Rating (out of 5): 2

Moss has been used traditionally in various cultures to support or treat injuries, particularly as a wound dressing. Historical records indicate that certain types of moss, such as sphagnum moss, were utilized by Indigenous peoples and during wartime (notably in World War I) as a natural wound dressing. This traditional use was based on moss’s high absorbency, softness, and mild antimicrobial properties. Sphagnum moss, in particular, can absorb several times its weight in liquid, making it effective at keeping wounds dry and reducing the risk of infection. Its slight acidity (low pH) may have also contributed to inhibiting bacterial growth.

However, while there is some laboratory evidence supporting the antimicrobial properties of sphagnum moss, modern scientific validation through rigorous clinical trials is lacking. The evidence for efficacy mainly comes from anecdotal reports, historical documentation, and basic microbiological studies. In modern medicine, moss has been largely replaced by sterile, manufactured wound dressings that are more consistent and safer. Nonetheless, in emergency or wilderness situations, moss may still be considered as a last-resort dressing due to its availability and traditional precedent.

In summary, the use of moss for injuries is rooted in traditional practice with some supportive laboratory evidence, but lacks strong modern clinical support.
