Pharmacognosy Book By Tyler Pdf 17
The term \"pharmacognosy\" was coined by Anotheus Seydler, a German botanist, from the two Greek words \"pharmakon\", meaning drug or medicine, and \"gnosis\", meaning knowledge. Even today, about a quarter of all prescription drugs in the United States have one or more bioactive compounds derived from plants.
According to the American Society of Pharmacognosy, the definition of pharmacognosy is \"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 natural sources.\"
Pharmacognosy involves botanical knowledge to classify and name the plant and understand its genetic pattern and its cultivation. Chemical knowledge is also important in this field for isolating, identifying, and quantitatively assessing the bioactive compounds in the plant sources. Finally, pharmacology plays a role in pharmacognosy, as it allows for researchers to detect and evaluate the biological properties of plants and determine their effects on living systems.
Traditionally, pharmacognosy was recognized as a vital part of drug development processes and pharmacy education; however, the advent of new miracle drugs that can be synthesized in the laboratory led to a decline in its practice.
The respect for ancient wisdom is reflected in the form of phytotherapy and phytopharmaceuticals. The use of plant products to treat illnesses is well known in South American nations, China and India, where billions of dollars are spent on pharmacognosy research to identify and market natural medicinal drugs.
