This remedy earned the name ‘boneset’ as an herb used to purge ‘bone breaking’ fevers by encouraging perspiration. As ‘like cures like’, the homeopathic Eupatorium applies best to flu or colds marked by aching bones, muscles and even eyes, plus shivering chills and throbbing headaches. Except for the sharp headaches which may or may not begin with the flu, all its symptoms improve with sweating and rest and are marked by restlessness and a great thirst for cold drinks and hunger for ice cream.
