White oak (Quercus alba) has a long history of use in traditional herbal medicine, especially among Native American and early European settlers in North America. Its bark is rich in tannins, which are astringent compounds thought to help "dry up" discharges and reduce inflammation. Historically, white oak bark was applied topically or used as an eyewash to treat minor eye irritations, conjunctivitis, or infections. Herbal texts from the 19th and early 20th centuries reference its use for this purpose, often emphasizing its astringent and antimicrobial properties.

However, the scientific evidence supporting white oak bark for eye infections is minimal. While laboratory studies show that oak bark extracts can have some antibacterial effects, these studies do not specifically address eye infections, nor do they establish safety or efficacy for ophthalmic use. Modern herbalists may still reference its traditional use, but there is a lack of rigorous clinical trials or modern evidence validating its effectiveness or safety for treating eye conditions. Moreover, the use of tannin-rich substances in the eye carries potential risks, such as irritation or allergic reaction.

In summary, white oak's association with treating eye infections is rooted in tradition rather than science. Anyone considering herbal remedies for eye health should consult a qualified healthcare provider to avoid potential harm.
