Pickled Mustard Seeds (Black, Brown, Yellow) – Side Effects & Health Benefits:

Mustard seeds are from the mustard plant (Brassica oleracea family), which is a cruciferous vegetable related to Brussels sprouts, kale, broccoli, radishes, and cabbage.

The English word ”mustard” is derived from the Latin words ”mustum ardens” literally translating “burning must,” describing the famous grape wine that was combined with ground mustard seeds.

Moreover, an archaic name for the seed is ”eye of newt.” Frequently misinterpreted for the actual eye of a newt, this ancient name of the plant has been popularly linked with witchcraft ever since it was mentioned as an ingredient to a witch’s brew in Shakespeare’s popular play Macbeth.

Mustard seeds are mentioned in the New Testament in which the kingdom of Heaven is compared to a grain of mustard seed. Furthermore, these seeds are also mentioned in ancient Sanskrit writings dating back about 5,000 years ago.

There are three types:

  • white mustard (Brassica alba – these seeds are light straw-yellow colored and are slightly larger than the other 2 varieties);
  • black mustard (Brassica nigra – these seeds are sharp and more pungent than the other 2 varieties);
  • brown mustard (Brassica juncea – these seeds are native to the sub-Himalayan plains of Northern India).
