Pharmacognosy is the branch of pharmacology that focuses on the study of natural products, particularly those derived from plants and other living organisms. It involves the identification, extraction, and analysis of bioactive compounds that can be used for medicinal purposes. This field plays a crucial role in discovering new drugs and understanding the therapeutic properties of traditional remedies. Researchers in pharmacognosy explore various sources, including herbs, spices, and marine organisms, to find substances that can treat diseases. By studying these natural compounds, scientists aim to develop effective medications while also ensuring safety and efficacy in their use.
