Tanacetum parthenium, known as feverfew,[1] or bachelor buttons,[2] is a flowering plant in the daisy family, Asteraceae. It is a traditional medicinal herb that is used commonly to prevent migraine headaches. Occasionally, it is grown for ornament. It usually is identified in the literature with its synonyms, Chrysanthemum parthenium and Pyrethrum parthenium.

Description[edit]

The plant is a herbaceous perennial that grows into a small bush,[2] up to 70 cm (28 in) high, with pungently-scented leaves. The leaves are light yellowish green, variously pinnatifid. The conspicuous daisy-like flowers are up to 20 mm across, borne in lax corymbs. The outer, ray florets have white ligules and the inner, disc florets are yellow and tubular. It spreads rapidly by seed, and will cover a wide area after a few years.[3][4]

Distribution and cultivation[edit]

Feverfew is native to Eurasia, specifically the Balkan Peninsula, Anatolia, and the Caucasus, but cultivation has spread it around the world and it now is found in the rest of Europe, North America, and Chile.[5]

A perennial herb, it should be planted in full sun, 38 to 46 cm (15–18 in) apart, and cut back to the ground in the autumn. It grows up to 70 cm (28 in) tall. It is hardy to USDA zone 5 (−30 °C (−22 °F)). Outside of its native range, it may become an invasive weed.

Uses[edit]

Leaf of feverfew

In traditional herbal medicine, feverfew has been used for fever, headache, arthritis,[6] and digestive problems.[7][8][9]

The active ingredients in feverfew include parthenolide.[10] There has been some scientific interest in parthenolide, which has been shown to induce apoptosis in some cancer cell lines in vitro and, potentially, to target cancer stem cells.[11][12][13] There are no published in vivo studies of parthenolide or feverfew for humans with cancer.

The parthenolide content of commercially available feverfew supplements varies substantially, by more than 40-fold, despite labeling claims of "standardization". A study found that the parthenolide content of these supplements bore little resemblance to the content claimed on the product labels.[14]

In August of 2019, ScienceDaily reported that researchers at the University of Birmingham announced that they had developed a method to produce parthenolide directly from the plants and a way of modifying that parthenolide to produce a number of compounds, both of which techniques seem promising to enable clinical research into the potential of feverfew for medical applications.[15]

Long-term use of feverfew followed by abrupt discontinuation may induce a withdrawal syndrome featuring rebound headaches and muscle and joint pains.[16] Feverfew may cause allergic reactions, including contact dermatitis.[17] Other side effects have included gastrointestinal upset such as nausea, vomiting, abdominal pain, diarrhea, and flatulence. When the herb is chewed or taken orally it may cause mouth ulcers and swelling and numbness of the mouth.[16] Feverfew should not be taken by pregnant women.[18] It may interact with blood thinners and increase the risk of bleeding, and also may interact with a variety of medications metabolized by the liver.[16]

History[edit]

The word "feverfew" derives from the Latin word febrifugia, meaning "fever reducer",[16] although it no longer is considered useful for that purpose.

Although its earliest medicinal use is unknown, it was documented in the first century (AD) as an anti-inflammatory by the Greek herbalist physician, Dioscorides.[19]
