Talk:Arctium

Diction
It's confusing to say this is "native to the Old World." It would be clearer to say which specific areas it was native to and when. — Preceding unsigned comment added by Prell (talk • contribs) 13:45, 23 September 2015 (UTC)

Gobou
I redirected Gobou to this page because, so far as I can tell, it's just the Japanese word for the same plant. A better botanist than I might have something clearer to say on the subject.
 * Arctium lappa is defined as Gobo in Japanese page as well, so I think it is alright. Revth 15:02, 4 Oct 2004 (UTC)

usage in Canadian Maritimes
I had been led to believe the word "Burdock" was unique the Maritime provinces of New Brunswick, Nova Scotia and PEI.

Canadians in other provinces call them "Burrs".

Picture
There's a good free picture from the Probert Encyclopaedia located here.

Odd trait
Burdock is able to produce stems, flowers, and seeds after its foliage has been killed by a defoliant. PixOnTrax 06:50, 17 February 2007 (UTC)
 * This plant is located about six feet (2 m) away from railroad tracks. Workers sprayed a defoliant along the railroad's right-of-way to keep it free of weeds and young trees.  PixOnTrax 07:10, 17 February 2007 (UTC)


 * This photograph was made about 3 months after the defoliant had been applied to the plant. PixOnTrax 07:20, 17 February 2007 (UTC)


 * Had the plant not been defoliated it would have produced about 10 times more seeds than those shown in the photograph. Setting flowers and producing seeds after the foliage has been killed is an odd trait possessed by burdock. PixOnTrax 07:40, 17 February 2007 (UTC)

It is not so odd. Most plants - as long as the root is alive and contains enough nutrients to start to regrow the plant will behave in a similar way. Dandelions are notoriously difficult to eradicate from a lawn because of the deep root and the plant regrowing from it. i have seen trees cut down and next thing from the side of the trunk left above the ground start a dozen of sprouting saplings.80.99.38.199 (talk) 08:00, 1 October 2017 (UTC).

Safety
Under sction safety we have this:

Do not gather burdock in the wild unless you know what you are doing.

What is the problem with wild Burdock roots? Is this even true? —Preceding unsigned comment added by 130.89.166.51 (talk) 14:45, August 26, 2007 (UTC)

Move "Greater burdock" stuff to its article
Since this article has evolved into a general overview of the Arctium genus, most of the information that is specific to the Greater burdock (Japanese gobo), such as culinary uses, should be moved to that article. --Jorge Stolfi (talk) 18:34, 10 May 2009 (UTC)
 * Agree, but I am removing the merger templates because there should not be just one article. Nadiatalent (talk) 13:17, 10 December 2011 (UTC)

Copyright violation
I removed text that was copy and pasted from the University of Maryland Medical Center. The text that was copied is part of the first paragraph under the Overview section. -- Joel M.  Chat ✐  18:53, 21 September 2010 (UTC)


 * That may well have been taken from Wikipedia originally. The safety section (which I just removed) was, in an earlier version, verbatim with text on the UMMC website. I'd be willing to add the safety section back if I was sure I could cite UMMC as the original source, but I'm very skeptical of the claim that Atropa is uniquely likely to be confused with burdock, and am more inclined to think it originated in Wikipedia than UMMC. Copyvio's can go both ways; Wikipedia is often copied these days.Plantdrew (talk) 00:16, 31 October 2012 (UTC)

Removing Safety section
I'm removing the Safety section, which reads:

"Because the roots of burdock resemble those of deadly nightshade (also known as belladonna or Atropa belladonna), which is extremely poisonous, it is sometimes cautioned as a safety risk. Given that the plants above ground are readily distinguishable, and chiefly because their habitats rarely overlap, it is unlikely that the toxic plant's root should be found beneath the foliage of the edible one's. However, positive identification is a necessary precondition to the consumption of any wild plant."

Accidentally getting the roots of the wrong plant is certainly a risk when harvesting roots. Lots of roots look alike, but there is no reason to think (and no reference to support) Atropa roots (specifically) being often confused with burdock. This looks like a piece of Wikilore that escaped into the wild; I can't find any mention of belladonna being confused with burdock when doing a blog search on Google prior to 2007 (when the safety section was added), but it's all over the blogosphere now. I did find anecdotes about Datura poisonings when people thought they were consuming burdock, and am wondering if a garbled version of one of those poisonings is the source of the apparent myth (Datura is in the deadly nightshade family).Plantdrew (talk) 23:59, 30 October 2012 (UTC)

Traditional use section
"is used in Europe as a scalp treatment.[citation needed]" - i am not sure, how one gets a scientifically trustworthy 2nd or 3rd level source to prove that there is an oil in commercial sale that is said to contain arctium/burdock extract and is supposed to be put on peoples heads, but searching for "kletten wurzel haar öl" produced quite a few hits and klettenwurzel seems to be the german name for arctium/burdock extract.80.99.38.199 (talk) 08:24, 1 October 2017 (UTC).
