Centaurium erythraea

This is an erect biennial herb which reaches half a meter in height. It grows from a small basal rosette and bolts a leafy, erect stem which may branch. The triangular leaves are arranged oppositely on the stem and the erect inflorescences emerge from the stem and grow parallel to it, sometimes tangling with the foliage. Each inflorescence may contain many flowers. The petite flower is pinkish-lavender and about a centimeter across, flat-faced with yellow anthers. The fruit is a cylindrical capsule.

It flowers from June until September.

This centaury is a widespread plant of Europe (including Scotland, Sweden and Mediterranean countries,[2]) and parts of western Asia and northern Africa. It has also naturalised in parts of North America,[2] and throughout eastern Australia, where it is an introduced species.

It is also commonly known as “feverfoullie”, “gentian” or “centaury”.[2]

The European centaury is used as a medical herb in many parts of Europe. The herb, mainly prepared as tisane, is thought to possess medical properties beneficial for patients with gastric and liver diseases.[3]

C. erythraea contains phenolic acids, including ferulic and sinapic acids, as well as sterols (as brassicasterol and stigmasterol), secoiridoid and the glycosides, swertiamarin and sweroside.[2]
