From Wikipedia, the free encyclopedia

Prehistoric medicine is a term used to describe the use of medicine before the invention of writing. As the timing of the invention of writing varies per culture and region, the term "prehistoric medicine" encompasses a wide range of time periods and dates.[1]

The study of prehistoric medicine relies heavily on artifacts and human remains, and on anthropology. Previously uncontacted peoples and certain indigenous peoples who live in a traditional way have been the subject of anthropological studies in order to gain insight into both contemporary and ancient practices.[2]

Beliefs and ideas on disease

It is clear that prehistoric societies believed in both natural and supernatural means of variably causing and treating disease.[3][4][5] For serious or disabling diseases, for which there was no rational cause, blame was placed on the supernatural—gods, evil spirits and sorcery.[6] It was believed that evil spirits, conjured by a sorcerer, could inhabit a person's body and cause illness and that these spirits could be removed from the patient, through the skull, by trepanning, and through other treatments carried out by a shaman, a medicine man.[3]

Logic and reasoning were used to deduce the cause of injuries. Injuries, for which there was a clear cause, were not blamed on the supernatural.[7]

In 1991 in the Tyrolean Alps in Northern Italy, the discovery of a mummified body suggested that prehistoric societies may have had greater medical knowledge than had previously been thought. The body, that came to be known as Ötzi the Iceman, contained in his possessions a fungus that scientists found could kill internal parasites; in a Lancet study which followed, Dr. Luigi Capasso concluded that "the discovery of the fungus suggests that the Iceman was aware of his intestinal parasites and fought them with measured doses of Piptoporus betulinus."[4] Although the Iceman may not have had a detailed understanding of intestinal parasites, the findings further imply that prehistoric societies were willing to accept and apply practical outlooks on disease.

Disease and mortality

Different diseases and ailments were common in prehistory than are prevalent today; there is evidence that many people suffered from osteoarthritis, probably caused by the lifting of heavy objects which would have been a daily and necessary task in their societies. The transport of, for example, latte stones, involving hyperextension and torque of the lower back, while dragging the stones, may have contributed to the development of microfractures in the spine and subsequent spondylolysis. Things such as cuts, bruises and breakages of bone, without antiseptics, proper facilities or knowledge of germs, would become very serious if infected.[8] There is also evidence of rickets bone deformity and bone wastage (Osteomalacia),[9] which is caused by a lack of Vitamin D.

The life expectancy in prehistoric times was low, 25–40 years,[10] with men living longer than women; archaeological evidence of women and babies found together suggests that many women would have died in childbirth, perhaps accounting for the lower life expectancy in women than men. Another possible explanation for the shorter life spans of prehistoric women may be malnutrition; men, as hunters, generally received better food than their female counterparts, who would subsequently have been less resistant to disease.[11]

Treatments for disease

Plant materials

Plant materials (herbs and substances derived from natural sources),[12] were among the treatments for diseases in prehistoric cultures. Since plant materials quickly rot under most conditions, historians are unlikely to fully understand which species were used in prehistoric medicine. An idea can be obtained by looking at the climate of the respective society and which species continue to grow there today[13] and through anthropological studies of existing indigenous peoples.[14][15] Unlike the ancient civilisations which could source plant materials internationally, prehistoric societies would have been restricted to localised areas, though nomadic tribes may have had a greater variety of plant materials at their disposal than more stationary societies.

Herbs such as Rosemary may well have been used for medicinal purposes by prehistoric peoples.[16][17][18]

The effects of different plant materials would have been found through trial and error.[19] Dispensal and gathering of plant materials was handled by women, who cared for the health of their family.[20] Plant materials have remained an important cure for diseases throughout history, despite the advancement of other cures and techniques, and are known to be an effective way of treating many ailments at present.[21][22][23] As they would not have been able to record the effects of different herbs, knowledge of them would have been passed down orally through the generations.

There has been suggestion that the Piptoporus betulinus, which are commonly found in alpine environments, could have been used as a basic laxative by prehistoric peoples living in those areas (Northern Europe), since it is known to bring on short bouts of diarrhoea when ingested,[4] and was found among the possessions of a mummified man.

The use of earth and clays

Earths and clays may have provided prehistoric peoples with some of their first medicines. This is related to geophagy, which is extremely widespread among animals in the wild as well as among domesticated animals. In particular, geophagy is widespread among contemporary nonhuman primates.[24] Also, early humans could have learned about the use of various healing clays by observing animal behavior. Such clay is used both internally and externally, such as for treating wounds, and after surgery (see below). Geophagy, and the external use of clay are both still quite widespread among aboriginal peoples around the world, as well as among pre-industrial populations.

Surgery

Trepanning (sometimes trephining) was a basic surgical operation carried out, predominantly by medicine men, in prehistoric societies across the world,[5][25] although evidence shows a concentration of the practice in Peru.[5][21][26] Several theories question the reasoning behind trepanning; it could have been used to cure certain conditions such as headaches and epilepsy,[27][28]. These might have been considered effects of an evil spirit trapped within a person. Despite it being medically inappropriate in the vast majority of cases, and very dangerous procedure to carry out[29] there is evidence of bone tissue surrounding the surgical hole partially grown back, therefore survival of the procedure did occur.[21]

The plate of skull bone, sometimes as large as 5 cm (2 in) in diameter, would have been kept with the person until their death, serving as a charm or in some spiritual or religious capacity; burial of this bone plate was thought to return the body to its full state for the afterlife. Trepanning is amongst few surgical operations to be carried out in prehistoric times; other surgery was rarely undertaken; medicine men had neither the training or the specialised equipment required to do surgery on the internal body. The procedure would have taken around 60 minutes in a single session, and if done in several sessions, it could have taken up to 12 days to complete.

Many prehistoric peoples, where applicable (geographically and technologically), were able to set broken or fractured bones using clay materials. An injured area was covered in clay, which then set hard so that the bone could heal properly without interference.[30] Also, primarily in the Americas, the pincers of certain ant species were used to close up wounds from infection; the ant was held above the wound until it bit, where its head would be removed allowing the pincers to remain and hold close the wound.[31]

Magic and medicine men

Medicine men (also witch-doctors, shamans) maintained the health of their tribe by gathering and distributing herbs, performing minor surgical procedures,[33] providing medical advice and supernatural treatments such as charms, spells and amulets to ward off evil spirits.[34] In Apache society, as would likely have been the case in many others, the medicine men initiate a ceremony over the patient, which is attended by family and friends. It consists of magic formulas, prayers and drumming. The medicine man then, from patients' recalling of their past and possible offenses against their religion or tribal rules, reveals the nature of the disease and how to treat it.

They were believed by the tribe to be able to contact spirits or gods and use their supernatural powers to cure the patient, and, in the process, remove evil spirits. If neither this method nor trepanning worked, the spirit was considered too powerful to be driven out of the person. Medicine men would likely have been central figures in the tribal system, because of the their medical knowledge and because they could seemingly contact the gods. Their religious and medical training were, necessarily, passed down orally.[35]

The problem of evidence

The definition of "prehistoric" dictates that there is no written evidence which can be used for investigation into this period of history. Historians must use other sources such as human remains and anthropological studies of societies living under similar conditions. A variety of problems arise when the aforementioned sources are used.

Human remains from this period are rare and many have undoubtably been destroyed by burial rituals or made useless by damage.[36][37] The most informative archaeological evidence are mummies, remains which have been preserved by either freezing or in peat bogs;[38][39] no evidence exists to suggest that prehistoric people mummified the dead for religious reasons, as Ancient Egyptians did. These bodies can provide scientists with subjects' (at the time of death): weight, illnesses, height, diet, age and bone conditions,[40] which grant vital indications of how developed prehistoric medicine was.

Not technically classed as 'written evidence', prehistoric people left many kinds of paintings, using paints made of minerals such as lime, clay & charcoal and brushes made from feathers, animal fur or twigs, on the walls caves. Although many of these paintings are thought to have a spiritual or religious purpose,[41] there have been some, such as a man with antlers (thought to be a medicine man), which have revealed some part of prehistoric medicine. Many cave paintings of human hands have shown missing fingers (none have been shown without thumbs), which suggests that these were cut off for sacrificial or practical purposes, as is the case among the Pygmies and Khoikhoi.[42]

The writings of certain cultures (such as the Romans) can be used as evidence in discovering how their contemporary prehistoric cultures practiced medicine. People who live a similar nomadic existence today have been used as a source of evidence too, but obviously there are distinct differences in the environments in which nomadic people lived; prehistoric people who once lived in Britain for example, cannot be effectively compared to aboriginal peoples in Australia, because of the geographical differences.[43]
