The Sea, the Sea

The Illyrians (and later the Romans) considered Iris illyrica a medicinal plant with various medicinal properties. These included the healing of boils and relief of headaches. Parts were used in the ancient world as an anti-perspirant and for the manufacture of perfumes. 

Professor Mundeign's research suggested that it is actually identical to the Dalmatian Iris (Iris pallida). He acknowledges however that according to the International Organization for Plant Information the status of this plant is still unresolved, though it has been reclassified by some as a synonym of Iris pallida subsp. illyrica. Either way, its use in the treatment of sea-sickness has been controversial.
