Rating (out of 5): 3

Tannins are a group of polyphenolic compounds found in many plants, including oak, witch hazel, and tea. Their use in supporting or treating external bleeding is primarily justified by traditional medicine practices. Historically, tannin-rich plant extracts have been applied topically to wounds to promote hemostasis. The astringent property of tannins causes proteins in tissues and blood to precipitate, leading to vasoconstriction and the formation of a protective layer over the wound, which helps reduce bleeding and may also provide some antimicrobial effect.

Numerous ethnobotanical records document the use of tannin-containing plants in folk medicine for wound care and bleeding control. For instance, powdered bark or leaves of certain trees rich in tannins have been traditionally used to stop minor cuts and abrasions from bleeding. While there is some mechanistic plausibility and limited in vitro or animal data supporting the astringent and antimicrobial effects of tannins, high-quality clinical trials in humans are lacking. Thus, scientific validation is limited, but the traditional use is well established.

In summary, the use of tannins for external bleeding is rooted in traditional practice with moderate evidence from historical use and basic science, but lacks robust modern clinical research to confirm efficacy or safety.
