His Pharmacy.
The composition of Paracelsus's laudanum, the name of which he no doubt invented, has never been satisfactorily ascertained. Paracelsus himself made a great secret of it, and probably used the term for several medicines. It was generally, at least, a preparation of opium, sometimes opium itself. He is believed to have carried opium in the pommel of his sword, and this he called the "stone of immortality."
Next to opium he believed in mercury, and was largely influential in popularising this metal and its preparations for the treatment of syphilis. It was principally employed externally before his time. He mocked at "the wooden doctors with their guaiacum decoctions," and at the "waggon grease with which they smeared their patients." He used turpith mineral (the yellow sulphate), and alembroth salt (ammonio-chloride), though he did not invent these names, and it is possible that he did not mean by them the same substances as the alchemists did. Operinus states that he always gave precipitated mercury (red precipitate, apparently) as a purgative. He gave it in pills with a little theriaca or cherry juice. This he also appears to have designated laudanum. It is certain that he gave other purgatives besides.
It must be admitted that if Basil Valentine is a mythical character, the reputation of Paracelsus is greatly enhanced. Nowhere does the latter claim to have been the first to introduce antimony into medical practice, but it is certain that it could not have been used to any great extent before his time. If we suppose that the works attributed to Basil Valentine were fictitious, so far, that is, as their authorship is
