Key Constituents
Intensely bitter sesquiterpene lactones responsible for the classic digestive-bitter action.
Volatile oil containing thujone (alpha- and beta-isomers), the neurotoxic ketone that limits safe internal use, along with other monoterpenes.
Antioxidant constituents contributing to the plant's antioxidant activity.
Pharmacological Actions
Artemisia absinthium (wormwood) total flavonoids and its constituent alpha/beta-thujone induce ROS- and caspase-mediated apoptosis in cervical and choriocarcinoma cancer cells (preclinical).
Improves glycemic control in type 2 diabetes - lowers fasting blood glucose and HbA1c
Anti-inflammatory and antioxidant; Hepatoprotective / liver support (protects liver cells, antioxidant and antifibrotic)
Digestive support / mild dyspepsia (traditional)
Hepatoprotective / liver support (protects liver cells, antioxidant and antifibrotic); May improve liver enzymes and hepatic fat in non-alcoholic fatty liver disease (NAFLD); Supports liver recovery and 'detox' (traditional framing of the hepatoprotective action)
Traditional & Indicated Uses
inferred from anti-inflammatory action
inferred from antidiabetic action
Artemisia absinthium (wormwood) total flavonoids (cynaroside, astragalin) inhibit HeLa cervical cancer cells via ROS-mediated apoptosis, and its terpenoid alpha,beta-thujone induces caspase-dependent apoptosis in choriocarcinoma cells and sensitizes them to paclitaxel (preclinical).

Safety, Cautions & Contraindications
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.
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).
Very well tolerated, even at high doses; the main effects are mild gastrointestinal upset (nausea, loose stools). As a member of the daisy family (Asteraceae), it can cause allergic reactions in sensitive people.
Has a low potential for drug interactions (little effect on liver CYP enzymes), but use caution with medicines that have a narrow therapeutic window. Human pregnancy data are limited, so use cautiously.

Botanical Description
Aromatic, silvery-grey perennial herb with finely divided, silky-hairy leaves and numerous small, pale yellow, drooping, globe-shaped flower heads borne in loose branched panicles. The whole plant has a characteristic intensely bitter taste and a pungent, sage-like aroma.[4]
Robust biennial (occasionally annual) thistle (Asteraceae), 30-150 cm tall. Leaves are glossy dark green with distinctive white marbled veining (the 'milk' of legend), spiny-margined and deeply lobed. Large, solitary, purple-pink thistle-type flower heads are surrounded by spiny bracts, followed by shiny, mottled brown-black seeds - the part used.[12]
Habitat
Grows on dry, sunny, stony or waste ground, roadsides and field margins; native to Europe, North Africa and temperate Asia, and naturalised in North America.[4]
Native to the Mediterranean region, now naturalised worldwide on disturbed, sunny ground - roadsides, waste places and dry pastures - and widely cultivated commercially for its seed.[12]
Harvesting
The flowering aerial parts (leaf, stem and flower) are cut as flowering begins, in mid- to late summer, and dried in a warm, shaded, airy place.[4]
Seed heads are harvested once fully dry (late summer), and the seeds (fruit) are threshed out.[12]
Traditional Uses
Milk thistle has a very long European folk-medicine tradition, documented since antiquity, as a liver tonic, and its seed extract, standardised to the flavonolignan complex silymarin, is one of the most extensively studied herbal hepatoprotectants. Modern research supports antioxidant, anti-inflammatory and liver-protective activity, with growing interest in metabolic/blood-sugar effects.[12, 13]
Preparations
Dosage
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.
