Feverfew | Uses, Properties, and Preparations
Feverfew (Tanacetum parthenium) monograph
Family: Asteraceae
Native Range & Cultivation: Feverfew is native to southeastern Europe and western Asia and has been cultivated and naturalized throughout Europe, North America, and other temperate regions. It grows readily in gardens, roadsides, and disturbed soils, favoring full sun and well-drained ground. Historically, feverfew was commonly planted near homes for ready access as a household remedy.
Common Medicinal Properties: Anti-inflammatory, Antispasmodic, Bitter, Carminative, Emmenagogue, Nervine, Tonic (circulatory)
Contraindications: Feverfew should not be used during pregnancy due to its emmenagogue action. Use caution in individuals taking anticoagulant or antiplatelet medications, as feverfew may influence platelet aggregation. Abrupt discontinuation after long-term use may result in rebound headaches in some individuals. Fresh leaf use may cause mouth irritation or ulceration. Avoid use in individuals with known sensitivity to plants in the Asteraceae family.
Parts Used: Leaves and flowering tops (aerial parts).
Preparation & Forms: Traditionally used fresh or dried as an infusion, tincture, or chewed leaf. Modern use most commonly involves standardized extracts or encapsulated preparations. Feverfew is often taken regularly over time rather than acutely, particularly in traditions addressing recurrent patterns rather than immediate symptoms.
Key Constituents: Sesquiterpene lactones (notably parthenolide), flavonoids, volatile oils, tannins; trace bitters.
Folk Use & Lore: Feverfew has a long reputation as a plant of prevention rather than crisis. Traditionally associated with easing headaches, fevers, and inflammatory discomfort, it was often taken routinely to reduce the frequency or severity of recurring complaints. In folk practice, feverfew was considered a “steadying” herb — one that addressed underlying patterns rather than dramatic flare-ups.
Energetics: Traditionally considered cooling, drying, and dispersing; associated with reducing excess heat, calming inflammatory processes, and easing tension linked to circulatory or nervous stagnation.
Current Research: Current research on Tanacetum parthenium has focused primarily on its role in migraine prevention and inflammatory modulation. Clinical studies suggest that standardized feverfew preparations may reduce the frequency and intensity of migraine headaches in some individuals, likely through the activity of parthenolide on inflammatory pathways and platelet aggregation. Results across studies have been mixed, reflecting differences in preparation, dosage, and study design. While evidence supports feverfew’s traditional use in headache prevention, further research is needed to clarify optimal formulations and long-term safety.
