Feverfew – tanacetum parthenium. Traditionally, as its name suggests, this herb has been used to reduce fevers. One of the most common applications of feverfew is in reducing the severity and frequency of migraine headaches. The effects appear to be due to its ability to improve blood vessel function, correct platelet abnormalities and reduce inflammatory response. Feverfew is also used for swelling and pain from arthritis.
