Botanical name: 

Iberis. Iberis amara L. Bitter Candytuft.—A small European herbaceous cruciferous plant. 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.
