Spanish Fly refers to beautiful, iridescent green insects, Cantharis vesicatoria, which contain cantharidin, which is both a vesicant and a diuretic. |
Cantharis vittata was collected as a substitute for Cantharis vesicatoria, which was used in blistering plasters. |
We recommended that she take Cantharis immediately, and she was much improved by the following day and needed no conventional care. |
