Healing is the biological ability of a DNA Alternate to accelerate cell division and induce regeneration in biotic subjects. This ability accelerates the processes by which damaged or infected organic material heals, or regenerate damaged organs and missing limbs. This ability can even be used to cure diseases that have no cure.
The Alternate draws from their own chemical energy to use this ability, and so has a limit on how much healing they can do before they have depleted their own energy reserves dangerously low. When regenerating lost limbs, the subject must ingest the nutritional components to provide the biomass. As in all extraordinary abilities, the law of conservation mass is absolute.
