Iberis amara, called wild candytuft, rocket candytuft and bitter candytuft, is a species of flowering plant in the family Brassicaceae, native to Belgium, France, Germany, Great Britain, Italy, Spain, and Switzerland. It has been introduced to numerous locations including Algeria, Sweden, Eastern Europe, the Caucasus, Iraq, Kazakhstan, the Indian Subcontinent, Korea, Far Eastern Russia, New Zealand, Argentina, Ecuador, Hispaniola, the United States, and Canada. It prefers to grow in warm and sunny conditions, in high-calcium soil.

Description

A cabbage family herb. It is an annual plant. It grows 10-30 cm high. The leaves are simple. The lower leaves are spoon shaped and the higher ones are sword shaped. There can be some teeth near the tip. The flowers are 1 cm across and white or pale violet.

Edible Uses

The seeds can be used as a mustard substitute. Pungency develops when cold water is added to ground seed — an enzyme (myrosin) acts on a glycoside (sinigrin) to produce a sulphur compound, a reaction that takes 10–15 minutes. Using hot water or vinegar, or adding salt, inhibits the enzyme and produces a mild, bitter mustard instead.

Traditional Uses

The seeds are occasionally used as a source of mustard.

It has traditionally been taken for gout, rheumatism and arthritis. All parts of the plant are antirheumatic and antiscorbutic. The seeds are considered especially useful in treating asthma, bronchitis and dropsy. The plant is gathered in summer and can be dried for later use, while seeds are harvested when fully ripe.
