Spanish fly can mean two things. It is the name of a green blister beetle (cantharis vesicatoria) found in southern and central Europe. Spanish fly or cantharide also implies a toxic preparation of the crushed, dried out bodies of this beetle, used in homoeopathy as a treatment for skin blisters and as an aphrodisiac.
The Spanish fly produces a poisonous substance called cantharidin, which generally affects the urinary tract and causes vomiting and burning pain. Homoeopathy with its foundation firmly placed in the Law of Similars presents a doctrine that strives to cure a symptom with a diluted medication manufacturing the same symptom in heavier amounts. In other words, the homoeopathic remedy of treatment with Spanish fly is mainly prescribed for illnesses that have burning pain as a symptom.
