Editing Willow (section)

==Uses==
The [[Quinault people]] made the bark into a twine which sometimes served as harpoon line. The wood was used by some Native American tribes to [[Friction fire|start fires by friction]], the shoots to [[Basket weaving|weave baskets]], and both the branches and stems to build various items including [[fishing weir]]s.<ref name="Arno-2020" />

The leaves and bark of the willow have been mentioned in ancient texts from [[Assyria]], [[Sumer]] and [[Ancient Egypt|Egypt]]<ref>{{Cite web |date=2015-04-16 |title=Tales and a Tune of the Willow - The Metropolitan Museum of Art |url=https://www.metmuseum.org/perspectives/tales-and-a-tune-of-the-willow |access-date=2025-04-17 |website=www.metmuseum.org |language=en}}</ref><ref name=":0">{{Cite journal |last=Mahdi |first=J.

Interpreting [[Mesopotamia]]n [[cuneiform]] texts is a challenge, especially when looking for something as specific as a species of plant being used to treat a recognisable condition. Some 5,000 medical prescriptions have been identified from Babylonian writings of the 7th to 3rd centuries BC, involving 1,300 drugs from 340 different plants. Whether any of these relate to willow is uncertain.<ref>{{cite web |last1=Boeck |first1=Barbara |title=Investigating the healing arts of Ancient Mesopotamia |url=https://researchoutreach.org/articles/investigating-healing-arts-ancient-mesopotamia/ |website=Research Outreach |date=28 October 2020 |access-date=20 February 2022}}</ref> The seeds of the Haluppu-tree were recommended in the Sumerian narrative of ''[[Epic of Gilgamesh|Gilgameš, Enkidu and the Nether World]]'' as treatment for infertility, but the "Haluppu-tree" could have been oak, poplar or willow.<ref>{{cite web |last1=Boeck |first1=Barbara |title=Proverbs 30:18-19 in the Light of Ancient Mesopotamian Cuneiform Texts |url=https://digital.csic.es/bitstream/10261/20729/1/694.pdf |archive-url=https://ghostarchive.org/archive/20221009/https://digital.csic.es/bitstream/10261/20729/1/694.pdf |archive-date=2022-10-09 |url-status=live |access-date=20 February 2022}}</ref>

The ancient Egyptian [[Ebers Papyrus]] mentions willow (of uncertain species) in three remedies. One, as part of an elaborate recipe for a poultice to "make the ''met'' supple," which involved 36 other ingredients including "fruit of the dompalm, beans and amaa grains." The meaning of ''met'' is uncertain, but it may be something to do with the nervous system. The second is as part of a treatment for the "Great Debility," when "rush from the green willow tree" is combined with ass's semen, fresh bread, herbs of the field, figs, grapes and wine. Finally, it is used as a stiffening agent in a concoction of "fat flesh, figs, dates, incense, garlic and sweet beer" to put the heart into proper working order and make it take up nourishment.<ref>{{cite book |last1=Bryan |first1=Cyril |title=Ancient Egyptian Medicine: the Papyrus Ebers |date=1974 |publisher=Ares Publishing Inc. |location=Chicago |url=https://babel.hathitrust.org/cgi/pt?id=coo.31924073200077&view=1up&seq=5&skin=2021}}</ref>

The Roman author [[Aulus Cornelius Celsus]] only mentions willow once: the leaves, pounded and boiled in vinegar, were to be used as treatment for [[uterine prolapse]], but it is unclear what he considered the therapeutic action to be; it is unlikely to have been pain relief, as he recommended [[cauterization]] in the following paragraph.<ref>''De Medicina'', book VI, p.&nbsp;287, chapter 18, section 10.</ref><ref>{{cite book |last1=Celsus |first1=Aurus Cornelius |title=De Medicina |url=https://penelope.uchicago.edu/Thayer/E/Roman/Texts/Celsus/6*.html |access-date=4 January 2022}}</ref>

[[Nicholas Culpeper]], in ''The Complete Herbal'',<ref>{{cite book |last1=Culpeper |first1=Nicholas |title=The Complete Herbal |date=1653 |location=London |url=https://www.gutenberg.org/files/49513/49513-h/49513-h.htm}}</ref> gives many uses for willow, including to staunch wounds, to "stay the heat of lust" in man or woman, and to provoke urine ("if stopped"), but he makes no mention of any supposed analgesic properties. His recommendation to use the burnt ashes of willow bark, mixed with vinegar, to "take away warts, corns, and superfluous flesh," seems to correspond with modern uses of [[salicylic acid]]. [[William Turner (naturalist)|William Turner]]'s account, written about 1597, focuses on the ability of the leaves and bark to "stay the spitting of blood, and all other fluxes of blood", if boiled in wine and drunk, but adds a treatment for fever, saying: "the green boughs with the leaves may very well be brought into chambers and set about the beds of those that be sick of fevers, for they do mightily cool the heat of the air, which thing is a wonderful refreshing to the sick patients."<ref>{{cite web |last1=Turner |first1=William |title=The Herball, or Generall Historie of Plantes |url=https://www.exclassics.com/herbal/herbalv50587.htm |access-date=8 January 2022}}</ref>

In 1763, Reverend [[Edward Stone (natural philosopher)|Edward Stone]], of Chipping Norton, Oxfordshire, England, sent a letter to the [[Royal Society]] describing his experiments with powdered bark of white willow (''Salix alba'').<ref>{{cite web |last1=Stone |first1=Edward |title=An Account of the Success of the Bark of the Willow in the Cure of Agues |url=https://doi.org/10.1098/rstl.1763.0033 |publisher=The Royal Society |doi=10.1098/rstl.1763.0033 |access-date=5 January 2022}}</ref> He had noticed the willow bark tasted bitter, like 'Peruvian Bark' ([[cinchona]]), which was used to treat fevers, and he speculated that the willow would have a similar effect. Over several years he tested it on as many as fifty patients and found it to be highly effective (especially when mixed with cinchona). Whether this was a real effect or not is unknown, but although Stone's remedy was experimented with by others at the time, it was never adopted by medical practitioners.<ref name=Jeffreys>{{cite book |last1=Jeffreys |first1=Diarmuid |title=Aspirin: the story of a wonder drug |date=2004 |publisher=Bloomsbury |location=London}}</ref> During the [[American Civil War]], Confederate forces also experimented with willow as a cure for malaria, without success.<ref>{{cite journal |last1=Hasegawa |first1=Guy R. |title=Quinine Substitutes in the Confederate Army |journal=Military Medicine |date=2007 |volume=172 |issue=6 |pages=650–655 |doi=10.7205/MILMED.172.6.650 |pmid=17615851 |doi-access=free }}</ref>

In his novel ''[[The Mysterious Island]]'' (1875), the French novelist [[Jules Verne]] outlined the state of scientific knowledge concerning medicinal uses of willow when one of his characters, Herbert (Harbert) Brown, was suffering from a fever induced by a bullet wound: "The bark of the willow has, indeed, been justly considered as a ''succedaneum'' for Peruvian bark, as has also that of the horse-chestnut tree, the leaf of the holly, the snake-root, etc.", he wrote. In the story, Herbert is treated with powdered willow bark to no effect, and is saved when a supply of quinine is discovered.<ref>{{cite book |last1=Verne |first1=Jules |title=The Mysterious Island |date=2010 |publisher=Wordsworth Editions Ltd. |location=Ware |isbn=978-1-84022-624-9 |page=430}}</ref> It is clear in the novel that the causes of fevers were poorly understood, and there is no suggestion at all of any possible analgesic effect from the use of willow.

The first lasting evidence that salicylate, from willow and other plant species, might have real medicinal uses came in 1876, when the Scottish physician [[Thomas John MacLagan|Thomas MacLagan]] experimented with [[salicin]] as a treatment for acute [[rheumatism]], with considerable success, as he reported in ''[[The Lancet]]''.<ref>{{cite journal |last1=MacLagan |first1=T. |title=The treatment of acute rheumatism by salicin |journal=The Lancet |date=28 October 1876 |volume=108 |issue=2774 |page=383 |doi=10.1016/S0140-6736(02)49509-8 |url=https://www.thelancet.com/journals/lancet/article/PIIS0140-6736(02)49509-8/fulltext}}</ref> Meanwhile, German scientists tried salicylic acid in the form of sodium salicylate, a sodium salt, with less success and more severe side effects.<ref>{{cite journal |last1=MacLagan |first1=T. |title=The treatment of acute rheumatism |journal=The Lancet |date=1900 |volume=155 |issue=3998 |page=1904 |doi=10.1016/S0140-6736(01)70583-1 |s2cid=58103130 |url=https://www.sciencedirect.com/science/article/pii/S0140673601705831}}</ref><ref>{{cite journal |last1=Buchanan |first1=W.

The discovery of [[acetanilide]], in the 1880s, gave rise to an 'acetylation' craze, where chemists experimented with adding an acetyl group to various aromatic organic compounds.<ref>{{cite journal |last1=Fürstenwerth |first1=Hauke |title=Letter by Fürstenwerth Regarding Article, "Aspirin: A Historical and Contemporary Therapeutic Overview" |journal=Circulation |year=2011 |volume=124 |issue=12 |pages=e332; author reply e333 |doi=10.1161/CIRCULATIONAHA.111.038133 |pmid=21931098 |doi-access=free }}</ref> Back in 1853, chemist [[Charles Frédéric Gerhardt]] treated the medicine sodium salicylate with [[acetyl chloride]] to produce [[acetylsalicylic acid]] for the first time.<ref name="Jeffreys2008">{{cite book |last=Jeffreys |first=Diarmuid |date=2008  |title=Aspirin the remarkable story of a wonder drug |url=https://books.google.com/books?id=a9gkBwAAQBAJ |archive-url=https://web.archive.org/web/20170908213430/https://books.google.com/books?id=a9gkBwAAQBAJ |archive-date=8 September 2017  |publisher=Bloomsbury Publishing USA |isbn=978-1-59691-816-0 |pages=46–48}}</ref> More than 40 years later in 1897, [[Felix Hoffmann]] created the same acid (in his case derived from the ''[[Spiraea]]'' plant),<ref>{{cite web |last1=Bayer AG |title=All About Aspirin and its History |url=https://www.bayer.com/en/products/aspirin}}</ref> which was found in 1899 to have an [[analgesic]] effect. This acid was named "[[Aspirin]]" by Hoffmann's employer [[Bayer|Bayer AG]]. The discovery of aspirin is therefore only indirectly connected to willow.

In the late 1990s, [[Daniel Moerman]] reported many uses of willow by Native Americans. One modern field guide claims that Native Americans across the Americas relied on the willow as a staple of their medical treatments, using the bark to treat ailments such as sore throat and tuberculosis, and further alleging that "Several references mention chewing willow bark as an analgesic for headache and other pain, apparently presaging the development of aspirin in the late 1800s."<ref name="Arno-2020" />

===Manufacturing===

{{refimprove|date=October 2023}}

[[File:A Modern Cricket Bat.jpg|thumb|[[Cricket bat]]s are traditionally made from willow wood.]]

Some of humans' earliest manufactured items may have been made from willow. A fishing net made from willow dates back to 8300&nbsp;BC.<ref>[https://tuhat.halvi.helsinki.fi/portal/en/publications/the-palaeoenvironme%28878befb8-bd10-4bee-bc01-5038caeadfff%29.html The palaeoenvironment of the Antrea Net Find] The Department of Geography, [[University of Helsinki]]</ref>

Basic crafts, such as baskets, fish traps, wattle [[fence]]s and [[wattle and daub]] house walls, were woven from osiers or [[withies]] (rod-like willow shoots, often grown in [[Pollarding|pollard]]s). One of the forms of Welsh [[coracle]] boat traditionally uses willow in the framework.

Thin or split willow rods can be woven into [[wicker]], which has a long history. The relatively pliable willow is less likely to split while being woven than many other woods, and can be bent around sharp corners in basketry.

Willow wood is used in the manufacture of [[box]]es, [[broom]]s, [[cricket bat]]s, [[cradleboard|cradle boards]], chairmans and other furniture, [[doll]]s, [[willow flute]]s, [[Flagpole (structure)|poles]], [[sweat lodge]]s, toys, turnery, tool handles, [[wood veneer]], [[wand]]s and [[whistle]]s. In addition, [[tannin]], [[fibre]], paper, [[rope]] and string can be produced from the wood.

Willow is used in the manufacture of [[double bass]]es for backs, sides and linings, and in making splines and blocks for bass repair.

=== Horticulture ===
An aqueous extract of willow bark is used as a fungicide in the European Union. The willow bark extract is approved as a 'basic substance' product in the European Union and United Kingdom for the control of scab, leaf peach curl and powdery mildew on grapes, apples and peach crops.<ref>{{Cite web|last=European Commission|title=Review report for the basic substance Salix spp cortex finalised in the Standing Committee on Plants, Animals Food and Feed at its meeting on 29 May 2015 in view of the approval of Salix spp cortex as basic substance in accordance with Regulation (EC) No 1107/2009|url=http://fisportal.mps.hr/download/194-Salix%2520spp.cortex.pdf |archive-url=https://ghostarchive.org/archive/20221009/http://fisportal.mps.hr/download/194-Salix%2520spp.cortex.pdf |archive-date=2022-10-09|url-status=live}}</ref>

===Weeds===
Willow roots spread widely and are very aggressive in seeking out moisture; for this reason, they can become problematic when planted in residential areas, where the roots are notorious for clogging [[French drain]]s, [[Drainage system (agriculture)|drainage systems]], [[weeping tile]]s, [[Onsite sewage facility|septic systems]], [[storm drain]]s, and [[sanitary sewer|sewer systems]], particularly older, [[Pipe (fluid conveyance)#Materials|tile, concrete, or ceramic pipes]]. Newer, [[Plastic pipework|PVC sewer pipes]] are much less leaky at the joints, and are therefore less susceptible to problems from willow roots; the same is true of [[water supply]] piping.<ref>[http://hort.ufl.edu/trees/SALSPPA.pdf Salix spp. UFL/edu], ''Weeping Willow'' Fact Sheet ST-576, Edward F.
