This was based on a description by the Swedish botanist Carl Linnaeus. The Latin specific epithet nigra is derived from the Latin word for black. This is due to the black seeds. 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.
