Indian mustard, or Brassica juncea (L.) Czern & Coss., is a member of the mustard family, or Brassicaceae (Cruciferae) family of plants. Out of all the rapeseed and mustard crops grown in India, Brassica juncea is the most common, covering more than 90% of the land. B. juncea is produced as a pure crop or in combination with other crops as wheat, lentil, chickpea, pea, sugarcane, linseed, etc. in marginal and sub-marginal lands. It is cultivated mostly for its seeds, which provide an essential oil and condiment, even though it is widely and extensively grown as a vegetable. There are two main cultivated types of rapeseed-mustard crops: winter type and spring type. Young plants' leaves are consumed as green vegetables. Rheumatism, rheumatic pain, and muscle soreness have all been traditionally treated with mustard oil and seeds. Mustard oil is used topically to the scalp in India with the belief that it will promote hair growth. Ground mustard seeds have laxative, stomach mucosa-stimulating, and intestinal secretion-inducing properties.
