White Oak Bark (Quercus alba)
White oak is a medium-sized hardwood tree native to the woodlands of eastern North America and Canada. The bark of the tree has a rough texture that is characteristic of other oaks and a mottled appearance of light grey to greyish-white colored areas.
Contrary to its common name, the tree’s bark is actually grey, not white. White oak is prized for furniture and even boat making because of its beauty and durability. The hull of the 18th century frigate, the USS Constitution, was made from white oak.
The bark of white oak is attributed with astringent, antiseptic and anti-inflammatory qualities, largely due to a high content of tannins. While the bark may be prepared as a tea or tonic, it is most commonly tinctured. The bark is also used to produce decoctions for teas, infusions and tonics as well as topical formulations for skin care preparations.
The bark has been regarded as a food source in times past and a good source of iron and B-12.
