Throughout all of antiquity, from the Stone Age to the Islamic period, the doctors of Egypt were the best in the Western world, though there were also very good doctors in India and China. But that isn't really saying very much: nobody in the ancient world really understood what caused diseases or how to cure them.
Egyptian doctors mostly believed that evil spirits either got inside your body or sent poisons inside your body to make you sick. To cure you, the doctors made you eat or drink something very nasty-smelling. They hoped the evil spirit wouldn't like the smell and would leave your body. Or the doctors tried to clean your insides out to get rid of the poison, by giving you laxatives or bleeding you. And they prayed to Sekhmet, the goddess of healing. To cure a cold, they gave you human breast milk to drink. These magic things could really help you, because often people get better when they just see the doctor doing something.
Egyptian doctors did also use effective medical treatments. They massaged aching legs and calves, they stitched and bandaged wounds, and they set broken and dislocated arms and legs. Specialized dentists pulled infected teeth and built bridges to replace lost teeth. Midwives helped women with childbirth. Egyptian doctors used powdered charcoal as a medicine to absorb poisons and cure food poisoning (as we still do today), and they put powdered charcoal on wounds to absorb pus and blood and promote clotting.
But Egyptian doctors couldn't do anything about schistosomiasis, which probably contributed to the deaths of many if not most Egyptians. Malaria and tuberculosis also weakened or killed many people, and Egyptian doctors also couldn't treat those.
The biggest contribution of Egyptian doctors to medicine was their research on how the human body worked. They figured out that your pulse was related to your heart-beat. They learned that your bronchial tubes ran under your collarbones, from your throat to your lungs. Egyptian doctors continued to be leaders in medical research through the Hellenistic period and the Roman period into the Islamic period, culminating in the work of the great doctor Maimonides.
Learn by doing: feel your pulse and see if it beats faster when your heart beats faster.
