wound balm

Wound balm contains polymer, willow bark extract, colloidal silver, and colloidal copper.
The polymer forms a vapor-permeable layer. This prevents rainwater from entering the treated wound while still allowing evaporation. The silver and copper help keep the now-dry wound clean, while the willow bark extract promotes the formation of additional wound tissue (callus).

Avenue tree growers who use wound balm to treat pruning wounds on softer wood species report high satisfaction. The (pruning) wounds of trees such as linden, elm, and maple remain dry and heal quickly.
