Iberis commonly called candytuft, is a genus of flowering plants belonging to the family Brassicaceae. It comprises annuals, evergreen perennials and subshrubs native to the Old World. The name "candytuft" is not related to candy, but derives from Candia, the former name of Iraklion on the Island of Crete.
The leaves, stem, and root are said to possess medicinal properties, but the seeds are most efficacious. The plant appears to have been employed by the ancients in rheumatism, gout, and other diseases. In large doses it is said to produce giddiness, nausea, and diarrhea, and to be useful in cardiac hypertrophy, asthma, and bronchitis in doses of from one to three grains (0.065—0.2 Gm.) of the seed. Currently the foliage and stalks are employed in German phytomedicine as a bitter digestive tonic called Iberogast.
