Of the China root: a case study of the early modern circulation of materia medica

The early modern rise of syphilis provoked similar anxieties to those that more recently accompanied the global spread of HIV/AIDS. It also stimulated global demand for remedies. I discuss one of the most popular, known as ‘China root’ and usually identified with various species of Smilax. The drug and instructions for its use were spread westward from China by traders of all nationalities from 1535 onwards. Demand became global before being largely replaced in Europe by supplies of various American Smilax species, known collectively as ‘Sarsaparilla’. I examine the economic, political and cultural dynamics of this process and draw from them some conclusions about the early modern drugs trade and its effects on medical thought
