Key Constituents

Sesquiterpenes (petasin and isopetasin)[2, 5, 7, 9, 10, 11]

The anti-inflammatory and antispasmodic active principles; standardised in commercial extracts.

Sesquiterpenes
Pyrrolizidine alkaloids (PAs)[11]

Naturally present but hepatotoxic and carcinogenic; must be removed to make a safe product.

Alkaloids
Sesquiterpene lactones (parthenolide)[8, 9, 11, 12, 13]

Parthenolide is the principal active compound, to which extracts are often standardised; it is biosynthesised and stored in the glandular trichomes of the aerial parts.

Safety, Cautions & Contraindications

Safety note[11]Serious

Use ONLY certified pyrrolizidine-alkaloid (PA)-free, standardised extracts. Raw or unprocessed butterbur contains PAs that are toxic to the liver and potentially carcinogenic.

Safety note[11]Caution

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.

Safety note[11]Info

As a member of the daisy family (Asteraceae), it can cause allergic reactions in people sensitive to ragweed and related plants. Chewing fresh leaves commonly causes mouth ulcers and oral soreness.

Safety note[11]Caution

Stopping feverfew abruptly after prolonged use can cause a 'post-feverfew' rebound of headache, anxiety and muscle/joint stiffness. Avoid in pregnancy (uterine-stimulant) and breastfeeding, and use caution with anticoagulant/antiplatelet medicines.

Botanical Description

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]

Height: Flower spikes low in early spring; leaves later up to ~1 m across
Habit: Robust, rhizomatous, colony-forming perennial herb
Leaves: Enormous, rounded to heart-shaped, up to ~1 m across, on stout stalks
Flowers: Thick, pinkish, scaly flower spikes, appearing before the leaves
Stem: Thick underground rhizome; scaly flowering stalks in early spring
Root: Thick, spreading rhizome
Fruit: Small ribbed achenes with a pappus (typical Asteraceae)
Flowering Period: February-April, before the leaves emerge

Aromatic perennial herb (Asteraceae), 20-60 cm tall, with much-branched, downy stems. Leaves are yellow-green, bipinnately divided and strongly scented. Small, daisy-like flower heads have white ray florets and a flat yellow disc, borne in loose clusters.[13]

Height: 20-60 cm
Habit: Erect, much-branched, aromatic perennial herb
Leaves: Yellow-green, bipinnately divided, strongly scented
Flowers: Small, daisy-like, white ray florets around a flat yellow disc
Stem: Much-branched, downy
Root: Fibrous perennial rootstock
Fruit: Small ribbed achenes (typical Asteraceae)
Flowering Period: June-September

Habitat

Native to damp, marshy ground across Europe and western Asia - riverbanks, ditches, wet meadows and damp woodland margins - favouring moist, nutrient-rich soils.[2]

Native to the Balkans and Caucasus region, now naturalised across Europe, North America and elsewhere; grows on disturbed ground, walls, roadsides and waste places, and is widely cultivated.[11]

Harvesting

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]

Parts: Root/rhizome, Leaf
Season: Root/rhizome in autumn or early spring; leaf during the growing season

Leaves (aerial parts) are gathered during the growing season, ideally at flowering, and dried or used fresh.[13]

Parts: Leaf (aerial parts)
Season: Growing season, ideally at flowering

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]

Feverfew has a long European folk tradition, its name derived from 'febrifuge' (fever-reducer), as a remedy for fevers, headaches and joint pain. Modern use and clinical research focus on migraine prevention, with parthenolide identified as the key active compound responsible for inhibiting the inflammatory pathways implicated in migraine.[11]

Preparations

Standardised PA-free extract (tablet)[3, 4, 11]

The only recommended form - e.g. the CO2-extracted root product studied for migraine prevention, or the Ze 339 leaf extract studied for allergic rhinitis. Raw root or leaf tea should never be used, as it retains hepatotoxic pyrrolizidine alkaloids.

Standardised leaf extract (capsule)[11]

Freeze-dried or standardised-parthenolide extract, the form used in most clinical trials.

Dosage

Standardised PA-free extract[3, 4]

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.

Standardised extract[11, 12]

Clinical trials for migraine prevention have most often used standardised extracts providing around 0.2-0.6% parthenolide, taken daily; do not stop abruptly after prolonged use given a documented 'post-feverfew' rebound syndrome. Educational reference only, not a prescription; avoid in pregnancy and with anticoagulants.

Dangerous Lookalikes

Safety note[14]Dangerous
Dangerous Plant: adenostyles-alliariae
Confused Part: Very large rounded leaves and rhizome gathered for use; alpendost has similar large rounded leaves and the same hepatotoxic pyrrolizidine alkaloids.
Confusion Context: Butterbur (Petasites hybridus) has very large rounded leaves and is used medicinally (as pyrrolizidine-free standardised extracts). In the wild its foliage is confused with alpendost (Adenostyles alliariae) and coltsfoot, all large-leaved damp-ground plants. Alpendost contains hepatotoxic pyrrolizidine alkaloids and, gathered in mistake for coltsfoot/butterbur and brewed as tea, has caused liver veno-occlusive disease (Sperl et al., 1995). Butterbur's own raw leaves also contain pyrrolizidine alkaloids, so wild butterbur should only be used as tested, PA-free products rather than home-gathered material.
Distinguishing Features: Leaf: butterbur has enormous rounded leaves (up to about 1 m across when mature) on stout stalks; alpendost leaves are large but smaller and more coarsely toothed. Neither should be brewed from home-gathered material., Flowers: butterbur pushes up thick pinkish flower spikes in early spring before the leaves; alpendost has fluffy whitish-pink flower clusters among its leaves in summer., Best practice: do not brew wild butterbur or its large-leaved lookalikes at all - use only standardised, pyrrolizidine-free commercial butterbur preparations.
Key Test: Do not gather large rounded 'butterbur' leaves for tea - butterbur, alpendost and coltsfoot all look alike and carry liver-damaging pyrrolizidine alkaloids. Use only standardised, pyrrolizidine-free commercial butterbur products rather than home-collected leaves.

Drug Class Interactions

Safety note[14]Caution
Drug Class: anticoagulants-antiplatelets
Mechanism: Feverfew and its component parthenolide inhibit platelet aggregation and serotonin release, so combining it with anticoagulant or antiplatelet drugs may increase bleeding risk.

Pairings

Not documented

Feverfew and ginger both reduce blood clotting/platelet stickiness, so taking them together may add up and raise the risk of bruising or bleeding — use caution, especially before surgery or alongside blood-thinning drugs.[14, 15, 16]
