Feverfew

Feverfew or tanacetum parthenium is a plant historically used as a natural treatment for fever, headaches, itching, migraine prevention, infertility, nausea and vomiting, toothache, inflammation and arthritis.

Migraine prevention
Evidence supporting feverfew supplements for migraine prevention is inconsistent and contradictory. However, a recent clinical trial found that MIG-99, a more stable feverfew extract, appeared to benefit a minority of migraine patients.

Other uses
There is very little evidence for other uses of feverfew.

Risks and safety
Feverfew appears to be probably safe for use in adults who are not pregnant.

Feverfew side effects include:
 * uterine contractions resulting in miscarriage or early labor in pregnancy
 * allergic reactions which may include a skin rash: people allergic to other members of the daisy family (Asteraceae family), including chamomile, chrysanthemums, ragweed and yarrow, should avoid feverfew since they are more likely to be allergic to it
 * heartburn, upset stomach, nausea, vomiting
 * gas, bloating, diarrhea, constipation
 * pounding heartbeats
 * headache, dizziness, feeling nervous;
 * insomnia and feeling tired
