In 1796, Edward Jenner administered the world’s first vaccine in rural England, and the history of medicine changed forever. At least, that is the version of events taught in every Western classroom. What those classrooms never mention is that an enslaved West African man named Onesimus had already described the same principle to a Boston minister roughly 75 years before Jenner ever picked up a lancet.
Onesimus was not the only example. Historical records from places such as Egypt, Uganda, Nigeria, and Madagascar show that African practitioners developed surgical procedures, herbal treatments, bone-setting methods, and approaches to mental health long before many similar practices became established in Europe. When the West finally “discovered” these breakthroughs, the African origins were quietly erased and replaced by the names of European men who received the credit.
Apart from gold, diamonds, land, and labour, Africa’s intellectual history was also stolen. Today, pharmaceutical companies extract billions of dollars from African plant compounds while the communities that first identified their healing properties see nothing in return. The rosy periwinkle of Madagascar generates hundreds of millions of dollars a year in cancer drug revenue, yet Madagascar remains one of the poorest countries on earth.
Here are the medical technologies Africa had before Western medical text books were written to erase their African origins.
Vaccination: An African Practice Centuries Before Jenner
The conventional narrative credits Edward Jenner with inventing vaccination in 1796 and places the entire origin story in the English countryside. The actual history starts on the west coast of Africa, in the region that is now Ghana.
Onesimus, an Akan man taken from the region around Kormantse in present-day Ghana, was enslaved in Boston around 1706. He became the property of Cotton Mather, one of the most influential Puritan ministers in the Massachusetts colony. In 1716, Mather asked him whether he had ever had smallpox. Onesimus explained that he had undergone an inoculation procedure in Africa that protected him from the disease. The method involved placing material from a smallpox sore into a cut on the skin. Most patients developed a mild infection and later became immune. Onesimus told Mather the practice was common in parts of West Africa.
Mather later spoke to other enslaved Africans who described the same procedure, which was commonplace across West Africa. He found that the practice known today as variolation, had deep roots in African and Asian medical traditions. During Boston’s smallpox epidemic in 1721, he persuaded physician Zabdiel Boylston to test the method. Boylston inoculated around 240 people, and only six died, which was a mortality rate of about 2.5%, compared to 14.3% of those who were not inoculated.
Although the results were extraordinary, Boston’s white establishment attacked the idea precisely because it came from an African. James Franklin, Benjamin Franklin’s older brother, ran a newspaper campaign ridiculing Mather for taking medical advice from an enslaved man. Critics accused Africans of trying to poison white people. The racial hostility was so severe that someone threw a firebomb through Mather’s window.
Jenner later developed vaccination using cowpox rather than smallpox material, and his work became central to the European history of immunization. A tomb inscription even credits Boylston as the “first” to introduce inoculation in America. Onesimus was largely left out of the story, and historical records suggest that he eventually bought part of his freedom, though little is known about the rest of his life. Smallpox was declared eradicated in 1980, and it remains the only human infectious disease eliminated through global immunization.
Caesarean Surgery: Routine in Uganda, Deadly in Europe
In 1876, an Italian surgeon named Edoardo Porro performed what is often cited as the first successful caesarean section in Europe—a procedure that, even then, was considered nearly suicidal for the mother. Three years later, a young Scottish medical student named Robert Felkin witnessed something in the kingdom of Bunyoro-Kitara, in modern-day Uganda, that shattered everything Europeans believed about African medicine.
Felkin described the operation as one with a high level of precision and calm. The healer used banana wine to sedate the patient and clean the surgical area and his hands. Joseph Lister had introduced antiseptic surgery in Europe in 1867, but infection remained a major problem in many European hospitals by the late 1870s. The healer made a clean midline incision through the abdominal wall and uterus, cauterized bleeding with a red-hot iron, removed the child and the placenta, then closed the wound with seven iron pins and dressed it with a paste made from local roots. The mother breastfed her child two hours after the operation. By the eleventh day, the wound had healed entirely.
Felkin believed the procedure was already established practice in Bunyoro, long before any European set foot in the region, since it was so rehearsed and standardized. The kingdom had been isolated from outside contact until the mid-nineteenth century. The first foreigners to reach Bunyoro came from Zanzibar in 1852, and the first Europeans arrived just seventeen years before Felkin's visit, in 1862.
While Felkin was writing up his notes, surgeons in London and Edinburgh were still debating whether a caesarean section could ever be justified on a living woman. At the same time, many European hospitals were still struggling with post-operative infection during caesarean procedures. Antiseptic methods were only beginning to spread through European medicine, and surgical mortality remained high. In Bunyoro, the problems of antisepsis had already been worked out using locally grown materials.
Felkin published his observations in the Edinburgh Medical Journal in 1884. The knife associated with the procedure is now held in the Science Museum in London.
The World’s Oldest Surgical Textbook Was African
Histories of the birth of rational medicine often begin with Hippocrates, the Greek physician born around 460 BCE. But the Edwin Smith Papyrus, written in ancient Egypt around 1600 BCE and likely copied from a text dating to 3000 BCE, puts African evidence-based medicine more than a thousand years before Hippocrates.
The Edwin Smith Papyrus is the oldest known surgical text in human history. It describes 48 cases of traumatic injury, arranged systematically from head to torso. Each case follows a structured method. The physician examines the patient, describes the injury, gives a diagnosis, and recommends treatment. Some cases are marked as treatable conditions, others are conditions he will attempt to fight, or conditions that cannot be healed. That three-tier judgment is the same logic emergency doctors use today when a mass casualty event overwhelms a hospital.
The treatments were practical and direct. Physicians stitched wounds with linen sutures and stabilized fractures with splints. Honey was used on wounds, a method now known to help prevent infection. The papyrus also contains the first known descriptions of the cranial sutures, the meninges, the external surface of the brain, and cerebrospinal fluid. It records that injuries to different parts of the brain produce symptoms in different parts of the body. That observation would not resurface in European medicine for another three thousand years.
Unlike many surviving medical texts from the ancient world, the Edwin Smith Papyrus is almost completely empirical. The text relies mostly on observation and physical examination rather than magic and superstition. Magic appears in only one of the 48 recorded cases.
Africa’s Pharmacy: Plants That Built Modern Medicine
If you have ever taken a chemotherapy drug, you may owe your life to a small pink flower from Madagascar. The rosy periwinkle, Catharanthus roseus, is native and endemic to the island. For centuries, Malagasy healers used infusions of its leaves and roots to treat a variety of ailments. During the era of the Swahili trade, roughly 800 to 1450 CE, the plant was carried across the Indian Ocean by sailors who transported cuttings along trade networks linking Madagascar to East Africa, the Arabian Peninsula, and Southeast Asia.
In the 1950s, Western researchers, set out to test the plant as a treatment for diabetes, discovered compounds that affected white blood cell production. The discovery led to the development of vincristine and vinblastine, two drugs that became important in cancer treatment. Vincristine helped transform survival rates for childhood leukemia, from under 10 percent in 1960 to roughly 90 percent today. Vinblastine became widely used in the treatment of several cancers, including Hodgkin lymphoma and breast cancer. Both medicines are now listed by the World Health Organization as essential medicines.
The pharmaceutical companies that developed these drugs patented them without compensation to Madagascar or to the healers whose knowledge had first pointed to the plant's value. Madagascar remains one of the poorest countries on earth. The companies that built billion-dollar cancer drug lines from its endemic flora paid nothing back.
The periwinkle was not the only case. Traditional healers in several African regions used Prunus africana to treat urinary problems long before European companies began selling extracts from its bark for prostate conditions. In 1966, European researchers confirmed the bark's effectiveness against benign prostatic hyperplasia. By the 1970s, French and Italian pharmaceutical companies were harvesting it at industrial scale. By 1995, the species had been listed under CITES Appendix II as endangered. Demand for the bark later contributed to overharvesting in parts of Central Africa.
Another example is Pelargonium sidoides, a plant used in South African herbal medicine for respiratory illness. Extracts from the root became the basis for cold and bronchitis remedies sold in Europe under brand names such as Kaloba and Umcka. Patents were filed at the European Patent Office. Indigenous groups in South Africa have challenged those patents on the grounds that the extraction methods duplicate prior traditional knowledge.
Bone-Setting: The Original Orthopaedics
The field of orthopaedics was formally named in 1741, when the French physician Nicolas Andry published his landmark book on correcting musculoskeletal deformities in children. Long before that, bone-setters across many African societies were already treating broken limbs and joint injuries.
Among the Yoruba in present-day Nigeria, bone-setters held an important place in traditional medicine. They were the primary option for fracture treatment long before Western-style hospitals arrived in Lagos in the late nineteenth century. Today, in a country of over 200 million people, there are fewer than 400 orthopaedic surgeons. More than 85 percent of fracture patients still present first to traditional bone-setters.
In parts of East Africa, healers are documented in ethnographic literature as having performed amputations of severely damaged limbs and fashioning prostheses for patients afterward. In Bunyoro-Kitara, the same kingdom where Felkin watched the caesarean section, healers treated trauma as a whole, managing pain and setting bones as part of the same care.
Traditional bone-setters used splints from bamboo or palm leaf, bound with cloth. The bone-setter assessed the injury by feel, set it by hand, immobilised it, and applied herbal preparations to bring down swelling. The knowledge passed through families, usually over years of apprenticeship.
Traditional bone-setters still treat many fracture patients in parts of Africa today, especially in areas with limited access to orthopaedic surgeons. The WHO has called for closer cooperation between bone-setters and formal hospital systems rather than treating them as separate worlds.
Holistic Mental Health: Community Healing Before Psychiatry Existed
Long before psychiatry became a formal medical field in Europe and North America, many African societies already had established ways of treating mental distress. In many communities, mental illness was understood as something connected to spiritual imbalance or social isolation. Where Western psychiatry historically isolated patients in institutions, African healing often involved relatives and local healers rather than separating the patient from community life.
Healers used different approaches depending on the region. Some relied on counselling, ritual, music, herbal remedies, or mediation between family members. In many cases, the goal was to restore social balance alongside the patient’s mental health.
The Nigerian psychiatrist Thomas Adeoye Lambo studied the relationship between African healing systems and Western psychiatry during the twentieth century. Beginning in 1954 at the Aro Hospital for Nervous Diseases near Abeokuta, he developed what became known as the Aro Village model. Patients were boarded in surrounding villages rather than locked in wards, accompanied by family members who cooked for them and maintained their daily routines. Traditional healers worked alongside clinical staff. Recovery rates at Aro were demonstrably better than those in the colonial asylum system that preceded it. He argued that patients often responded better when treatment reflected their own cultural environment and support systems.
Modern mental health care has increasingly moved toward community-based treatment and family involvement. For decades, the same establishment dismissed African healing traditions as superstition. In South Africa, colonial legislation such as the Medical, Dental and Pharmacy Act of 1928 subordinated and heavily restricted traditional healing practices under Western medical authority. Lambo’s Aro Village model became an influential case study in transcultural and community psychiatry.
Hydrotherapy: Water as Medicine
Traditional African societies also practised hydrotherapy—the therapeutic use of water in various temperatures and forms. Cold baths, hot baths, and steamed vapour treatments were used to treat fever, headaches, rheumatism, and general pain. The practice worked by relaxing the skin’s capillaries, increasing the activity of sweat glands, improving circulation, and facilitating the elimination of toxins.
Hydrotherapy was documented across multiple African communities well before it was systematized in European medicine during the nineteenth century. European practitioners like Vincent Priessnitz and Sebastian Kneipp are typically credited with pioneering water-based therapies in the 1820s and 1850s respectively. African communities had been using these methods for generations by then—without the credit and without the spa resorts.
The Cost of Erasure
Colonial governments often dismissed African healing practices as superstition or illegal medicine. In 1953, the Medical Association of South Africa outlawed cooperation between conventional doctors and traditional healers. In 1957, the Witchcraft Suppression Act criminalised many traditional healing practices outright, forcing them underground across the country.
In many places, that disruption affected how medical knowledge was passed between generations. Some practices survived through oral teaching and apprenticeship. Others declined as older healers died without recording their methods.
Researchers are still studying African medicinal plants used in local healing traditions. Some have already produced globally important medicines, including cancer treatments derived from the Madagascar periwinkle and prostate drugs linked to Prunus africana. At the same time, many communities connected to that knowledge continue to receive little benefit from the industries built around those products.
The World Health Organization has increasingly encouraged member states to study and regulate traditional medicine alongside formal healthcare systems. In many African countries, traditional healers still serve large populations with limited access to hospitals and specialists. In May 2025, the 78th World Health Assembly formally adopted the WHO Global Traditional Medicine Strategy 2025–2034. The strategy calls for evidence-based integration of traditional medicine into national health systems and stronger protections for Indigenous knowledge.
Onesimus shared the practice of smallpox inoculation in colonial Boston more than three centuries before the World Health Organization formally adopted a strategy to protect traditional medical knowledge. The distance between those moments says something about how long African medical knowledge has been used without equal recognition.
