Cantharis
Cantharis vesicatoria (Spanish fly)
Cantharis, from the Spanish fly, is a homeopathic remedy whose great keynote is intense, violent burning — especially of the urinary tract (cystitis, UTI) with cutting pains before, during and after urination — and of burns and scalds.
This is general information about a homeopathic remedy, not a prescription or dosing advice. In homeopathy the correct remedy and potency are chosen for the whole individual symptom picture by a qualified homeopath — the same remedy is not right for everyone. Do not self-medicate, and consult a qualified homeopathic doctor (and your physician for serious or persistent conditions) before taking any remedy.
