Gallic Acid, or 3,4,5-trihydroxybenzoic acid, is produced by plants such as sumac, tea leaves, oak bark, and witch hazel; it provides the astringent property and antihemorrhoid activity of witch hazel. Derivatives are used in the production of azo dyes and photographic developers. It gets its name from gall nuts, which are the swelling of plant tissue in response to parasitic infection.
