Rhamphospermum arvense, commonly known as charlock mustard or field mustard, is an annual plant that can reach heights of 20-80 cm but can exceed one meter under optimal conditions. It has erect, branched stems with coarse spreading hairs, especially near the base. The leaves are petiolate and vary in shape from oblong to lanceolate. The plant blooms from May to September, producing yellow flowers with four petals and spreading sepals. The fruit is a silique 3-5 cm long with a beak 1-2 cm long. The seeds are dark red or brown and smooth, measuring 1-1.5 mm in diameter.

The plant contains glucosinolates, including sinalbin. The seeds also contain gibberellic acid, which affects seed dormancy.
The leaves of wild mustard are edible when the plant is young and are usually boiled. The seeds can be ground to produce mustard. Oil extracted from the seeds has been used for lubricating machinery. As ruminant feed, grazing wild mustard at growing and flowering stages is harmless for cattle and sheep. However, poisoning can occur if older seed-bearing plants are consumed.
