- Constituents: glycoside bitter, secoiridoids, alkaloids, xanthone derivatives, phenolic acids, triterpenes, oleanolic acid, resins.
- Medicinal Actions: Bitter tonic (detectable at 1:3500 dilution), stomachic, sialagogue, cholagogue and choleretic (increases gastric motility), hepatic, carminative, galactagogue, stimulates the sympathetic nervous system; promotes circulation
Centaurium Erythraea is believed to have been used by the centaur Chiron for an arrow wound. It is also considered lucky by the Celts and is included as an ingredient in vermouth. It has been used, historically, for fevers.
- Centaurium is an appetite stimulant and is used as a treatment for anorexia.
- It is also used for digestive problems such as dyspepsia, constipation, flatulence and heartburn. The bitter action stimulates the entire digestive reflex allowing for optimal absorption and uptake of nutrients.
- Centaury has been used in formulas for this action to increase iron uptake in those with anemia.
- Since phenolic groups act as free-radical scavengers and bind to heavy metals, the antioxidant activity of Centaury was studied using an infusion from the flowers. The conclusion was that the phenolic compounds either scavenged the superoxide radicals or noncompetively inhibited xanthine oxidase.
The herb should be taken over several weeks for best effect and should be sipped slowly.
