Centaury is a small, erect herb that is native to North Africa, Europe and Western Asia. This annual herb has also been naturalized in North America. The herb has a square stem that grows to a height of 15 cm to 30 cm (around 6-12 inches) branching significantly near the top. The stem emerges from a clump of small and broad leaves having an oval shape. In fact, the leaves at the base of the stem form a decoration. However, the leaves growing on the stem are relatively smaller, have a pale green hue, and are lance-shaped and structured in pairs at regular spaces. The stem of centaury bears bunches of striking red or pink colored flowers resembling stars and having yellowish stamens during the period between summer and middle of autumn.

Centaury belongs to the Erythraea genus and the genus name of this herb has been drawn from the Greek word ‘erythros' denoting red - the color of centaury flowers. Earlier, the genus Erythraea was known as Chironia, derived from the name Centaur Chiron, an eminent personality in Greek mythology who was well-known for his talent in herbal medicines and is believed to have healed his wound sustained accidentally from a septic (poisoned) arrow dipped in the blood of hydra with herbs. In fact, the English name of the herb also originated from Centaur Chiron.

Centaury tastes extremely bitter and, hence, people in ancient times called it Fel Terrae meaning the ‘Gall of the Earth'. In old English, the herb was called Felwort which also denotes the ‘Gall of the Earth' and this name is applicable for all the plants belonging to the Gentian family. Centaury is also believed to be the ‘Graveolentia Centaurea' of Virgil, which was nicknamed ‘tristia' by the Lucretius owing to the same reason - the intense bitter taste of the herb. As the bitter taste of the centaury is responsible for its curative and tonic properties, occasionally centaury is also referred to as Febrifuga as well as Feverwort. Another popular name of centaury is Christ's Ladder. In effect, this herb is also known as Centaury Gentian, Red Centaury, Century, Felwort and Centory.

It may be noted here that centaury is considered to be the most effective herb among all the plants having bitter flavour and exceptional common tonics or stimulating properties. Centaury possesses the same antiseptic properties that are found in the buckbean and the field gentian.

Several species of centaury exist and among them, the centaury, scientific name Erythraea centaurium, is an annual plant having a yellow hued, tough and timbered root. The stem of this variety of centaury has a square shape, is stiff, and erect. Centaury bears light green colored leaves that are smooth and glossy with undivided borders. The leaves at the base of the centaury are larger compared to the others and have an oblong or compressed shape. They are tapered at the base and rounded at the end forming a scattering cluster at the bottom of the herb. On the other hand, the leaves growing on the stem do not have any stalk and have pointed tips resembling a lance. The leaves on centaury stem appearing in pairs reverse to one another are slight intermissions.

The apex of the stem of centaury is coroneted by flat clusters or corymbs of rose-hued blossoms resembling stars. The flowers of centaury possess five bifurcated corollas. The flowers also have five stamens. It is interesting to find the anthers coiling in a strange manner once they get rid of their pollens. Although centaury and the plants belonging to the genus Gentiana have close similarities, the form of the anthers after pollination makes them distinct from each other. In fact, the similarities between these two had led some botanists in the early days to classify the genus Gentiana as Centaury Gentian or Gentiana centaurium. The flowers of centaury only bloom when the weather is pleasant and they never open after mid-day.

It may be noted that to a great extent, species of Centaury differ depending on the conditions where they are grown. In effect, several botanists have categorized some of the different types of Centaury. For instance, the dwarf centaury (scientific name, E. pulchella), which is a tiny plant having an extremely lean stem and just one or two flowers with stalks, more frequently only one flower and usually found growing on sandy seashores, particularly in the western region of Europe has been singled out at Newquay in Cornwall. Similarly, the dwarf tufted centaury (scientific name, E. littoralis) is an undersized plant having large leaves and blossoms packed in some sort of an apex are found on grassy sea cliffs. Another such species of centaury known as Broadleaved Centaury (scientific name, E. latifolia) has even larger leaves compared to the tufted centaury. This species of the plant bears blossoms in branched clusters, while the principal stem is separated into three branches.

Apart from the Centaury species found in England, further species grown in the southern regions of Europe, the Azores and other places bear flowers that have a yellowish or pink hue. These species are, however, generally cultivated in gardens.

As discussed earlier, the herb centaury has derived its name from the legendary centaur in Greek mythology named Chiron, who is believed to be an expert in herbal medications. The term erythrae too has been drawn from the Greek word denoting red and refers to the red colored flowers of the herb. The early Celts believed that Centaury brought good luck, while the herbal medicine practitioners in Scotland often prescribed the use of the herb to heal snake bites as well as other venoms. It is interesting to note that during the Middle Ages people were of the view that centaury was a supernatural herb that helped in driving evil spirits away. The flowers of centaury are etched on the tomb of the renowned English poet William Wordsworth, who was an admirer of nature. William Wordsworth considered the centaury flowers that only open up during the day time and again shuts up in the evening as the rising sun!

Centaury belongs to the gentian family and similar to all other members of this plant family, centaury encloses numerous compounds having bitter flavours. These bitter compounds are beneficial for the proper functioning of the liver and the gall bladder and, thereby, stimulate the digestive process and also help in augmenting appetite.
