Jewish Medicine Concentrated on health rules for food, cleanliness, and quarantine. Biblical Times: Moses studied hygiene and medicine at the temple of Egypt. Moses banned quackery (trickery) because God was the only physician. Thought of the “day of rest” was best for human welfare.

Greek Medicine First to study causes of diseases Research helped eliminate superstitions Sanitary practices were associated with the spread of disease Hippocrates-Father of Medicine no dissection, only observations took careful notes of signs/symptoms of diseases disease was not caused by supernatural forces wrote standards of ethics which is the basis for today’s medical ethics (Hippocratic Oath)
