Feverfew (Tanacetum parthenium) is a traditional European medicinal herb best known for its role in preventing migraines and treating inflammatory conditions. It has been used for centuries for headaches, fevers, and menstrual irregularities. Its main active compounds are parthenolide and other sesquiterpene lactones, which give it anti-inflammatory properties.
1. Migraine Prevention
Feverfew is most famous for reducing the frequency, severity, and duration of migraines.
Works by inhibiting serotonin release, preventing the dilation of blood vessels in the brain, and reducing inflammation.
Most effective when taken daily as a preventative rather than for acute migraine relief.
2. Anti-inflammatory
Reduces production of inflammatory chemicals like prostaglandins and histamine.
Helpful for arthritis, rheumatism, and other inflammatory joint conditions.
Soothes pain and swelling associated with chronic inflammation.
3. Menstrual and Reproductive Health
Traditionally used to help with painful, heavy, or irregular periods.
May ease menstrual cramps through its antispasmodic and anti-inflammatory effects.
4. Fever Reduction (Historical Use)
Its name comes from its traditional use to reduce fevers, though this is less common today.
Historically part of “cooling” remedies in herbal medicine.
5. General Pain Relief
Mildly analgesic and helpful for headaches, neuralgia, toothache, and general aches and pains.
