Feverfew is a perennial herb native to the Balkan Peninsula that has spread across Europe and the Americas. Its name comes from the Latin 'febrifuga,' meaning fever reducer, though modern research has focused primarily on its role in migraine prevention. The plant has been used medicinally for over 2,000 years, appearing in early Greek texts and later becoming a staple of British herbal apothecaries.

Feverfew's primary active compound, parthenolide, inhibits the release of serotonin from blood platelets and blocks certain inflammatory signaling molecules — both of which play a role in triggering migraines. It also reduces the production of prostaglandins, the chemicals that drive pain and inflammation throughout the body. This combination of platelet, serotonin, and inflammation modulation is what makes it useful for both headache prevention and general inflammatory discomfort.

Dried leaf capsules and standardized extracts are the most practical and consistent forms for therapeutic use. Tinctures are available but alcohol extraction can reduce parthenolide content. Chewing raw leaves was the traditional British folk remedy but commonly causes mouth ulcers and is generally not recommended. Tea is mild and often below therapeutic parthenolide levels.

• Migraine prevention
• Migraine frequency and severity
• Tension headaches
• Inflammatory pain
• Arthritis and joint pain
• Menstrual cramps and pain
• Fever management
• Anxiety and mild mood support
• Skin inflammation and psoriasis

• Migraine attacks — daily use reduces frequency in migraine-prone individuals
• Medication overuse headache — by reducing migraine frequency, may lower reliance on acute pain medications

Feverfew is an isolated herb and is not meaningfully present in common foods. To support the same pathways — reducing inflammatory triggers and supporting healthy circulation — focus on anti-inflammatory foods like fatty fish (salmon, mackerel), leafy greens (spinach, kale), olive oil, turmeric, ginger, and magnesium-rich foods like pumpkin seeds and dark chocolate. Magnesium in particular is closely linked to migraine prevention and works well alongside feverfew. Limit processed foods, alcohol, and tyramine-rich foods like aged cheeses and cured meats, which are common migraine triggers.

• Mouth ulcers and inflammation (mainly with raw leaf chewing)
• Stomach upset, nausea, or bloating
• Post-feverfew syndrome — rebound headaches, anxiety, and muscle stiffness when stopping abruptly after long-term use
• Skin rash or contact dermatitis (especially with topical use)
• Mild dizziness
• Increased heart rate (rare)

• Recommended daily: 50–150 mg of dried leaf extract standardized to 0.2–0.7% parthenolide, taken once daily; some protocols use up to 300 mg/day split into two doses
• Best time of day: Morning is most common, though timing is flexible — consistency matters more than clock time
• With or without food: Take with food to reduce the chance of stomach upset
• Time to effect: Allow 4–12 weeks of consistent daily use before evaluating results for migraine prevention
• How long to take it: Appropriate for ongoing daily use for migraine prevention; if discontinuing after long-term use, taper gradually over 2–4 weeks to avoid rebound headache syndrome
