Buckhorn Plantain (Plantago lanceolata) has been used in traditional herbal medicine for a variety of conditions, primarily for respiratory issues, wound healing, and inflammation. Its use to treat or support "chills" is documented in some folk traditions, especially in European and Native American herbalism, where chills were sometimes considered a symptom of an underlying imbalance or infection. In these contexts, Buckhorn Plantain was prepared as a tea or infusion, believed to help "drive out cold" or relieve symptoms associated with chills, such as feverishness or shivering, though this use is less common than its application for coughs or wounds.

However, there is no robust scientific evidence supporting the effectiveness of Buckhorn Plantain specifically for treating chills. Modern phytochemical studies focus primarily on its anti-inflammatory, antimicrobial, and demulcent properties, which are relevant to respiratory and skin health, but not directly to chills as a symptom or condition. Clinical trials or pharmacological studies investigating its effects on thermoregulation or the physiological mechanisms of chills are lacking. Thus, while there is some historical precedent for its use in this context, the evidence is minimal and not substantiated by contemporary science.
