Centaury

A genus of about 40 species of annuals and biennials, occasionally perennials, found throughout temperate regions. One or two species are grown as ornamentals for their colorful flowers, and a few have medicinal properties. Best known is C. erythraea, which , in common with many members of the gentian family, is extremely bitter, prompting Nicholas Culpeper to comment, in The English Physician Enlarged, or the Herbal (1653) that "it is very wholesome, but not very toothsome". Its constituents include bitter glycosides that stimulate the liver and gall bladder, increasing bile flow and improving the appetite and digestion. Bitter compounds are also present in C. chilensis (canchalagua), a similar plant that grows on the west coast of N America. Bitters are at their most effective taken 30 minutes before eating.

Variable, small biennial or short-lived perennial with a basal rosette and elliptic, veined leaves to 5cm (2in) long. Five-petaled, pink flowers are borne in dense clusters on long, branched stalks in summer.
