- Feverfew is native to parts of western Asia and the Balkans, but it now grows throughout the world.
- Feverfew is promoted for fevers, headaches, and arthritis; topically (applied to the skin), it’s promoted for toothache and as an antiseptic and insecticide. Feverfew has been called “medieval aspirin” or “aspirin of the 18th century.”
- Some research suggests that feverfew may help prevent migraine headaches, but results have been mixed. Some research suggests it may reduce migraine headache frequency, as well as some symptoms, such as pain, nausea/vomiting, and light sensitivity.
- There’s not enough evidence to know if feverfew is helpful for other conditions.
- No serious side effects have been reported from feverfew use. Side effects can include nausea, digestive problems, and bloating; if the fresh leaves are chewed, sores and irritation of the mouth may occur.
- People who are sensitive to ragweed and related plants may experience allergic reactions to feverfew.
- Do not take feverfew while pregnant because it may affect uterine contractions. Little is known about whether it’s safe to use feverfew while breastfeeding.
- Using feverfew topically may cause skin irritation.
- Talk to your health care providers about any complementary health approaches before you use. It may be contraindicated with any medications you are currently taking.
