Evidence face-off — shared uses
| Condition | Wormwood | Butterbur | Verdict |
|---|---|---|---|
| Cancer (anticancer research) | 2/10 | 2/10 | Comparable evidence |

Evidence scores (1–10) are computed from the tier of each cited source. “Comparable” means the two scores are within one point. Follow a score to its detailed sources.
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.
The anti-inflammatory and antispasmodic active principles; standardised in commercial extracts.
Naturally present but hepatotoxic and carcinogenic; must be removed to make a safe product.
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).
Relief of allergic rhinitis / hay fever (antihistaminic and leukotriene-inhibiting; systematic review found it superior to placebo and comparable to non-sedating antihistamines for intermittent allergic rhinitis)
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).

Migraine prophylaxis (reduces attack frequency; up to ~60% reduction vs placebo in a randomised controlled trial of a standardised CO2 root extract)
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).
Use ONLY certified pyrrolizidine-alkaloid (PA)-free, standardised extracts. Raw or unprocessed butterbur contains PAs that are toxic to the liver and potentially carcinogenic.
Avoid during pregnancy and breastfeeding. As a member of the daisy family (Asteraceae), it can cause allergic reactions in people sensitive to ragweed and related plants. Watch for and report any signs of liver problems.

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, rhizomatous perennial herb (Asteraceae) that flowers before the leaves emerge: thick, pinkish, scaly flower spikes push up from the ground in early spring, followed by enormous rounded to heart-shaped leaves - up to about 1 m across at maturity - on stout stalks, giving rise to the common name 'umbrella plant'.[2]
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 damp, marshy ground across Europe and western Asia - riverbanks, ditches, wet meadows and damp woodland margins - favouring moist, nutrient-rich soils.[2]
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]
Rhizome/root is dug in autumn or early spring; leaves are gathered during the growing season. Raw material naturally contains hepatotoxic pyrrolizidine alkaloids, so commercial products are manufactured to remove them (PA-free standardised extracts); home-gathered material should never be used medicinally.[11]
Traditional Uses
Butterbur has a long European folk-medicine history as a fever remedy - the name 'pestilence wort' reflects its historic use during plague outbreaks - and for asthma, cough and migraine-type headache. Modern clinical trials of standardised, pyrrolizidine-alkaloid-free extracts support its use for migraine prevention and allergic rhinitis.[2, 3, 4]
Preparations
Dried flowering herb infused briefly in hot water as a very bitter digestive tea, taken before meals to stimulate appetite.
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.
Clinical trials have used standardised PA-free extracts (for example around 50-75 mg twice daily of a CO2 root extract for migraine prevention). Always use a certified PA-free commercial product, never raw plant material. Educational reference only, not a prescription.
