Synopsis

Source of validity: Traditional
Rating (out of 5): 2

Tannins, a group of polyphenolic compounds found in various plants, have a long history of traditional use in the management of minor wounds and abrasions. Their astringent properties, which cause the contraction of skin and mucous membranes, have been valued in folk medicine across different cultures for promoting wound drying and forming a protective barrier. In traditional herbal medicine, plant extracts high in tannins—such as witch hazel, oak bark, and tea—have been applied topically to minor cuts, abrasions, and skin irritations to help reduce bleeding and potentially limit infection.

However, the scientific validation for the use of unspecified tannins in treating abrasions is limited. Some in vitro and animal studies suggest that tannins may have mild antimicrobial and anti-inflammatory effects, which could theoretically support wound healing. Still, robust clinical trials in humans specifically evaluating tannin-rich preparations for abrasions are lacking. Most modern wound care guidelines do not recommend tannin-based treatments due to insufficient evidence regarding efficacy and safety. Therefore, while the use of tannins for abrasions is primarily justified by tradition, the scientific evidence supporting their effectiveness is weak, warranting a low rating.
