  • Pharmacognosy is the study of natural substances, primarily plants, used in medicine.
  • It's considered an applied science examining the biological, biochemical, and economic aspects of natural drugs and their components.
  • It's the study of drugs originating from plants and animals.
  • The term "pharmacognosy" was first used in Germany in 1815 by a medical student named Seydler.
  • It combines the Greek words "pharmakon" (drug) and "gnosis" (knowledge).
