text: Italian Paracelsianism and chemical medicine from the mid-sixteenth century to the mid-seventeenth century, developed institutionally and intellectually with the introduction of chemical remedies in Italy. Paracelsian views were accepted wherever alchemy and practical chemistry were predominant, as in the Medici court in Florence. In Italy, Germany, England and France royal patronage supported Paracelsianism and new medicines were adopted by distillers, apothecaries and physicians. During this time, Sala advanced on Paracelsianism through his publishing in the new "chemical" medicine and the analysis of Vitriol, which he dedicated to the banker Bonaventura von Bodeck. The principle in chemistry that the names of a compound should indicate its constituents was recognised in Salas suggestion that the residue of the calcination of green vitriol (i.e. ferric oxide) might be called Substantia Ferrea Vitrioli as an improvement on the Paracelsan colcothar'.
