Cochlearia officinalis, common scurvygrass, scurvy-grass, or spoonwort, is a species of flowering plant in the family Brassicaceae.

[7][8] The specific epithet officinalis refers to the Linnaean term for plants with an established medicinal, culinary, or other use.

[4][6] It is found within Eastern Europe, in the Russian Federation, (within the Administrative centre of Arkhangelsk, Komi, Murmansk and Nenets).

[4] In Ireland, it prefers saltmarshes, coastal cliffs and walls, and rocky, muddy seashores.

[3] It was once used by herbalists as a cure for scurvy, as the plant contains Vitamin C.[2] Nicholas Culpeper wrote of scurvygrass in his book Complete Herbal that its chief good effect is when used "by those that have the scurvy" and that it "is of singular good effect to cleanse the blood, liver and spleen, taking the juice in the Spring every morning fasting in a cup of drink".

Scurvygrass drinks and sandwiches were a popular in the UK until the mid-19th century, when citrus fruits became more readily available.
