materia medica
Δύο γὰρ, ἐπιστήμη τε καὶ δόξα, ὧν τὸ μὲν ἐπίστασθαι ποιέει, τὸ δὲ ἀγνοεῖν → Two different things are science and belief: the one brings knowledge, the other ignorance (Hippocrates)

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).
The term materia medica was used from the period of the Roman Empire until the 20th century, but has now been generally replaced in medical education contexts by the term pharmacology. The term survives in the title of the British Medical Journal's "Materia Non Medica" column.
