Black Mustard

Black mustard is an annual herb of the mustard family, now classified as Rhamphospermum nigrum, with yellow flowers and small dark brown to black seeds. It is native to Europe, North Africa and parts of Asia and has been cultivated in India for centuries.

Known in Ayurveda as Rajika, the pungent seed is a familiar kitchen spice. It has traditionally been used in warming external preparations and oils for joint comfort, and in digestive spice blends in household practice.
