👉 In pharmacology, an apothecium is a type of drug preparation that contains active ingredients in a concentrated form. It was first described by the French pharmacologist Jean-Baptiste Lamarck in his 1754 work "L'Anatomie des Herbes" (The Anatomy of Plants). The term has since been widely used in modern medicine and pharmacy to refer to any type of preparation, including pills, powders, solutions, syrups, etc.
