Gallnut Extract Powder is derived from galls, which are abnormal growths formed on plants (especially oak trees) in response to insect activity, typically from wasps laying eggs. These galls are exceptionally rich in tannins, and the extract is a concentrated source of them.

The most prominent and well-studied compound in this extract is Tannic Acid, a specific type of hydrolyzable tannin. It is crucial to understand that while all tannic acid is a tannin, not all tannins are tannic acid. This extract is prized for its potent astringent and protein-binding properties.
