=== East Africa ===
European travelers in the Great Lakes region of Africa during the 19th century reported cases of surgery in the kingdom of Bunyoro-Kitara. Medical historians, such as Jack Davies argued in 1959 that Bunyoro's traditional healers were perhaps the most highly skilled in precolonial sub-Saharan Africa, possessing a remarkable level of medical knowledge. One observer noted a "surgical skill which had reached a high standard". Caesarean sections and other abdominal and thoracic operations were performed on a regular basis with the avoidance of haemorrhage and sepsis using antiseptics, anaesthetics and cautery iron. The expectant mother was normally anesthetized with banana wine, and herbal mixtures were used to encourage healing. From the well-developed nature of the procedures employed, European observers concluded that they had been employed for some time. Bunyoro surgeons treated lung inflammations, Pneumonia and pleurisy by punching holes in the chest until the air passed freely. Trephining was carried out and the bones of depressed fractures were elevated. Horrible war wounds, even penetrating abdominal and chest wounds were treated with success, even when this involved quite heroic surgery. Amputations were done by tying a tight ligature just above the line of amputation and neatly cutting off the limb, stretched out on a smooth log, with one stroke of a sharp sword. Banyoro surgeons had a good knowledge of anatomy, in part obtained by carrying out autopsies. Inoculation against smallpox was carried out in Bunyoro and its neighbouring kingdoms. Over 200 plants are used medicinally in eastern Bunyoro alone and recent tests have shown that traditional cures for eczema and post-measles bloody diarrhoea were more effective than western medications. Bunyoro's Medical elite, the "Bafumu", had a system of apprenticeship and even "met at periods for conferences". In Bunyoro, there was a close relationship between the state and traditional healers. Kings gave healers "land spread in the different areas so that their services would reach more people". Moreover, "in the case of a disease hitting a given area", the king would order healers into the affected district. Kabaleega is said to have provided his soldiers were anti-malarial herbs, and even to have organized medical research. A Munyoro healer reported in 1902 that when an outbreak of what he termed sleeping sickness occurred in Bunyoro around 1886–87, causing many deaths, Kabaleega ordered him "to make experiments in the interest of science", which were "eventually successful in procuring a cure". Barkcloth, which was used to bandage wounds, has been proven to be antimicrobial.
Brain surgery was also practiced in the Great Lakes region of Africa
In the Kingdom of Rwanda, people afflicted with Yaws were put into quarantine and if necessary, kings closed the kingdom's borders to combat the spread of smallpox.

=== Central Africa ===
General and local anesthesia were widely used by traditional doctors in many parts of central Africa. Beer containing an extract of kaffir was orally given to those who sustained deep wounds from animal attacks or from warfare in order to alleviate pain, and alkaloid containing leaves were also applied topically to injuries. Many tribes in central Africa performed cataract surgery under local anesthesia, squeezing juices from alkaloid plants directly into the eyes to desensitize them and then pushing the cataract aside with a sharp stick, with many cases turning out successful. "The surgical skill itself was also astonishing and suggested a long experience of this practice".
