"Bobby, we know he's gravely injured, say yes, we'll heal him, say no, he'll never walk again." - Zachariah talks about healing
Healing is the ability (literally, the act) of alleviating or ameliorating injury and wounds. The efficiency of it varies from healer to healer.
This is a separate ability to healing factor or regeneration as it is one being able to heal another, not just themselves.
Like resurrection, for angels to heal, they require the power of Heaven.
Characters with this ability

- Angels - Through the power of heaven
- Reapers - By trasferring aliment to someone else

- Alastair - In Hell, he was able to torture people to unimaginable degrees eventually leading to 'death', and he was able to heal every wound.
Notes
