Pharmacognosy is the branch of pharmacology that deals with the study of natural products and their medicinal properties. It is the science of identifying, selecting, and using natural products such as plants, animals, and minerals for therapeutic purposes. The term “pharmacognosy” is derived from the Greek words “pharmakon” meaning drug and “gnosis” meaning knowledge.

Pharmacognosy involves the study of various aspects of natural products, including their physical and chemical properties, their biological activity, and their potential as sources of new drugs. It is also concerned with the standardization, quality control, and safety of natural products used in medicine.

Some of the natural products studied in pharmacognosy include medicinal plants, herbs, fungi, marine organisms, and animal products. Pharmacognosists use a variety of techniques and tools to study these natural products, such as chromatography, spectroscopy, and microscopy.

The field of pharmacognosy has contributed significantly to the development of modern medicine, with many important drugs derived from natural sources. For example, morphine, quinine, and aspirin were all originally derived from natural sources.

Pharmacognosy continues to be an important area of research today, with scientists exploring the potential of natural products to treat a wide range of diseases, including cancer, School Analytics, infectious diseases, and neurological disorders. It also plays a key role in the development of new drugs and in the search for more sustainable and environmentally-friendly sources of medicine.
