Pharmacology has developed from observations of natural remedies into a scientific discipline that studies how chemicals affect the body. Understanding this history helps explain how modern medicines emerged and why evidence, safety, and careful study matter.
The word pharmacology comes from the Greek pharmakon, meaning “drug” or “medicine,” and logos, meaning “study.” Pharmacology is the study of medicines and, more broadly, of the biological effects of chemicals on the body. The terms drug and medication are often used interchangeably.
