Pedunculate Oak
OTHER NAME(S): Chêne Pédonculé, Corteza de Roble, Eichenrinde, English Oak, European Oak, French Oak, Pelarek, Quercus Cortex, Tanner's Bark, Tanner's Oak, Quercus robur, Quercus pedunculata, Roble Pedunculado, Chêne pédonculé
Overview
Pedunculate oak (Quercus robur) is a type of oak tree commonly found in Europe. Its bark contains high amounts of antioxidants called ellagitannins.
Pedunculate oak might have anti-inflammatory and antioxidant effects, which are likely due to the ellagitannins in its bark.
People use pedunculate oak for chronic fatigue syndrome (CFS), liver damage caused by alcohol, athletic performance, wound healing, and many other conditions, but there is no good scientific evidence to support these uses.
