Feverfew

Tanacetum parthenium

Also calledMutterkraut (German) · Matricaria / Hierba de Santa María (Spanish) · Grande camomille (French) · Bachelor's buttons (English) · Xiǎo bái jú 小白菊 (Chinese)

A bitter, strongly scented little daisy whose name is a corruption of 'febrifuge'. Today it is best known as a herbal migraine preventative.

Tanacetum parthenium, known as feverfew, is a flowering plant in the daisy family, Asteraceae. It may be grown as an ornament, and may be identified by its synonyms, Chrysanthemum parthenium and Pyrethrum parthenium. Having its origin in the Balkans region, it is now distributed worldwide.

§1

What it can do

  1. iLeaves contain parthenolide, a sesquiterpene lactone that blocks NF-κB inflammatory signalling in lab studies
  2. iiPungent camphor-scented foliage repels many insects
  3. iiiSelf-seeds freely into wall crevices and paving

Edible
Edible with care

Toxic
Deadly

Very bitter; chewing fresh leaves causes mouth ulcers in some people.

§3

In the medicine cabinet

TraditionUse
European folk medicineLeaves eaten in bread or as tea for headache, fevers, arthritis and to bring on menstruation
Modern phytotherapyDried leaf or CO2 extract to prevent migraine attacks; EMA traditional-use monograph
Latin American folk medicineInfusions used in Mexico and Central America for colic, stomach ache and menstrual pain

Weight of evidence

Moderate. Some clinical trials with promising but limited or mixed results.

Active compounds

parthenolide, camphor, chrysanthenyl acetate, tanetin, apigenin

CautionTrials for migraine prevention are mixed; a Cochrane review found any benefit small and uncertain. Causes mouth ulcers and digestive upset, and stopping suddenly may cause rebound headaches ('post-feverfew syndrome'). Avoid in pregnancy because it stimulates the uterus, and with anticoagulants or Asteraceae allergy.

§9

Marginalia

Dioscorides recommended parthenion, a name later linked to the Parthenon. The modern migraine interest began in the 1970s with Welsh patients' reports and led to a 1985 trial at the London Migraine Clinic published in the BMJ.

Curiosity

'Feverfew' comes from the Latin febrifugia, 'fever-chaser', although the plant does little to lower fevers.
