Some research suggests that feverfew may help to prevent migraine headaches, but results have been mixed. However, evidence-based guidelines from the American Academy of Neurology and the American Headache Society suggest that a feverfew extract may be effective and should be considered for migraine prevention.

There’s not enough evidence to know if it helps other conditions.

Side Effects Of Feverfew

No serious side effects have been reported. 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 take it for a long time and then stop taking it may have difficulty sleeping, headaches, anxiety, and stiff and painful muscles.

Do not take feverfew while pregnant, because it may affect uterine contractions.

Handling the plant may cause skin irritation.
