Abstract
The word pharmacognosy consists of two Greek words, which mean drug and knowledge. In this field of science, researcher deals with the secondary metabolites found in many plants, animals, and microbial natural sources, for example, plant leaves, seeds, fruits, stem, roots, rhizosphere, herbs, spices, fungus, algae, corals, star fishes, jelly fishes, sponges, sea cucumber, sea urchins, sea weeds, snakes venom, frogs skin, cockroaches, and many more. The American Society of Pharmacognosy (ASP) defines it as “the study of the physical, chemical, biochemical and biological properties of drugs, drug substances, or potential drugs or drug substances of natural origin as well as the search for new drugs from different natural sources” [1]. Most of the countries in South-East Asia Region of the WHO (World Health Organization) have a heritage of traditional medicine system. According to the recent WHO report, about 80% of world population is still using natural product for their primary healthcare needs. Pharmacognosy can provide safe and effective drugs in combination with modern medicine system.
