Characters of herbs: Feverfew leaves are the leaves of Tanacetum parthenium. The plant is cut before full flowering. It is dried in thin layers in the shade, at temperatures not exceeding 35 °C (Celsius, or 95 degrees Fahrenheit).
Related studies found that taken on a regular basis, small amounts of dried leaves can help reduce the frequency, severity, and symptoms such as nausea and vomiting associated with migraine headaches. But feverfew has no impact on migraine headaches. Its component sesquiterpene lactone inhibit the release of serotonin antagonists from blood platelets, serotonin antagonists released during an attack may contribute to migraine pain by constricting blood vessels, and some sesquiterpene lactones also have antispasmodic activity, parthenolide may lower the pain threshold. Common tension headaches differ from migraine headaches in several ways, feverfew probably works only for migraine headaches. The herb has an anti-inflammatory effect, decreases platelet aggregation, antispasmodic effect, parthenolide and similar lactones are cytotoxic to several human cancer cell lines.
