Wizarding approaches to sickness and injury differed from Muggle medicines. Healers were qualified in using healing magic, a mix of potions magical herbs and charms. Hogwarts had its own healing hospital and nurse, Madam Pomfrey, whilst St Mungo's Hospital for Magical Maladies and Injuries was well known as the heart of healing in the wizarding world.

Healers were able to treat well known magical maladies including Dragon Pox, Spattergoit and vanishing sickness, as well as more serious long-term injuries. For instance, Neville's parents, Frank and Alice Longbottom were tortured to insanity by Death Eaters, and had round-the-clock care at St Mungo's indefinitely.
