2. HISTORY OF PHARMACOGNOSY
The word “PHARMACOGNOSY” had been derived from two Greek
words, “Pharmakon” meaning drug and “Gnosis” meaning
knowledge
It is defined as the study of physical, chemical, biochemical, and
biological properties of drugs, drug substances of natural origin.
In other words, it is also defined as the study and research of crude
drug.
Although most pharmacognostic studies focus on plants and
medicines derived from plants, other types of organisms are also
regarded as pharmacognostically interesting, in particular, various
types of microbes (bacteria, fungi, etc.), and, recently, various
marine organisms.
