Greek Medicine refers to the medical practices and theories developed in ancient Greece, primarily from the 5th century BCE to the 2nd century CE. It is characterized by a shift from supernatural explanations of disease to more naturalistic approaches, emphasizing observation and rational thought. Key figures include Hippocrates, often called the "Father of Medicine," who advocated for ethical standards and systematic clinical observation. Another significant contributor was Galen, whose extensive writings on anatomy and physiology influenced medical understanding for centuries. Greek Medicine laid the groundwork for modern medical practices, introducing concepts such as the four humors and the importance of diet and lifestyle in health.
