John M. Riddle

In Contraception And Abortion From The Ancient World To The Renaissance, Riddle showed that women in ancient times relied on herbs to regulate fertility. In this volume, he shows that this ancient knowledge was not lost, but survived in coded form.

A History of Contraception and Abortion in the West

Eve's Herbs

For 1,600 years Dioscorides (ca. AD 40–80) was regarded as the foremost authority on drugs. He knew mild laxatives and strong purgatives, analgesics for headaches, antiseptics for wounds, emetics to rid one of ingested poisons, chemotherapy agents for cancer treatments, and even oral contraceptives. Why, then, have his works remained obscure in recent centuries? Because of one small oversight (Dioscorides himself thought it was self-evident): he failed to describe his method for organizing drugs by their affinities. This omission led medical authorities to use his materials as a guide to pharmacy while overlooking Dioscorides' most valuable contribution—his empirically derived method for observing and classifying drugs by clinical testing. Dioscorides' De materia medica, a five-volume work, was written in the first century. Here revealed for the first time is the thesis that Dioscorides wrote more than a lengthy guide book. He wrote a great work of science. He had said that he discovered the natural order and would demonstrate it by his arrangement of drugs from plants, minerals, and animals. Until John M. Riddle's pathfinding study, no one saw the genius of his system. Botanists from the eighteenth century often attempted to find his unexplained method by identifying the sequences of his plants according to the Linnean system but, while there are certain patterns, there remained inexplicable incoherencies. However, Dioscorides' natural order as set down in De materia medica was determined by drug affinities as detected by his acute, clinical ability to observe drug reactions in and on the body. So remarkable was his ability to see relationships that, in some cases, he saw what we know to be common chemicals shared by plants of the same and related species and other natural product drugs from animal and mineral sources. Western European and Islamic medicine considered Dioscorides the foremost authority on drugs, just as Hippocrates is regarded as the Father of Medicine. They saw him point the way but only described the end of his finger, despite the fact that in the sixteenth century alone there were over one hundred books published on him. If he had explained what he thought to be self-evident, then science, especially chemistry and medicine, would almost certainly have developed differently. In this culmination of over twenty years of research, Riddle employs modern science and anthropological studies innovatively and cautiously to demonstrate the substance to Dioscorides' authority in medicine.

Dioscorides on Pharmacy and Medicine

Amber and Ambergris in Materia Medica During Antiquity and the Middle Ages

All too often ancient herbal and other remedies have been dismissed as 'simply' folklore, of no relevance to medical science. John Riddle's approach, however, has been to explore the history of drugs with the hypothesis that ancient and medieval medicines were effective - a methodology that he expounds in the final essay (hitherto unpublished). Indeed, he shows, both from detailed case-studies and from the comparison of the listings given by classical and medieval authorities with those in modern pharmacopoeias, that our ancestors had discovered and made effective use of many of the drugs used in medicine today, from antiseptics and analgesics to oral contraceptives, even chemotherapy for cancer. There is the suggestion, therefore, that more careful examination and identification of the drugs used in the past may reveal chemicals that can be exploited anew. Central to these studies is the investigation of how a drug was used and how knowledge about it was transmitted - and perhaps also distorted in the process - from the Classical world through the Middle Ages. Les anciens remèdes, phytothérapie et autres, ont trop souvent été mis aux rangs du folklore et considérés comme n'ayant aucun rapport avec la science médicale. L'approche de John Riddle, cependant, a été d'explorer l'histoire des drogues, en prenant pour hypothèse l'efficacité de la médecine ancienne et médiévale - une méthodologie qu'il expose dans son dernier essai (jusqu'Ã présent jamais publié). En effet, il démontre Ã partir de cas d'études détaillés et de la comparaison établie entre les listages fournis par les autorités antiques et médiévales et ceux des pharmacopées modernes, que nos ancÃatres avaient découvert et mis Ã bon escient l'utilisation de nombreux remèdes dont se sert la médecine Ã l'heure actuelle: des antiseptiques et analgésiques, aux contraceptifs oraux et mÃame jusqu'Ã la chimiothérapie pour le cancer.

Studies in the History of Drugs

Quid Pro Quo

This clear and comprehensive text covers the Middle Ages from the classical era to the late medieval period. Distinguished historian John Riddle provides a cogent analysis of the rulers, wars, and events—both natural and human—that defined the medieval era. Taking a broad geographical perspective, Riddle includes northern and eastern Europe, Byzantine civilization, and the Islamic states. Each, he convincingly shows, offered values and institutions—religious devotion, toleration and intolerance, laws, ways of thinking, and changing roles of women—that presaged modernity. In addition to traditional topics of pen, sword, and word, the author explores other driving forces such as science, religion, and technology in ways that previous textbooks have not. He also examines such often-overlooked issues as medieval gender roles and medicine and seminal events such as the crusades from the vantage point of both Muslims and eastern and western Christians. In addition to a thorough chronological narrative, the text offers humanizing features to engage students. Each chapter opens with a theme-setting vignette about the lives of ordinary and extraordinary people. The book also introduces students to key controversies and themes in historiography by featuring in each chapter a prominent medieval historian and how his or her ideas have shaped contemporary thinking about the Middle Ages. Richly illustrated with color plates, this lively, engaging book will immerse readers in the medieval world, an era that shaped the foundation for the modern world.
