it seems someone (69.155.13.227) has sabotaged the page, restored it to older version. -- 140.116.90.9 07:23, 31 Jan 2005 (UTC)
From the article: "Tincture of iodine is recently available as a solution of complex of iodine with polyvinylpyrrolidone. This mixture is known under trade name Betadine."
I'll work on this when I have time. Maybe it would be best to link to
Betadine in a 'see also' section so that the information is not completely removed from this article.

Removal of a dubious paragraph from the main page and paste hereafter:
It can also be used to detect and treat iodine deficiency which can lead to hypothyroidism<ref name=deficiency>{{cite web|url=http://wonder.cdc.gov/wonder/prevguid/m0025967/m0025967.asp|title=http://wonder.cdc.gov/wonder/prevguid/m0025967/m0025967.asp|accessdate=2008-05-06}} MMWR 42(RR16);1-25 Publication date: 12/31/1993</ref>.''
This hyperlink leads to the following text (copy and paste from the page):
More than a billion persons are at risk for this noninfectious condition, which is the leading preventable cause of intellectual impairment in the world (33). The number of persons affected is unknown, but prevalences of the most severe form, cretinism, often reach 3%-15% in areas where the disease is highly endemic. Goiter and hypothyroidism are other manifestations of the deficiency. The main risk factor involved is exclusive or nearly exclusive consumption of locally grown foods in areas where the soil is deficient in iodine.
Interventions include adding iodine to salt, tea, fish paste, or bread, at a cost of US $0.02-0.04 per person per year for iodized salt. Iodized oil is available in injectable or oral forms. Interventions for iodine deficiency can also be combined readily with interventions for vitamin A and/or iron deficiency. A new assay is available to measure levels of thyroid hormone in samples of blood from a fingerstick. Methods such as iodized salt were used to eliminate iodine deficiency disorders more than 40 years ago in Australia, England, New Zealand, Switzerland, and the United States. Bolivia and Ecuador have almost eliminated the condition. WHO has endorsed a goal of elimination of iodine deficiency disorder by the year 2000. There is great need for improved surveillance and estimates of the prevalence of these disorders and of their economic impact. Iodine deficiency disorders can be eliminated.

Comment
The reference text given here above does not mentioned what is claimed in the dubious paragraph.
Personally, I do not immediately see how iodine tincture can be used to detect and treat iodine deficiency.
So, I am highly skeptic on the suggested treatment. Thus, I removed the paragraph to avoid any health risk if any incompetent person would use it in an unreasonable way.

The article says Lugol's iodine is water free and aqueous, which doesn't make a lot of sense to me. Am i missing something? —Preceding unsigned comment added by 97.90.154.94 ( talk) 21:38, 14 July 2010 (UTC)
"Application of tincture or Lugol's to the skin also results in absorption and bioavailability of some moderate fraction of the iodine. The absorption time (disappearance of the skin stain) depends on the level of iodine already in the body as well as the condition of the skin, and varies from one or two hours in iodine-deficient persons to many hours in those having normal levels."
This seems suspicious (perhaps some evidence?), since Dr. David Derry, states on about.com ( http://thyroid.about.com/library/derry/bl2a.htm),
"The "test" of putting iodine on the skin to watch how fast it disappears is not an indicator of anything. The iodine disappearance rate is unrelated to thyroid disease or even iodine content of the body.(1-2) Meticulous research by Nyiri and Jannitti in 1932 showed clearly when iodine is applied to the skin in almost any form, 50% evaporates into the air within 2 hours and between 75 and 80 percent evaporates into the air within 24 hours."
I have found a copy of the Nyiri and Jannitti paper here,
http://jpet.aspetjournals.org/content/45/1/85.short
Unfortunately I can't find the other paper by Biskind,M.S. Penetration through tissue of iodine in different solvents. Proc Soc Exp Biol Med 30:35-37, 1932.

This paper http://becknaturalmedicineuniversity.com/doc/Bioavailability_of_iodine_applied_to_the_skin.pdf states that "the skin iodine patch test is not a reliable method to assess whole body sufficiency for iodine" for a variety of reasons explained in the paper. It also shows test data that confirm the body will readily absorb far more iodine than it needs, which means the test can't work anyway. I also see that the Nyiri and Jannitti paper referenced above states "The percentage of iodine penetration through the skin is the same, irrespective of whether the cells have a high or low vitality, or are dead, and irrespective of the direction of penetration. Activity of the cells, therefore, does not seem to be indispensable for the penetration of iodine." That seems pretty conclusive, so I'm removing the reference to this skin test. 98.234.112.116 ( talk) 03:52, 22 May 2011 (UTC)
Can someone knowledgeable add information about decolorized (colorless, white) iodine? Is it the same thing as the iodine in iodine tincture?
I tried to find information on this and most of the information seems to counteract each others so I cannot add anything to this article as I'm not sure what reference/citation is correct.

In the "Usage" section it is claimed that Tincture of Iodine is used to combat viruses. How can it combat viruses if a virus is not a living organism, as is a bacterium? 96.248.101.32 ( talk) 04:07, 6 December 2017 (UTC)Toddy Macfarlane
Can we have an explanation or wikilink to the meaning of "USP" please? I'm not sure if this is an Americanism which everyone assumes everybody else knows. But it would be helpful for those not aware of its usage. Thanks Nick Moyes ( talk) 21:05, 29 June 2022 (UTC)
