Feverfew is a bushy, aromatic, and perennial herb that typically grows to a height of about 1 to 2 feet (30 to 60 centimeters).  It has bright green, deeply lobed, and serrated leaves, with a strong, bitter odor when crushed.  The plant produces small, daisy-like white flowers with a bright yellow center.  The plant can be grown in any soil, even poor soil, thriving better in semi shade.  
Feverfew has a long history of use in traditional herbal medicine. It was primarily used to treat fevers, migraines, and various ailments related to inflammation and pain. The active compounds in feverfew, called parthenolides, are believed to have anti-inflammatory and vasodilatory properties, which may help relieve migraines and reduce fever. It is sometimes used as a preventive remedy for migraines and tension headaches.  While feverfew is generally considered safe when used in moderate amounts for short periods, it can cause side effects such as mouth ulcers and digestive discomfort in some individuals. Some people may be allergic to it.  If you are considering using feverfew for medicinal purposes, it's advisable to consult with a healthcare professional, especially if you are pregnant, nursing, or taking other medications.
