White oak (Quercus alba) has a long history of use in traditional herbal medicine, particularly among Native American and early European settlers in North America, for the treatment of minor wounds such as scratches and abrasions. The inner bark of the white oak tree contains significant amounts of tannins, which have astringent properties. These astringents are believed to help contract tissue, reduce local bleeding, and create a protective barrier over minor wounds, potentially promoting healing and preventing infection. Historical texts and ethnobotanical sources reference the preparation of poultices or washes made from white oak bark for topical application on skin injuries.

However, while the astringent and mildly antiseptic qualities of tannins provide a rationale for such traditional use, there is limited direct scientific research specifically validating the efficacy of white oak bark on scratches and abrasions. Most contemporary support is extrapolated from the general properties of plant tannins, rather than controlled clinical studies on white oak itself. As a result, while the use of white oak for this purpose is well documented in traditional contexts and is plausible based on the known actions of its constituents, the evidence base remains largely historical and anecdotal rather than rigorously scientific. For minor, superficial wounds, white oak preparations may offer some benefit, but they should not replace modern wound care practices for more serious injuries.
