Eupatorium is a

Mithridates Eupator, king of Pontus.[3]

Systematics and taxonomy

Eupatorium has at times been held to contain as many as 800 species,[4] but many of these have been moved (at least by some authors) to other genera, including Ageratina, Chromolaena, Condylidium, Conoclinium, Critonia, Cronquistianthus, Eutrochium, Fleischmannia, Flyriella, Hebeclinium, Koanophyllon, Mikania, and Tamaulipa.[5]

The classification of the tribe Eupatorieae, including species placed in Eupatorium in the present or past, is an area of ongoing research, so further changes are likely. What seems fairly certain by now is that there is a monophyletic group containing Eupatorium (about 42 species of white flowered plants in North America, Europe and Asia, but not South America) and the Joe-pye weeds (Eutrochium), and possibly others.[6][7]

Uses

Eupatorium are grown as ornamental plants, particularly in Asia.[8] A number of popular ornamental plants formerly included in Eupatorium have been moved to other genera, such as Bartlettina and Conoclinium.

Tobacco leaf curl virus is a pathogen occasionally affecting plants of this genus. The foliage is eaten by some Lepidoptera larvae, including those of Orthonama obstipata (The Gem).

Medical use

The common names for the plants are all based on the previous usage of one species, Eupatorium perfoliatum, as an herbal medicine. Despite its name, boneset is not used to treat broken bones,[9][unreliable source?] instead the common name apparently derives from the herb's use to treat dengue fever, which was also called breakbone fever because of the pain that it caused. The name thoroughwort also comes from Eupatorium perfoliatum, and refers to the perfoliate leaves, in which the stem appears to pierce the leaf (i.e. go through, note that in older usage "thorough" was not distinguished from "through", compare for example the word thoroughfare).

Boneset, although

folk medicine,[10] for instance to excrete excess uric acid which causes gout
. Caution is advised when using boneset, since it contains
toxic compounds that can cause liver damage.[citation needed] Side effects include muscular tremors, weakness, and constipation
; overdoses may be deadly.
