Description
Elecampane is a rather rigid herb, the stem of which attains a height of about {{convert|90-150|cm|abbr=on}}. The leaves are large and toothed, the lower ones stalked, the rest embracing the stem; blades egg-shaped, elliptical, or lance-shaped, as big as {{convert|30|cm|abbr=on}} long and {{convert|12|cm|abbr=on}} wide. Leaves are green on the upper side with light, scattered hairs, but whitish on the underside because of a thick layer of wool. The flower heads up to 5 cm (2 inches) broad, each head containing 50-100 yellow ray flowers and 100-250 yellow disc flowers. The root is thick, branching and mucilaginous, and has a bitter taste and a camphoraceous odour with sweet floral (similar to violet) undertones.
Folklore
The plant's specific name, helenium, derives from Helen of Troy; elecampane is said to have sprung up from where her tears fell. It was sacred to the ancient Celts, and once had the name "elfwort".{{cite book

The 17th-century herbalist Nicholas Culpeper considered elecampane to be ruled by Mercury and used it to warm a cold and windy stomach, to resist poison, to strengthen sight, and to clear internal blockages.{{cite book |last1=Culpeper |first1=Nicholas |title=Culpeper's Complete Herbal |date=1814 |publisher=Richard Evans |location=No. 8, White's Row, Spitalfields |pages=70}}
Uses
The herb has been used since Ancient Greek times. Theophrastus recommended using the plant in oil and wine to treat the bites of vipers, spiders and pine caterpillars in his Historia Plantarum.{{cite book |last=Roques |first=Alain |title=Processionary moths and climate change : an update |publisher=Springer |publication-place=Dordrecht |year=2015 |isbn=978-94-017-9339-1 |oclc=893559920 |page=1}}
In Roman times, Apicius, a cookbook from the 1st century AD, describes it as a plant for testing whether honey is spoilt or not, the plant is immersed in the honey and then lit, if it burns brightly the honey is considered fine.{{Cite book|title=De Re Coquinaria of Apicius|url=https://penelope.uchicago.edu/Thayer/E/Roman/Texts/Apicius/1*.html#9note5|pages=Book I, 18}} The root was mentioned by Pliny in his Natural History both as a medicine and as a condiment.
In Medieval Europe, the roots were candied and eaten as confectionery.{{cite book |editor1-last=Prance |editor1-first=Ghillean |editor2-last=Nesbitt |editor2-first=Mark |last1=Sanderson |first1=Helen |last2=Renfrew |first2=Jane M. |date=2005 |title=The Cultural History of Plants |publisher=Routledge |page=102 |isbn=0415927463}}
In France and Switzerland it has been used in the manufacture of absinthe.{{EB1911|inline=y|wstitle=Elecampane|volume=9|page=169}} In England it was formerly in great repute as an aromatic tonic and stimulant of the secretory organs. It is mentioned in an 1817 New-England almanack as a cure for hydrophobia when the root is bruised and used with a strong decoction of milk.{{Cite book | author = Daboll, N. | date = 1816 | title = The New-England almanack, for the year of our Lord Christ, 1817: Fitted to the meridian of N.

Chemical constituents
Besides the storage polysaccharide inulin (C6H12O6[C6H10O5]n), a polymer of fructose, the root contains helenin (C15H20O2), a phytochemical compound consisting of alantolactone and isoalantolactone. Helenin is a stearoptene, which may be prepared in white acicular crystals, insoluble in water, but freely soluble in alcohol. When freed from the accompanying inula-camphor by repeated crystallization from alcohol, helenin melts at 110 °C.
