, corn, Rosaceae fruit, mugwort pollen, turnip rape, Brazil nut, peach, melon, or cashews should avoid mustard and mustard oil. Also, children with sensitivities to cow's milk, egg, wheat, and pollens (birch, timothy, or mugwort), should avoid mustard, as they are more likely to react to mustard and rapeseed. Both local (e.g., skin) and whole body reactions, such as anaphylaxis, are possible. Respiratory (e.g., nose, sinus, and lung) reactions are also possible.

Side Effects and Warnings

Mustard oil applied to the skin may increase pain sensitivity, burns, inflammation, itching, rash, and coloring changes (pigmentation). Breathing in ground mustard seeds may cause airway irritation and inflammation.

Mustard may lower blood sugar levels. Caution is advised in patients with diabetes or hypoglycemia and in those taking drugs, herbs, or supplements that affect blood sugar. Blood glucose levels may need to be monitored by a qualified healthcare professional, including a pharmacist. Medication adjustments may be necessary.

Mustard may decrease the risk of bleeding. Caution is advised in patients with bleeding disorders or those taking drugs that affect bleeding. Dosing adjustments may be necessary.

Use cautiously in patients with cardiovascular conditions, cancer, gastrointestinal conditions, and iodine deficiency.

Avoid the use of mustard oil in high doses.

Mustard should be purchased from trusted sources to avoid consumption of mustard plants grown in soils contaminated with heavy metal or other toxins. Wash mustard leaves carefully before use.

Pregnancy and Breastfeeding

Large amounts of mustard or mustard oil should be used cautiously in pregnant women, due to lack of safety information. Use of mustard in food preparation is likely safe.

INTERACTIONS

disclaimer: Most herbs and supplements have not been thoroughly tested for interactions with other herbs, supplements, drugs, or foods. The interactions listed below are based on reports in scientific publications, laboratory experiments, or traditional use. You should always read product labels. If you have a medical condition, or are taking other drugs, herbs, or supplements, you should speak with a qualified healthcare provider before starting a new therapy.
