Laudanum.
Paracelsus probably invented the name of laudanum, and seems to have called several medicines by that term. In one place he expressly states that his laudanum was made from gold leaf and unperforated pearls; in other places he seems to mean red precipitate, and undoubtedly opium or a compound of it was sometimes intended. Crollius gives a formula for a pill mass, which he designates the laudanum of Paracelsus, which contained one-fourth of its weight of opium, to which were added henbane juice, mummy, salts of pearls and corals, the bone of the heart of a stag, bezoar stone, amber, musk, unicorn, and some species, with a few drops of many of the essential oils. The Anodynum Specificum of Paracelsus was a product obtained by first digesting opium, 4, in a mixture of orange and lemon juices, 180, with distilled frogs’ sperm water, to which cinnamon, 4, cloves, 45, ambergris, 4, and saffron, 45, were added. This mixture was digested for a month, and after pressing and straining, coral, magistery of pearl, and quintessence of gold, of each 2, were added, together with the salt extracted from the marc.
The laudanum of the early London Pharmacopœias was a pill mass made as follows:—Thebaic opium extracted by spirit of wine, ℥i.; saffron, similarly extracted, ℥iss; castorum, ℥i; combined with ℥ss. of species of diambræ made into a tincture with spirit of wine; to these might be added, ex-gratia, ambergris and musk, of each 6 gr., and oil of nutmeg 10 drops. Evaporate the moisture and leave the mass.
One would think that the name laudanum was an echo of laudandum, and that has been the usual opinion. But Professor Skeat is confident that it is a variation of ladanum, which, he says, was a stomachic cordial made and named from gum labdanum, which had been in medical use for centuries. This, of course, is possible, but it must be remembered that Paracelsus was untrammelled by any etymological rules in his invented words, and that the one unlikely thing for him to do would have been to adopt with a slight modification the name of a remedy then in use, if, indeed, a preparation of labdanum was at that time popular, or even known at all in Germany in his time.[2] Adam of Bodenstein, son of the theologian Carolstadt, who wrote both for and against Luther’s doctrines, wrote a treatise in which he professed to explain all the mysterious terms used by Paracelsus. Laudanum, he says, is from a laude, and was a quintessence of mercury and not an opiate.
Sydenham’s Laudanum is the preparation of opium which attained the highest popularity. It has always been the principal liquid preparation of the drug in continental practice, and formulas for it more or less corresponding with the original are in all the principal Pharmacopœias except the British. It was omitted from the P.L. in 1746, or rather a very similar preparation named Tinctura Thebaiaca was substituted for it. Sydenham’s formula, which was given incidentally in his description of the dysentery of 1669–72, prescribed strained opium, 2 oz., saffron 1 oz., cinnamon and cloves of each 1 drachm, and Canary wine, 1 pint.
“I do not think this preparation has more virtue than the solid laudanum of the shops,” he wrote; “but I prefer it before that for its more commodious form, and by reason of the greater certainty of the dose, for it may be dropped into wine or any distilled water, or into any other liquor.”
This passage is quoted from Pechey’s translation of Sydenham’s works. The allusion to “the solid laudanum of the shops” confirms the opinion that Sydenham’s was the first liquid preparation generally designated laudanum. Among the Sloane manuscripts in the British Museum is included what is described as “The Commonplace Book of an Apothecary at Great Dunmow,” which contains several more or less similar recipes for laudanum. The book is dated 1644–5. The most elaborate formula is headed “Laudanum Josephi Michælis,” and lengthy directions for making this are given. The ingredients were opium, extract of henbane, species diambræ (a compound of most of the known spices), pearls, coral, amber, musk, mummy, cloves, and oil of cloves. Some of these were to be extracted with spirit of wine, and the spirituous extracts were to be distilled. Ultimately the whole was to be set aside to ferment for three months. The dose was stated to be 4 or 5 grains at bedtime.
Rousseau’s laudanum, which also became famous among opium preparations, differed from others in being a fermented compound. It was made by dissolving 12 oz. of honey in 3 lb. of warm water, and setting the mixture in a warm place. When it began to ferment, 4 oz. of opium mixed with 12 oz. of water were added, and the fermentation was allowed to continue at a moderate temperature for a month. After straining, the liquid was evaporated to 10 oz., and 4½ oz. of alcohol were added.
Rousseau was a Capuchin monk and was destined for mission work in Asia. Sent from Rome to Paris to study medicine so that he might be better fitted for his life’s work, he carried a letter of introduction to Colbert, the first minister of Louis XIV. Rooms were provided for him in the Louvre, and there before long he set up a laboratory and began to prepare and sell medicines. The Capucin of the Louvre became the fashionable quack, and Louis ordered the Faculty of Medicine to confer on him a degree. The life was so agreeable that, when orders came from Rome that he was to proceed on his mission, Rousseau refused, and, having transferred his allegiance to the order of Cluny, he continued his medical practice in Paris. Falling ill he refused medical aid, treated himself with his own compounds, and died. After his death his brother published his “Remédes et Secréts Eprouvés” (1697).
Black Drop was the name of a celebrated proprietary medicine very popular from the first half of the eighteenth, until the early part of the nineteenth century. Its inventor was one Edward Runstall of Bishop Auckland in the county of Durham, but it also came to be known as the Lancaster or the Quaker’s Black Drop. A formula for it was found by a Dr. Armstrong among the papers of a relative of the proprietor, and was published in a treatise on fevers in the early part of the nineteenth century. The recipe was as follows:—Opium, ½ lb.; good verjuice (the juice of the wild crab), 4 pints; nutmegs, 1½ oz.; saffron, ½ oz. Boil to a proper consistence, set in a warm place, add two spoonfuls of yeast, set in a warm place for six or eight weeks, then in the open air until it becomes of the consistence of syrup. Decant, filter, and bottle, putting a little sugar into each bottle.
This preparation was three times the strength of laudanum. The acetum opii of the Edinburgh and Dublin Pharmacopœias was intended as a substitute, but closer approximations to the original formula were given in the Hamburg Codex of 1845 and in the U.S. Pharmacopœia of 1851. The growing favour with which morphine was regarded gradually destroyed the popularity of the Black Drop.
