White Oak Bark

White Oak (Quercus alba/robur) is native to North America although it is now widespread in Europe and Asia. White Oak is also known as Tanner's Bark, English Oak, Red Oak, and Green Oak. The tree has been used for many centuries. In fact, in the King Arthur legends, the Round Table is made from a single slab of oak.

The bark is used for medicinal purposes. White Oak has an anti-inflammatory effect, and also acts as an astringent, tightening and drying the tissues. White Oak bark contains tannic acid which aids stomach and digestive complaints.
