Feverfew is related to the daisy. It grows throughout the U.S. and Europe. It’s been
used as a pain reliever for centuries.
Its feathery, aromatic leaves are used to prevent migraine headaches. Experts say
that parthenolide and other ingredients in feverfew get in the way of serotonin and
prostaglandin. These are natural substances that dilate the blood vessels. They may
be responsible for triggering migraines.
Feverfew is likely to work for migraines if taken daily for at least several months.
It’s important to note that it prevents migraines. It doesn’t treat them. This means
that it won’t help if you take it when you have a migraine.
Feverfew's main active part is the sesquiterpene lactone, parthenolide. It works to
reduce the chance of migraines through physiological pathways.
Medically valid uses
Studies suggest that feverfew decreases the severity and frequency of migraines. However,
results are mixed. More research is needed to know if this is true.
There may be benefits that haven't yet been proven through research.
Feverfew may ease nausea and vomiting due to migraines. It may take a month or longer
for it to work.
Feverfew may reduce painful inflammation due to arthritis.
Feverfew may help bring on uterine contractions to reduce the length of labor. It
may aid in starting menstrual periods and treating menstrual pain.
Feverfew may relieve colitis and soothe insect bites. It may boost appetite by acting
as a digestive bitter. It tastes bitter and helps the digestive process to work better.
Feverfew is available in oral tablets, capsules, liquid extract, and teas. Follow
the instructions on the package for the correct dose.
Side effects, toxicity, and interactions
Fresh leaves may cause mouth ulcers (aphthous ulcers) in some people. People with
allergies, especially to ragweed, may be sensitive to it. This is because it’s a member
of the same plant family.
Women who are pregnant or breastfeeding should not use feverfew.
People who stop taking feverfew after using it for a long time may have withdrawal
side effects. These include headaches, trouble sleeping, anxiety, and stiff muscles.
