Fever is an elevation of body temperature above the normal range of 36.6-37.2°C due to a resetting of the body's thermoregulatory system. It is not itself a disease but a response to infection or other pathogens. Studies show fever may be beneficial by aiding the immune system's response. Treatment focuses on staying hydrated and using measures to promote heat loss like wet clothes or baths. Homeopathy treats the individual patient rather than just the fever and matches a remedy based on all symptoms.
