Prehistoric medicine incorporated plants (herbalism), animal parts and minerals. In many cases these materials were used ritually as magical substances by priests, shamans, or medicine men. It is clear that prehistoric societies believed in both natural and supernatural means of variably causing and treating disease. Plant materials (herbs and substances derived from natural sources), were among the treatments for diseases in prehistoric cultures.
Egypt
The Egyptian Imhotep (2667 - 2648 BC) is the first physician in history known by name. The earliest known surgery in Egypt was performed in Egypt around 2750 BC. The Kahun Gynaecological Papyrus treats women's complaints, including problems with conception. Thirty four cases detailing diagnosis and treatment survive, some of them fragmentarily. Dating to 1800 BC, it is the oldest surviving medical text of any kind. Medical institutions, referred to as Houses of Life are known to have been established in ancient Egypt as early as the 1st Dynasty.
Herodotus described the Egyptians as "the healthiest of all men, next to the Libyans", due to the dry climate and the notable public health system that they possessed. According to him, "[t]he practice of medicine is so specialized among them that each physician is a healer of one disease and no more." Although Egyptian medicine, to a good extent, dealt with the supernatural, it eventually developed a practical use in the fields of anatomy, public health, and clinical diagnostics.
Mesopotamia
The oldest Babylonian texts on medicine date back to the Old Babylonian period in the first half of the 2nd millennium BC. The most extensive Babylonian medical text, however, is the Diagnostic Handbook written by the physician Esagil-kin-apli of Borsippa, during the reign of the Babylonian king Adad-apla-iddina (1069- 1046 BC). Along with contemporary ancient Egyptian medicine, the Babylonians introduced the concepts of diagnosis, prognosis, physical examination, and medical prescriptions.
In addition, the Diagnostic Handbook introduced the methods of therapy and etiology and the use of empiricism, logic and rationality in diagnosis, prognosis and therapy. The text contains a list of medical symptoms and often detailed empirical observations along with logical rules used in combining observed symptoms on the body of a patient with its diagnosis and prognosis.
India
The Atharvaveda, a sacred text of Hinduism dating from the Early Iron Age, is the first Indian text dealing with medicine, like the medicine of the Ancient Near East based on concepts of the exorcism of demons and magic. The Atharvaveda also contain prescriptions of herbs for various ailments. The use of herbs to treat ailments would later form a large part of Ayurveda.
In the first millennium BCE, there emerges in post-Vedic India the traditional medicine system known as Ayurveda, meaning the "complete knowledge for long life". Its two most famous texts belong to the schools of Charaka, born c. 600 BCE, and Sushruta, born 600 BCE. The earliest foundations of Ayurveda were built on a synthesis of traditional herbal practices together with a massive addition of theoretical conceptualizations, new nosologies and new therapies dating from about 400 BCE onwards, and coming out of the communities of thinkers who included the Buddha and others.
The Ayurvedic classics mention eight branches of medicine: kāyācikitsā (internal medicine), śalyacikitsā (surgery including anatomy), śālākyacikitsā (eye, ear, nose, and throat diseases), kaumārabhṛtya (pediatrics), bhūtavidyā (spirit medicine), and agada tantra (toxicology), rasāyana (science of rejuvenation), and vājīkaraṇa (aphrodisiacs, mainly for men). Apart from learning these, the student of Āyurveda was expected to know ten arts that were indispensable in the preparation and application of his medicines: distillation, operative skills, cooking, horticulture, metallurgy, sugar manufacture, pharmacy, analysis and separation of minerals, compounding of metals, and preparation of alkalis.
