When you're sick, your parents probably take you to the doctor. After examining you, the doctor prescribes medicines. But things were different in ancient times. A sick person was taken to witch doctors, because it was believed that illness was caused by evil spirits. Witch doctors performed magic to exorcise these spirits. If this failed, the witch doctors performed an operation called trepanning, which meant boring a hole through the skull so that the evil spirits trapped in the body, would escape. This was the primitive way practiced in many parts of the world.
However, discoveries and innovations in medical science have changed everything.
This issue of Tell Me Why features breakthroughs in medical science.
