From rustics to savants: indigenous materia medica in eighteenth-century Mexico.

This essay explores how indigenous knowledge about plant and animal remedies was gathered, classified, tested, and circulated across wide networks of exchange for natural knowledge between Europe and the Americas. There has been much recent interest in the "bioprospecting" of local natural resources-medical and otherwise-by Europeans in the early modern world and the strategies employed by European travellers, missionaries, or naturalists have been well documented. By contrast, less is known about the role played by indigenous and Creole intermediaries in this process. And yet, the transmission of knowledge between indigenous communities and the European cabinet was neither transparent nor natural, and often involved epistemological, linguistic, and religious obstacles. Drawing on printed and manuscript collections of indigenous remedies, written in colonial Mexico between the sixteenth and the eighteenth centuries, I focus on how local intermediaries, like creoles scholars, sought to overcome such obstacles by observing indigenous uses of remedies, by studying indigenous languages and by producing natural histories and pharmacopoeias in indigenous languages. Ultimately, behind the Creole participation in the transmission of indigenous remedies, one can point to political and cultural interests and to inclusive definitions of knowledge, which cut across oppositions between science and superstition, cabinet and field, centre and periphery.

[Protomedicato and pharmacy in Castile at the end of the sixteenth century: "Catálogo de las Cosas que los Boticarios han de tener en sus Boticas" (Catalogue of the things that apothecaries must have in their shops), by Andrés Zamudio de Alfaro, Protomédico General (1592-1599)]. / Protomedicato y farmacia en Castilla a finales del siglo XVI: edición crítica del "Catálogo de las Cosas que los Boticarios han de tener en sus Boticas," de Andrés Zamudio de Alfaro, Protomédico General (1592-1599).

In this article we present a catalogue of medicinal products preserved in a manuscript copy among the papers of a druggist who died in Madrid in 1599. This catalogue, whose title expresses its normative character, contains 423 entries and is signed by Andrés Zamudio de Alfaro, Protomédico General of Castile from 1592 until his death in 1599. It was presumably issued by the Real Tribunal del Protomedicato during the last decade of the sixteenth century for the use of the protomédicos and examiners who carried out official visits to apothecaries under the aegis of the Tribunal, in accordance with the royal decrees of 1588 and 1593, and was also distributed among the apothecaries themselves and their suppliers, such as the druggist who possessed the copy edited here. The document offers valuable evidence of the policy of normalization of medical, and specifically pharmaceutical, practice imposed during this period by the State through the Protomedicato.

Arsenic: a beneficial therapeutic poison - a historical overview.

Arsenicals have been used since ancient Greek and Roman civilizations and in the Far East as part of traditional Chinese medicine. In Western countries, they became a therapeutic mainstay for various ailments and malignancies in the 19th and early 20th centuries. Fowler's potassium bicarbonate-based solution of arsenic trioxide (As2O3)solution was the main treatment of chronic myeloid leukaemia until the 1930s. After a decline in the use of arsenic during the mid-20th century, arsenic trioxide was reintroduced as an anticancer agent after reports emerged from China of the success of an arsenic trioxide-containing herbal mixture for the treatment of acute promyelocytic leukaemia. Arsenic trioxide was first purified and used in controlled studies in China in the 1970s.Subsequently, randomised clinical trials performed in the United States led to FDA approval of arsenic trioxide in the treatment of patients with relapsed or refractory acute promyelocytic leukaemia.
