Today is the day you learn about the history of medicine.
Unwritten history is not easy to interpret, and, although much may be learned from a study of the drawings, bony remains, and surgical tools of early humans, it is difficult to reconstruct their mental attitude toward the problems of disease and death. It seems probable that, as soon as they reached the stage of reasoning, they discovered by the process of trial and error which plants might be used as foods, which of them were poisonous, and which of them had some medicinal value. Folk medicine or domestic medicine, consisting largely in the use of vegetable products, or herbs, originated in this fashion and still persists.
But that is not the whole story. Humans did not at first regard death and disease as natural phenomena. Common maladies, such as colds or constipation, were accepted as part of existence and dealt with by means of such herbal remedies as were available. Serious and disabling diseases, however, were placed in a very different category. These were of supernatural origin. They might be the result of a spell cast upon the victim by some enemy, visitation by a malevolent demon, or the work of an offended god who had either projected some object—a dart, a stone, a worm—into the body of the victim or had abstracted something, usually the soul of the patient. The treatment then applied was to lure the errant soul back to its proper habitat within the body or to extract the evil intruder, be it dart or demon, by counterspells, incantations, potions, suction, or other means.
One curious method of providing the disease with means of escape from the body was by making a hole, 2.5 to 5 cm across, in the skull of the victim—the practice of trepanning, or trephining. Trepanned skulls of prehistoric date have been found in Britain, France, and other parts of Europe and in Peru. Many of them show evidence of healing and, presumably, of the patient’s survival. The practice still exists among some tribal people in parts of Algeria, in Melanesia, and perhaps elsewhere, though it is fast becoming extinct.
Magic and religion played a large part in the medicine of prehistoric or early human society. Administration of a vegetable drug or remedy by mouth was accompanied by incantations, dancing, grimaces, and all the tricks of the magician. Therefore, the first doctors, or “medicine men,” were witch doctors or sorcerers. The use of charms and talismans, still prevalent in modern times, is of ancient origin.
And that is how early medicine was.
