Botanical Overview
Northern Red Oak (Quercus rubra) belongs to the Fagaceae family. Limited but reliable traditional records indicate this plant has recognized medicinal applications in one or more healing traditions. The beech family (Fagaceae) includes trees with simple, alternate leaves and inconspicuous flowers arranged in catkins. The fruits are nuts partially enclosed in a woody cupule (acorns in oaks). This family dominates many temperate and subtropical forests and provides tannins with astringent medicinal properties.
