A Mediwitch or Mediwizard is a witch or wizard who specializes in the magical medical field, serving as the magical equivalent of a Muggle nurse or paramedic. The term is most prominently used to describe the matron of the Hogwarts Hospital Wing, Madam Poppy Pomfrey. The more formal and general term for a magical medical professional, akin to a doctor, is Healer. These individuals possess extensive knowledge of Healing Magic, Potions, and the treatment of magical ailments and injuries, ranging from common accidents to the effects of Dark Magic.
The primary responsibility of a Mediwitch or Healer is the diagnosis, treatment, and care of patients suffering from magical maladies. Their skills are essential for repairing damage that would be permanent or fatal in the non-magical world.
Mediwitches and Healers are primarily employed in dedicated magical healthcare institutions.
The term “Mediwitch” is a portmanteau.
The gender-neutral and more common professional title appears to be “Healer.”
