Synopsis

Source of validity: Traditional
Rating (out of 5): 3

Tannins are astringent polyphenolic compounds found in many plants and have a long history of traditional use for managing external bleeding. Historically, various cultures have applied tannin-rich plant extracts (such as witch hazel, oak bark, and tea leaves) to wounds to stop bleeding and promote the healing of minor cuts and abrasions. The astringent action of tannins causes proteins in skin and mucous membranes to precipitate, leading to vasoconstriction and the formation of a protective layer over wounds, which can help reduce bleeding.

While the empirical use of tannin-containing preparations for minor external bleeding is well-documented in ethnobotanical literature, scientific validation remains limited. Some in vitro and animal studies demonstrate that tannins can promote hemostasis (the process of stopping bleeding) by constricting blood vessels and aiding clot formation. However, there is a lack of large-scale, high-quality clinical trials in humans specifically evaluating the efficacy of tannins for external bleeding.

Overall, the practice is primarily supported by traditional knowledge and some mechanistic understanding rather than robust clinical evidence. Tannin-rich preparations are still used in folk medicine and some over-the-counter products, but their use should not substitute for standard medical care in the case of serious or persistent bleeding.
