thread_title:  Synthetic route for Gallic acid -> Mescaline 

message: Early photographers, including Joseph Bancroft Reade (1801–1870) and William Fox Talbot (1800–1877), used gallic acid for developing latent images in calotypes. It has also been used as a coating agent in zincography.
Claims made on behalf of Joseph Bancroft Reade (1801–1870) were shown by RD Wood  to be erroneous he was working with Silver Nitrate; only AgNo3, AgBr, AgI, and  theoretically AgF [ie silver chloride/bromide/iodide] have the potential to develop the latent negative image.[See British Journal of Photography, 28 July 1972, Volume 119, No. 5845, pp.644–646, 643]  — Preceding unsigned comment added by Michael W Gray (talk • contribs) 14:11, 23 October 2013 (UTC)

message: As I am a German Wikipedia user, I read in the German article that the pKa (or pKs as it is called in german) is not 4.5 but 3.13 wich seems correct according to the literature (e.g. Bykova L.N., Petrov S.I.& Blagodatskava Z.G. (1970). Relative acidity of phenol and its derivatives in a medium of nonaqueous solvents. Zh. Obshch. Khim., 40, 2295-3000. and the citation No 3 from the german article). I also think that a higher acidity could be expected than for benzoic acid. This thought also fits following german article (you SHOULD translate that one too, if possible) http://de.wikipedia.org/wiki/Hydroxybenzoes%C3%A4uren (Hydroxybenzoesäuren).  — Preceding unsigned comment added by 134.130.112.64 (talk) 20:04, 2 November 2011 (UTC)

message: That George Washington's spies used gallic acid as an invisible ink is supposedly mentioned in "Episode 2: Revolution" of the series "America:  The Story of Us", which was broadcast by the U.S. cable TV channel, the "History Channel".
However, in "Chapter 4:  711 and the Sympathetic Stain" (pages 101-124) of his book Washington's Spies:  The story of America's first spy ring (New York, New York:  Bantam, 2006), author Alexander Rose states that one of Washington's spies, Abraham Woodhull, used an invisible ink when he wrote to George Washington, who then used a developing solution to read the writing.  However, Rose states that the nature of the invisible ink and the developing solution are unknown -- although Rose speculates that the invisible ink was gallic acid and that the developing solution was iron sulfate.
So I think that this claim -- that Washington's spies used gallic acid -- should either be deleted or tagged as "dubious".

"Gallic acid seems to have anti-fungal and anti-viral properties. Gallic acid acts as a antioxidant and helps to protect our cells against oxidative damage. Gallic acid was found to show cytotoxicity against cancer cells, without harming healthy cells. Gallic acid is used a remote astringent in cases of internal haemorrhage. Gallic acid is also used to treat albuminuria and diabetes. Some ointment to treat psoriasis and external haemorrhoids contain gallic acid."
