A healer is a person who heals or treats the wounded people of their district. One notable healer of District 12 is Mrs. Everdeen who healed many of the injured in the district, such as coal miners in accidents and Gale after he was brutally whipped by Romulus Thread. Primrose Everdeen also takes an interest in healing after assisting her mother countless times. It is substantial that a healer is calm and willing to do whatever it takes to keep a patient alive. Healers like Mrs. Everdeen used numerous plants and natural substances as medicines while helping a patient. Some of these plants are found in the wild, such as the woods and meadows. On occasion she will use fever pills and sleep syrup, or even morphling.
Another notable healer is Primrose Everdeen, who helps Mrs. Everdeen heal people. She is young, but she has gotten the blood of her healer mother and naturally had a great ability to heal people. After the bombing of District 12, when Gale collected more than 900 people and escaped out the forest, Prim and her mother set up a medical area and healed injured people who survived out of the fire. They had very few things to treat from, but they tried their best by gathering whatever they could from the forest.
Since the districts do not have official hospitals or doctors, a healer is their main source of medical care and is equivalent to a doctor. It is mentioned in Mockingjay that District 8 had a hospital in the rebellion but it is unknown whether there were actual doctors or healers there.
After Gale's whipping, when Mrs. Everdeen and Prim were healing him, Mrs. Everdeen remarked that it was lucky that they had snow for a snowcoat. When Katniss asked what she did in the summer, Mrs. Everdeen put on a weary face and replied: "Tried to keep the flies away."
