‘Pharmacognosy’—has been coined by the merger of two Greek words Pharmakon (drug) and Gnosis (knowledge) i.e., the knowledge of drugs. The nomenclature—‘Pharmacognosy’ was used first and foremost by C.A. Seydler, a medical student in Halle/Saale, Germany, who emphatically employed Analetica Pharmacognostica as the main title of his thesis in the year 1815. Besides, further investigations have revealed that. Schmidt has made use of the terminology ‘Pharmacognosis’ in the monograph entitled Lehrbuch der Materia Medica (i.e., Lecture Notes on Medical Matter) which dates back to 1811, in Vienna. This compilation exclusively deals with the medicinal plants and their corresponding characteristics.
