White oak is a North American species of tree most often found in the forest growing alongside pine, poplar and maple, but is also frequently found growing on the shores of lakes, ponds and other bodies of water. Its leaves and twigs are the preferred nesting material for many small animals and birds, while its wood is coveted by mission-style furniture makers. White oak bark is valued for its astringent qualities and as a source of vitamin B-12 and iron. As such, it is traditionally decocted or tinctured or used to make teas and tonics.

White oak is distributed throughout the northeastern U.S. and Canada, although it does occur further west as evidenced by the fact it is the state tree of Connecticut, Maryland and Illinois. For centuries, the wood of the tree has been used to build ships, wine barrels and authentic mission-style furniture.
White oak powdered bark, which contains up to 20% tannins, potassium, iron and vitamin B-12, is added to tonics and teas or is encapsulated. The herb is also used to make astringent washes and pastes for topical use.
