History: Its name derives from the Centaur, Chiron, the great healer in Greek mythology, who is supposed to have cured himself from an arrow wound, poisoned with the blood of the hydra, with the herb; erythrea is Greek for “red” -the colour of the flowers The ancients named it Fel terrae, “gall of the earth”, due to its extreme bitterness and was among their ‘fifteen magical herbs’. Saxon herbalists, in the manner of Chiron, prescribed it for snakebites and poisoning and also to bring down fevers- hence the common name of Feverwort. (Smith, 1977)

Traditional and Practitioner sources:
“it opens obstructions of the liver, gall and spleen, helps the jaundice, and eases the pain in the sides and hardness of the spleen…It is very wholesome, but not very toothsome.” Culpeper, 1653 (Culpeper, 1995: 63)

“A most excellent tonic and strengthener, which will assist the heart, is an infusion of half-an-ounce each of Centaury and Raspberry leaves and a teaspoonful of Cayenne pepper…” William Smith (1977: 43)
