Can trees heal like people can?
People are able to heal by regenerating injured tissue. For example, a cut on your finger quickly heals, so that several weeks later, the injured area is hardly noticeable. Trees are unable to replace injured tissue. Instead, they form boundaries around it which seal the area from the rest of the tree. The wood within the area which has been sealed off can no longer supply the rest of the tree with stored food. Additional injuries seal off more wood in this manner. Save-A-Tree gives the tree what it needs to deal with the stress of an injury.
