Ague weed, also known as feverfew, is a medicinal plant that has been traditionally used to treat fevers and migraines. The word ague is pronounced /eɪɡjuː/ with the 'a' sounding like 'aye' and the 'g' and 'u' blending together to create a hard 'g' sound. The word weed is pronounced /wiːd/ with a long 'e' sound and a silent 'd'. The spelling of ague weed may seem confusing due to the silent 'ue' at the end of ague, but it is simply a remnant from the Middle English spelling of the word.
Ague weed, also known as feverweed or thoroughwort, is a perennial herbaceous plant belonging to the genus Eupatorium, specifically the species Eupatorium perfoliatum. It is native to North America and can be found growing in wetland areas, such as swamps, marshes, and damp meadows.
The term "ague" in ague weed refers to a type of intermittent fever, often associated with chills and shivering, which was common in the past. This plant was traditionally used in folk medicine to treat such feverish symptoms, thus earning its name.
Ague weed typically grows up to 5 feet (1.5 meters) in height and features broad, lance-shaped leaves that are arranged oppositely along the stem. The stem appears to perforate the leaves, hence the species name "perfoliatum." In late summer or early fall, it produces clusters of small, whitish or pale purple flowers, attracting various pollinators like bees and butterflies.
In addition to its historical medicinal uses, ague weed also serves as a food source for several insect species. Moreover, its dense foliage and tall height make it a valuable plant for erosion control and as a natural filter for water purification.
While regarded as an attractive plant in landscaping due to its showy flowers and ability to attract wildlife, it is important to note that ague weed can be invasive in some regions. Therefore, it is necessary to consider its potential impact on native flora before introducing it into a new area.
The word "ague" comes from the Middle English term "ague" or "agueweede", which was derived from the Old English "ague". In turn, "ague" originated from the Latin word "acuta" meaning "acute" or "sharp".
The term "ague" refers to a fever, specifically one with recurring periods of chills and fever. "Ague weed" is a plant believed to have medicinal properties for treating such fevers.
