Synopsis

Source of validity: Traditional
Rating (out of 5): 1

Black walnut (Juglans nigra) has a long history of use in traditional herbal medicine, primarily for its purported antimicrobial, antifungal, and astringent properties. In North American folk medicine, black walnut hulls were sometimes applied topically for skin conditions, including minor wounds, eczema, and bruises, based on the belief that their astringent and tannin-rich content could help "draw out" impurities and support healing. However, this use is primarily anecdotal, with little to no documentation of systematic use specifically for bruises in major historical texts; rather, it is more broadly associated with skin afflictions. There are no high-quality clinical studies or pharmacological investigations directly supporting the efficacy of black walnut for bruise healing. The main active compounds, such as juglone and tannins, have demonstrated antimicrobial effects in laboratory settings, but their role in tissue repair or hematoma resolution has not been substantiated in scientific literature. Therefore, the evidence for using black walnut to treat or speed the healing of bruises is weak and based largely on tradition and extrapolation from its general topical uses in folk medicine, rather than robust scientific validation.
