Home remedies for frostbite include getting out of cold, protecting the skin from further cold exposure, rewarming frostbitten areas, taking pain medication and wrapping thawed areas to avoid refreezing, notes Mayo Clinic. A person should also not walk on frostbitten feet, as this further damages the condition.
A person should put a dressing between frostbitten toes or fingers to keep them separated, states MedlinePlus. Rewarming the affected areas involves soaking them in warm water for about 20 to 30 minutes. Over-the-counter medications, such as ibuprofen, help ease pain and inflammation. If frostbite is severe, a person should drink warm liquids to replace any lost fluids.
