| | King's American Dispensatory, 1898: Acidum Gallicum (U. S. P.)—Gallic Acid. (Site not responding. Last check: 2007-11-07) |
 | | Before investigations were begun it was believed to exist ready-formed in galls, but in 1833 Pelouze showed that the larger portion of it was derived from the tannin of the galls, and advanced the theory that this conversion was accomplished by oxidization by the atmospheric oxygen, by which carbon dioxide was driven off. |
 | | Gallic acid does not coagulate albumen, and when ingested is quickly absorbed, and rapidly discharged by the kidneys, over the secretions of which, as well as of the skin, it has a marked control. |
 | | Gallic acid is much inferior to tannic acid as a topical astringent; but administered internally, it is more powerful as a remote astringent. |
