Key Constituents

Sesquiterpene lactones (absinthin, artabsin)[1, 4]

Intensely bitter sesquiterpene lactones responsible for the classic digestive-bitter action.

Sesquiterpene lactonesSesquiterpenes
Essential oil (thujone, other monoterpenes)[1]

Volatile oil containing thujone (alpha- and beta-isomers), the neurotoxic ketone that limits safe internal use, along with other monoterpenes.

Essential (volatile) oilTerpenes / terpenoids
Flavonoids and phenolic acids[3]

Antioxidant constituents contributing to the plant's antioxidant activity.

Antimicrobial[1, 9, 14, 15]
Antioxidant[1, 3, 5, 6, 10, 14, 15]

Traditional Use & History

Wormwood is one of the classic bitter digestive herbs of European tradition, used to stimulate appetite and bile flow for dyspeptic complaints, and historically as a vermifuge (its common name reflects traditional use against intestinal worms) and in the production of absinthe and vermouth.[1, 4]

Preparations

Infusion[1]

Dried flowering herb infused briefly in hot water as a very bitter digestive tea, taken before meals to stimulate appetite.

Dosage

Short-term use only[14]

Because of its thujone content, traditional herbal references limit internal use to small bitter doses (around 0.5-1 g dried herb per cup) for no more than about 4 weeks at a time. Educational reference only, not a prescription.

Safety, Cautions & Contraindications

Safety note[14, 15]Caution

CAUTION: Contains thujone, which is neurotoxic in significant amounts. Internal use should be limited in duration and dose - short-term use only (under 4 weeks). Contraindicated in pregnancy (powerful uterine stimulant). Avoid in epilepsy, renal disease, and in children. The small amounts present in properly prepared bitter tinctures and vermouth are generally considered safe. The thujone content of absinthe was historically exaggerated.

Safety note[14, 15, 18]Caution

Duke (2002) rates wormwood as + (use with caution) and provides clinical evidence (score 2) for use as an aperitif and bitter digestive tonic, consistent with Commission E approval for dyspeptic complaints and loss of appetite. The plant contains absinthin and artabsin (bitter sesquiterpene lactones) responsible for digestive stimulation, and also thujone - a neurotoxic ketone that is the active agent responsible for 'absinthism' (historical neurological syndrome linked to absinthe consumption). Duke strongly cautions that thujone content limits safe long-term use, and wormwood should not be taken internally for more than 4 weeks at a time. Strictly contraindicated in pregnancy (abortifacient, neurotoxic) and epilepsy (Duke, 2002).
