Pedanius Dioscorides
Materia medica (lit.: 'medical material/substance') is a Latin term from the history of pharmacy for the body of collected knowledge about the therapeutic properties of any substance used for healing (i.e., medicines). The term derives from the title of a work by the Ancient Greek physician Pedanius Dioscorides in the 1st century AD, "De materia medica", 'On medical material' (Περὶ ὕλης ἰατρικῆς, "Peri hylēs iatrikēs", in Greek).
