Feverfew (Tanacetum parthenium) was an important mediaeval herb. It is a bushy perennial with feathery, bright green leaves and small, daisy-like white flowers with yellow centres, similar to chamomile but its flowers are flat-topped.

Its name, feverfew, or ‘fever reducer’ derives from the Latin febrifugia, meaning ‘to put fever to flight’. It was used, as its name suggests, against fevers, but it was also used to treat ‘all hot inflammations’, including arthritis, digestive disorders, and ‘swimming of the head’ (vertigo).

Nicholas Culpeper later famously wrote that the herb was “very effectual for all pains in the head” and its anti-inflammatory properties has earned it the nickname ‘mediaeval aspirin’ in particular due to the compound parthenolide, which was used in teas or chewed fresh, though it has a bitter taste and strong smell.  In fact, its very strong, pungent and bitter scent was used by mediaeval people to purify the air and repel insects like flies and ants.

Protection and Purity: Feverfew was planted near doors of the home to protect against the plague. It was also believed to ward off evil spirits and ‘elf-shot’—sudden sharp pains thought to be caused by invisible fairy arrows.

Women’s Health: In Germany, it was known as Mutterkraut (mother’s herb), used to induce labour, hasten birth, and treat painful menstrual cramps. 

Modern Uses and Precautions

• Migraine Prevention: Today, it’s most recognised for migraine prevention, often in capsule form to avoid side effects. It is currently being researched for potential anti-cancer properties. 
• Side Effects: Can cause mouth sores, swelling, or numbness; avoid if pregnant as it may induce contractions.
• Family: Related to daisies and ragweed; people allergic to these might react to feverfew.
