Roman medicine was influenced by earlier practices from the Greeks and Etruscans. Physicians, known as medici, used a combination of herbal remedies, surgical techniques, and the study of anatomy to treat patients. They emphasized the importance of diet and hygiene in maintaining health. The Roman Empire established military hospitals and public health systems, including aqueducts for clean water and sewage systems for sanitation. Notable figures like Galen advanced medical knowledge through their writings, which remained influential for centuries. Despite their advancements, Romans still relied on superstitions and rituals in their medical practices.
