Febrifuge agents work by cooling the body, supporting perspiration, or modulating the immune response to address the underlying causes of fever. These remedies are particularly useful during infections or inflammatory conditions. Elderflower (Sambucus nigra) is a gentle febrifuge that promotes sweating to reduce fever naturally. Willow bark (Salix spp.) contains salicin, which helps lower body temperature and alleviate fever-related discomfort. Yarrow (Achillea millefolium) supports circulation and encourages sweating, helping to break a fever. These herbs provide a natural, holistic approach to fever management while supporting the body’s healing process.
