Compound Remedies examines the equipment, books, and remedies of colonial Mexico City’s Herrera pharmacy—natural substances with known healing powers that formed part of the basis for modern-day healing traditions and home remedies in Mexico. Paula S. De Vos traces the evolution of the Galenic pharmaceutical tradition from its foundations in ancient Greece to the physician-philosophers of medieval Islamic empires and the Latin West and eventually through the Spanish Empire to Mexico, offering a global history of the transmission of these materials, knowledges, and techniques.
