Mustard is one of the oldest spices being used since centuries. The seeds of the plant are grinded and mixed with water to form extensively used condiment called mustard. Mustard seed is also used to manufacture the very popular mustard oil, widely used in food industry. These seeds are an important ingredient in many regional cuisines. The seeds come from three different types of plants: black mustard (B. nigra), brown Indian mustard (B. juncea), and white or yellow mustard (B. hirta/Sinapis alba). The Brassica genus includes broccoli, turnips, radishes, cabbage and cauliflowers. The mustard family also includes plant grown for their leaves, like argula, a number of Oriental greens, as well as mustard greens. Three related species of mustard are grown for their seeds.
