Pharmacosiderite is a hydrated basic ferric arsenate, with chemical formula KFe4(AsO4)3(OH)4·(6-7)H2O and a molecular weight of 873.38 g/mol. It consists of the elements arsenic, iron, hydrogen, potassium, sodium and oxygen. It has a Mohs hardness of 2 to 3, about that of a finger nail. Its specific gravity is about 2.7 to 2.9, has indistinct cleavage, and is usually transparent or translucent. It has a yellow or white streak and a yellow, green, brown or red color. Its lustre is adamantine, vitreous and resinous, and it has conchoidal, brittle and sectile fracture.

  • La farmacosiderita és un mineral de la classe dels arsenats. Va ser descoberta el 1813 en una mina a prop de Camborne, al comtat de Cornualla, i anomenada així per Johann Friedrich Ludwig Hausmann, del grec pharmakon, verí, i sideros, ferro. Forma part del supergrup i del grup farmacosiderita, als quals dona nom. (ca)
  • La farmacosiderita es un mineral de la clase de los minerales fosfatos, y dentro de esta pertenece al llamado “grupo de la farmacosiderita”. Fue descubierta en 1813 en una mina de cerca de Camborne, en el condado de Cornualles (Reino Unido), siendo nombrada así del griego φάρμăκου —veneno— por su contenido en arsénico y σίδηρος —hierro— por tener este metal.​ Un sinónimo poco usado es el de arseniatozeolita.

  • La farmacosiderite è un minerale, un arseniato basico e idrato di potassio e ferro, appartenente al gruppo omonimo. Il nome deriva dal greco φὰρμακον = veleno e σίδερον = ferro, potente veleno per il contenuto in arsenico. Descritta per la prima volta da (22 febbraio 1782 - 26 dicembre 1859), mineralogista tedesco, nel 1813. (it)
