Scope of Pharmacognosy 20th Century important drugs discover from the animal kingdom during the century micro organisms have become essential source of drugs. 21th Century Chemsitry & genetics were Applied in plants to produce new plant & herb varieties. Scope of Pharmacognosy for isolation, extraction and development of new chemicals from medical plants was increased by the introduction of new branches. Pharmacognosy as an applied science has played an important role in developing different disciplines of science. Scope of pharmacognosy discussed below  Synthesis drugs and antibiotics : The demand of pharmaceutical production of plant orgin has increased due to the world wide use of synthesis drugs and antibiotics.  InIndigenous system of medicine : Plants lants synthesis biologically active secondary metabolism due to which they called a Chemical laboratory. Based on the availability of medicinal plants as raw material ,the who has emphased to utilization of indigenous system of medicine.  Herbal medicine : Since herbal medicine do not have any toxic or side effects they have gainted popularity in the recent year.  Medicinal plant : Medicinal Plants are found disturbed in almost all part of india, there it is richest so use of medicinal plant.  Plant Drugs and remedies : Complex omplex diseases like cancer AIDS are treated by plant drugs and remedies , Which are safer than the Synthetic medicines.
