White oak bark

Traditional Uses & Why Herbalists Value It

North American herbalists prepare white oak bark as washes and mouth rinses for its pronounced astringency. The tannins give the preparation a tightening, drying character. European oak-bark monographs describe related uses for specified European species, while white oak is Quercus alba.

What Modern Research Has Found

Research on oak bark identifies tannins as the main source of astringency. European monographs document traditional uses for specified oak species, while robust human trials of Quercus alba preparations remain limited.

Plant Part, Preparation & Natural Constituents

Tannins supply astringency. Species-specific evidence should not be silently transferred from European oak bark.
