What is cantharidin?
Answers:
Cantharidin (C10H12O4) is the lactose of cantharidic acid and the active constituent of cantharides - dried Spanish flies "Lytta vesicatoria". It has been used as an aphrodisiac and was formerly used as a counter-irritant in plaster form and in small quantities in hair lotions, but is liable to cause nephritis (kidney disease of toxic origin). - from Butterworth's Medical Dictionary
Cantharidin is a poisonous chemical compound secreted by many species of blister beetle, and most notably by the Spanish fly, Lytta vesicatoria.
Cantharidin is a poisonous chemical compound secreted by many species of blister beetle, and most notably by the Spanish fly, Lytta vesicatoria.
Cantharidin was first isolated by Pierre Robiquet in 1810. It is an odorless and colorless solid at room temperature. It is secreted by the male blister beetle and given to the female during the mating. Afterwards the female beetle will cover its eggs with it as a defense against predators. The complete mechanism of the biosynthesis is currently unknown. If cantharidin is ingested by human males, as it is excreted by the kidneys it irritates the urinary tract causing spectacular swelling, called priapism, but this is quite painful and does not result in arousal.
Diluted, it can be used to remove warts and tattoos. In addition, it can be used to treat the small papules of Molluscum contagiosum. However, when ingested 10 mg is usually a fatal dose.-
