Gallic acid is an organic acid that can occur by itself or as part of hydrolyzable tannins, which are types of tannins that yield this acid upon heating with hydrochloric acids. Its name is a reference to oak galls: abnormal swellings of plant tissue historically used in the preparation of tannic acid. Gallic acid can be obtained from a variety of plant-based sources, such as witch hazel, blueberries, watercress, flaxseed, and tea.
Foods known to be rich in gallic acid, like blueberries and witch hazel, have been used as natural remedies by all kinds of cultures. For example, Native Americans made aromatic teas from blueberries and gave these to women in labor as relaxants. Nowadays, gallic acid is largely known for being an antioxidant with potent medicinal properties such as that of an antifungal and antiviral agent.

Persons involved in the handling of commercial gallic acid should be careful around it as it can irritate the skin and eyes.
