Black cumin (Nigella sativa) has a long history of use in traditional medicine systems, particularly in the Middle East, South Asia, and parts of Africa. In these traditions, black cumin seeds and their oil have been applied topically to wounds and cuts to support the stoppage of external bleeding and to promote healing. The rationale for this use is based on the seed's purported astringent, antimicrobial, and anti-inflammatory properties, which are believed to help constrict blood vessels and protect wounds from infection, thereby potentially reducing bleeding and supporting wound closure.

While there is some in vitro and animal research suggesting that Nigella sativa extracts possess anti-inflammatory, antioxidant, and antimicrobial effects, direct scientific evidence validating its hemostatic (bleeding control) effect in humans is limited. Most of the support for this application comes from traditional texts and ethnobotanical surveys rather than modern clinical trials. Some animal studies suggest that black cumin oil can promote wound healing, but these do not specifically address its ability to stop active bleeding. As such, the use of black cumin for external bleeding is primarily justified by traditional practice rather than robust scientific data.

In summary, black cumin's use for external bleeding is rooted in traditional medicine with some indirect pharmacological support, but it lacks high-quality, direct scientific evidence for this specific indication.
