The pharmacist's trade dates back hundreds of years. For centuries apothecaries, the forerunners of modern pharmacists, weren't only responsible for mixing and selling medicines, but also for diagnosing illnesses and even for performing surgery and delivering babies!
In the 1800’s the profession of the modern pharmacist emerged as the maker and dispenser of medicines, after doctors had taken over the apothecary's former roles. A mortar and pestle were essential tools for a pharmacist to grind ingredients to be combined into medicines. Leeches were a common tool to drain away "bad blood"; even into the 19th century.
