No, we aren’t talking about the Peg who lives down the street and collects lawn ornaments. PEG stands for polyethylene glycol, a nontoxic molecule that when injected intravenously can help to repair cellular membrane damage in the corpus callosum area of the brain.

PEG eliminates the amyloid precursor protein (APP) that builds up as a result of traumatic axonal brain injuries. When this protein begins to accumulate, cells begin to die.

Not only does research find PEG benefiting brain injuries, but studies have also shown that it has helped repair nerve membranes after spinal cord injuries in guinea pigs. While PEG has been tested on animals up to this point, a good deal of the research has promising human application.
