BLACK MUSTARD Overview Information

Black mustard is a plant. The seed and oil from the seed are used to make medicine.

Black mustard oil is used for the common cold, painful joints and muscles (rheumatism), and arthritis.

Black mustard seed is used for causing vomiting, relieving water retention (edema) by increasing urine production, and increasing appetite.

Some people make a paste by mixing ground black mustard seed with warm water. They pack the paste in cloth and apply the cloth directly to the skin as a “mustard plaster.” This preparation is used for treating pneumonia, pain and swelling (inflammation) of the lining of the lungs (pleurisy), arthritis, lower back pain (lumbago), and aching feet.

In foods, black mustard leaves (greens) are used in salads and other dishes.

Also in foods, black mustard seed is used as a spice and to flavor mustard condiment. There are approximately 40 different species of mustard plant. Three different types are generally used to make the mustard condiment. Black mustard (Brassica nigra) is the most pungent. White mustard (Brassica alba) is the most mild and is used to make traditional American yellow mustard. Brown mustard (Brassica juncea) is dark yellow, has a pungent taste, and is used to make Dijon mustard. It is easier to harvest the brown mustard seed than the black mustard seed, so many mustard condiments now contain brown mustard seed instead of black mustard seed.

How does it work?

There is not enough information available to know how black mustard might work for medical conditions. Black mustard contains chemicals that might initially reduce pain when applied to the skin. But contact with the skin for too long might cause skin irritation and burning.

BLACK MUSTARD Side Effects & Safety

Black mustard is safe when eaten as part of a food such as mustard. But there is not enough information to know if it is safe to use black mustard as a medicine that is taken by mouth or applied to the skin.

Some side effects are known. Taking large amounts of black mustard seed by mouth can damage the throat and can also cause other serious side effects including heart failure, diarrhea, drowsiness, breathing difficulties, coma, and death. When applied to the skin, especially for a long time, black mustard can cause skin blisters and skin damage.

Special Precautions & Warnings:

Pregnancy and breast-feeding: It’s UNSAFE to use black mustard in medicinal amounts if you are pregnant. Black mustard contains chemicals that might start your menstrual period and cause a miscarriage.

It’s also best to avoid using black mustard as a medicine if you are breast-feeding. Not enough is known about the effects it might have on you or your nursing baby.
