Pharmacognosy is the study of plants and other natural substances as possible sources of drugs. The American Society of Pharmacognosy characterizes pharmacognosy as "the study of the physical, chemical, biochemical, and organic properties of medicines, drug substances, or potential drugs or drug substances of natural origin as well as the quest for new drugs from regular sources.

It is accepted that the human body finds plant-inferred drugs more straightforward to acknowledge because of the way that they exist in nature and are not engineered. Around 25% of doctor prescribed medications in the USA are accepted to have a functioning fixing from a characteristic source. In emerging nations, it's assessed that around 80% of their populaces depend on customary drugs produced using plants and spices [1-2].

Plants and living beings are utilized in an assortment of courses in the creation of customary and elective drugs. The valuable dynamic element of the plant might be tracked down anyplace in its actual design, for example, in the petal or stem of a bloom.

The natural product may be dormant in its typical actual structure, so it might take a synthetic response or change to bring it into its dynamic structure. Now and again, the dynamic fixing is removed straightforwardly from the plant, however on different events the dynamic fixing can be delivered through union by making a compound that acts much the same way to the plant separate [3].

At the point when the expression "natural product" is referenced, they can be simply the living being (plant, creature, and microorganism), any piece of an organic entity (a leaf or bloom of a plant, a segregated organ or other organ of a creature), and concentrate or unadulterated substances. Certainly, plants are productive wellsprings of new bioactive synthetics, for example, atropin, ephedrine, morphine, caffeine, salicylic corrosive, digoxin, taxol, galantamine, vincristine, colchicine, and so on Indeed, around 25% of the professionally prescribed drugs administered in the United States contain no less than one dynamic element of plant origin [4]. Consequently, natural products or mixtures are as yet drawing in an incredible consideration from researchers. Plants, yet in addition different creatures including marine creatures, insects, frogs, worms, and so forth as well as microorganisms produce vital medication applicant atoms. For example, the antecedent of acyclovir, the strong antiviral medication, was right off the bat found in a marine wipe and afterward formed into an antiviral drug. Apicidin confined from the microorganism Fusarium pallidoroseum (Costa Rica) has been accounted for to be a contagious metabolite with intense wide range antiprotozoal movement in vitro and adequacy against jungle fever factor Plasmodium berghei.

A few mixtures are utilized as dynamic fixings in the structure straightforwardly separated from plant extricates; others are orchestrated to mirror a characteristic plant compound. Consequently, regular mixtures could be great models for creating novel drug particles [5]. Demonstrating or adjusting is a significant activity for drug industry. Since now and again, natural products apply close to nothing or even no movement themselves; however by alteration and utilizing compound or organic strategies, intense medications can be created. A genuine model for this case could be baccatin III detached from Taxusbaccata (yew tree), which is adjusted into taxol, a powerful anticancer drug.
