Médaille Électro-Magnétique de Carolus



Médaille Électro-Magnétique de Carolus (Carolus's Electro-Magnetic Medallion) is an electrotherapeutic medical medallion, promising to generate a "double electric current" in the wearer, produced by the reaction of the varying metals constituting the battery with the wearer's skin (as a galvanic response), in order to purify the blood and regenerate the body to cure disease. It was advertised as having been created by Carolus of Paris and manufactured by Ferdinand De Boyeres.
