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 agents that dilate the blood vessels. They may be responsible for triggering migraines.
Feverfew is likely only to work for migraines if you take it each day for a long time. 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.
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.
Please note that this section reports on claims that have not yet been substantiated through studies.
Feverfew may also ease nausea and vomiting due to migraines. It may take a month or longer for it to work.
Feverfew is said to reduce painful inflammation due to arthritis. But one study showed that it didn’t help women who had not responded to arthritis medicines. People have also used it to decrease the thickness of secretions in the lungs. It may also treat dizziness and tinnitus.
Feverfew may also help bring on uterine contractions to reduce the length of labor. It may also aid in starting menstrual periods and treating menstrual pain.
Feverfew has also been claimed to relieve colitis and soothe insect bites. It may also boost appetite by acting as a digestive bitter. It tastes bitter and helps the digestive process to work better.
