Our Ancestors conducted brain surgeries since over thousands of years ago done mostly by a Herbalist which the Europeans called Witch doctors cause they never understood the science of using herbs.
The patient was given lots of alcohol, then pinned down by people and the herbalist will split their skull and remove the tumor from the brain. Then cover the gape with herbs and bind the skull together with ropes made from palm fronds. Patient heals over some weeks. #Africa
