Theriac facts for kids
Theriac or theriaca is a medical concoction originally labelled by the Greeks in the 1st century AD and widely adopted in the ancient world as far away as Persia, China and India via the trading links of the Silk Route. It was an alexipharmic, or antidote, considered a panacea, for which it could serve as a synonym: in the 16th century Adam Lonicer wrote that garlic was the rustic's theriac or Heal-All.
The word theriac comes from the Greek term θηριακή (thēriakē), a feminine adjective signifying "pertaining to animals", from θηρίον (thērion), "wild animal, beast". The ancient bestiaries included information—often fanciful—about dangerous beasts and their bites. When cane sugar was an exotic Eastern commodity, the English recommended the sugar-based treacle as an antidote against poison, originally applied as a salve. By extension, treacle could be applied to any healing property: in the Middle Ages the treacle (i.e. healing) well at Binsey was a place of pilgrimage.
Norman Cantor observes that the remedy's supposed effect followed the homeopathic principle of "the hair of the dog", whereby a concoction containing some of the poisonous (it was thought) flesh of the serpent would be a sovereign remedy against the creature's venom: in his book on medicine, Henry of Grosmont, 1st Duke of Lancaster, wrote that "the treacle is made of poison so that it can destroy other poisons". Another rationale for including snake flesh was the widespread belief that snakes contained an antidote to protect themselves against being poisoned by their own venom. Thinking by analogy, Henry Grosmont also thought of theriac as a moral curative, the medicine "to make a man reject the poisonous sin which has entered into his soul." Since the plague, and notably the Black Death, was believed to have been sent by God as a punishment for sin and had its origins in pestilential serpents that poisoned the rivers, theriac was a particularly appropriate remedy or therapeutic. By contrast, Christiane Fabbri argues that theriac actually did have palliative effect against pain and reduced coughing and diarrhea.
History
According to legends, the history of theriac begins with the king Mithridates VI of Pontus who experimented with poisons and antidotes on his prisoners. His numerous toxicity experiments eventually led him to declare that he had discovered an antidote for every venomous reptile and poisonous substance. He mixed all the effective antidotes into a single one, mithridatium or mithridate that contained myrrh, saffron, ginger, cinnamon and castor, along with some forty other ingredients. When the Romans defeated him, his medical notes fell into their hands and Roman medici began to use them. Emperor Nero's physician Andromachus improved upon mithridatum by bringing the total number of ingredients to sixty-four, including viper's flesh, a mashed decoction of which, first roasted then well aged, proved the most constant ingredient. Lise Manniche, however, links the origins of theriac to the ancient Egyptian kyphi recipe, which was also used medicinally.
Greek physician Galen devoted a whole book Theriaké to theriac. One of his patients, Roman emperor Marcus Aurelius, took it on a regular basis.
In 667, ambassadors from Rûm presented the Emperor Gaozong of the Tang dynasty in China with a theriac. The Chinese observed that it contained the gall of swine, was dark red in colour and the foreigners seemed to respect it greatly. The Tang pharmacologist Su Kung noted that it had proved its usefulness against "the hundred ailments."
In the Middle East, theriac was known as Tiryaq, and makers of it were known as Tiryaqi.
In medieval London, the preparation arrived on galleys from the Mediterranean, under the watchful eye of the Worshipful Company of Grocers. Theriac, the most expensive of medicaments, was called Venice treacle by the English apothecaries.
At the time of the Black Death in the mid 14th century, Gentile da Foligno, who died of the plague in June 1348, recommended in his plague treatise that the theriac should have been aged at least a year. Children should not ingest it, he thought, but have it rubbed on them in a salve.
In 1669, the famous French apothecary, Moyse Charas, published the formula for theriac, seeking to break the monopoly held by the Venetians at that time on the medication, thereby opening up the transfer of medical information.
Production
The production of a proper theriac took months with all the collection and fermentation of herbs and other ingredients. It was supposed to be left to mature for years. As a result, it was also expensive and hence available only for the rich.
According to the commentary on Exodus, Ki Tisa, the Spanish scholar Moses ben Nachman lists the ingredients of theriac as leaven, honey, flesh of wild beasts and reptiles, dried scorpion and viper.
According to Galen, theriac reached its greatest potency six years after preparation and kept its virtues for 40 years. It was therefore good practice to make large batches; in 1712, 150 kg of theriac was prepared at one session in Maastricht in the Netherlands.
By the time of the Renaissance, the making of theriac had become an official ceremony, especially in Italy. Pharmacists sold it as late as 1884.
Theriaca Andromachi Senioris
Theriaca andromachi or Venice Treacle contained 64 ingredients. In addition to viper flesh, it included cinnamon, agarics and gum arabic. The ingredients were pulverized and reduced to an electuary with honey.
