Pharmacognosy is a branch of allopathic medicinal system and drugs are not supposed to be used as whole or in some direct processed forms (extract or powdered), it aims for the study of active constituents and metabolites that are responsible for the physiological activity as well as the drug used for the preparation of other pharmaceutical products such as additives, flavoring agents, sweeteners, bitters, perfumes etc.

pharmacognosy literally means (Greek words)phramakon+ gignosko = the drug + to acquire the knowledge of - to acquire the knowledge of drug.

Most of drugs used today is or either derived from substances that we first found in plants. From the willow bark we got salicylic acid that we could makes aspirin from. And then we used that knowledge to makes new drugs, as ibuprofen, diclofenac or etc.
