People who treat illnesses or injuries, ranging from doctors to alternative medicine practitioners.
From Old English 'hælan' (to make whole, healthy). The noun 'healer' has been used since before doctors were formalized, when wise people in communities treated the sick.
The word 'heal' and 'whole' come from the same root—meaning that to heal something is literally to make it 'whole' again, which is beautifully what doctors still try to do.
