''Eupatorium perfoliatum'' or (Common) Boneset is a common North American perennial plant in the sunflower family. It is native to the Eastern United States and Canada, widespread from Nova Scotia to Florida, west as far as Texas, Nebraska, the Dakotas, and Manitoba.〔(【引用サイトリンク】 Eupatorium perfoliatum )〕〔(Biota of North America Program 2014 county distribution map )〕 It is also called "agueweed", "feverwort" or "sweating-plant". It was introduced to American colonists by Indians who used the plant for breaking fevers by means of heavy sweating. It is nearly always found in low, wet areas and is often found near ''Phalaris arundinacea'' (Reed canary grass). ==Description==
''Eupatorium perfoliatum'' grows up to 100 cm (40 inches) tall, with leaves that clasp the stems. The plant produces and dense clusters of tiny white flower heads held above the foliage. The leaves growing together around the stem lead to a past superstition that wrapping the leaves in bandages around splints would help mend broken bones.〔Audubon Society Field Guide To Wild Flowers - Eastern Region - 1979〕 Boneset also had other medical uses,〔 and was a very common remedy in the United States in the 19th century. The common name boneset apparently derives from the plant's historical use in treating dengue fever (which is also known as breakbone). ''Eupatorium perfoliatum'' can form hybrids with other species of the genus ''Eupatorium'', for example ''Eupatorium serotinum''.〔
