Eupatorium perfoliatum is a native North American plant in the Asteraceae family. Its leaves grow “through” the stem—hence the name “perfoliatum.” Traditionally used by Native Americans for febrile illnesses, it was known for inducing profuse sweat and easing the pain of “break-bone fever.”

Historically used as a diaphoretic and emetic in herbal medicine to treat influenza, malaria, and rheumatic fevers. It was also taken as a hot infusion to promote sweating and clear mucus.

Proved by Dr. William E. Payne and introduced into homeopathy by Dr. C. Hering. Proving symptoms confirmed by Hering and Hale.

Eupatorium perfoliatum is the archetypal remedy for influenza with severe bone and muscle pain—the “boneset” state. It captures the collapse and suffering of febrile illnesses where the patient lies still, tormented by deep aching as if broken. Periodicity, thirst before chill, and relief from vomiting are hallmarks. It is a remedy of systemic suffering, where every structure—bone, muscle, mucosa—feels overwhelmed. The patient is silent, aching, and waiting for the sweat to bring mercy.

  • Indispensable in influenza with bone pain
  • Use in malaria, dengue, or post-viral syndromes with chill–fever–sweat cycle
  • Excellent in bronchitis or pneumonia with bruised chest and violent cough
  • Relieves migraine with nausea during fevers
  • Effective in intermittent fevers with great thirst and nausea before chill
