If you had early signs of paralysis and you were really good at asking personal questions, you might figure out that this paralysis someone has is from syphilis, in which case you could give this nice concoction of mercury and arsenic — as long as you didn't overdose them and kill them.
Si un paciente presentaba síntomas iniciales de parálisis y uno era bueno haciendo preguntas personales podía descubrir que esa parálisis era a causa de sífilis, en cuyo caso se podía administrar un buen brebaje de mercurio y arsénico, siempre y cuando no le dieras una sobredosis y mataras al paciente.
