Overview Information

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

Black mustard is used for the common cold, joint pain, arthritis, lung illnesses, and other conditions, but there is no good scientific evidence to support these uses.

In foods, black mustard leaves (greens) are used in salads and other dishes. The seed is used as a spice and to flavor mustard condiment. There are approximately 40 different species of mustard plant. Black mustard (Brassica nigra) is the most pungent.

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.


Uses & Effectiveness?

Insufficient Evidence for

  • Common cold.
  • Joint pain.
  • Osteoarthritis.
  • Water retention (edema).
  • Loss of appetite.
  • To induce vomiting.
  • Pneumonia and painful lung conditions, when applied to the affected area as a "mustard plaster".
  • Aching feet, when applied to the affected area as a "mustard plaster".
  • Lower back pain, when applied to the affected area as a "mustard plaster".
  • Other conditions.
More evidence is needed to rate the effectiveness of black mustard for these uses.

Side Effects

Side Effects & Safety

When taken by mouth: Black mustard is LIKELY SAFE when eaten as part of a food such as mustard. But there isn't enough reliable information to know if black mustard is safe to use as medicine. It might cause side effects such as throat damage, heart failure, diarrhea, drowsiness, breathing difficulties, coma, and death when used in very large amounts.

When applied to the skin: There isn't enough reliable information to know if black mustard is safe. It might cause side effects such as skin blisters and skin damage, especially when applied for a long time.

Special Precautions & Warnings:

Pregnancy: It's LIKELY 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.

Breast-feeding: There isn't enough reliable information to know if black mustard is safe to use when breast-feeding. Stay on the safe side and avoid use.

Diabetes: Black mustard might lower blood sugar levels when taken as a medicine. If you have diabetes and take medications to lower your blood sugar, adding black mustard might make your blood sugar drop too low. Monitor your blood sugar carefully.

Surgery: There is a concern that black mustard might interfere with blood sugar control during and after surgery when taken as a medicine. Stop using bitter melon at least 2 weeks before a scheduled surgery.
