I wish the ER would have put this stuff in a dog bite wound I had in 2001 (a chunk taken out of my calf). It took two months to heal---doctor would not stitch it because it might seal in infection. I had it covered with a big bandage all that time and as a result, developed an allergy to the bandage adhesive. While it was interesting to watch the healing progress, new tissue, fat layer, and skin grow, it would have been better to have some better protection for the wound. Something that promoted healing. Got a big scar to match the teeth marks (puncture wounds) on the front of my calf.
