Medical systems in Greece, India and China that explained illness by natural causes and wrote down treatments.
See it on the Technology & Medicine map →How it works
Between about 500 BC and AD 200, three great traditions took shape. Greek doctors, following Hippocrates and later Galen, saw health as a balance of four humors, or body fluids. India's Ayurveda balanced three doshas. China's Yellow Emperor's Inner Classic described qi (vital energy), yin and yang, and pulse diagnosis. Each relied on observation, diet, drugs and sometimes surgery, rather than mainly on gods. Though mostly wrong about how the body works, they were taught for nearly 2,000 years.
Why it mattered
They made medicine a learned, written profession based on natural causes, and Greek ideas dominated European and Islamic medicine until the 1800s.
How we know
Surviving texts: the Hippocratic Corpus, Galen's writings, the Charaka and Sushruta Samhitas and the Huangdi Neijing, plus medical manuscripts excavated at Mawangdui, China, buried in 168 BC.
Still unknown or debated
How much the three traditions influenced one another through trade and contact is debated; many similarities may be independent.

Connections (3)
▸Classical medicine (Greece, India, China) included Sushruta and AyurvedaWell documented
The connection
Ayurveda is India's branch of classical medicine. Like Greek humoral medicine, it explains illness as an imbalance of bodily elements, here three doshas, and treats it with diet, drugs and regimen. Its Sushruta Samhita stands out among classical texts for its detailed surgery.
When and how
Northern India, roughly 600 BC to AD 300, with the Charaka and Sushruta Samhitas as core texts.
How we know
The Sanskrit texts survive in manuscripts and were later translated into Arabic, Persian and Tibetan.
Debates and open questions
Similarities between Greek humors and Indian doshas could be independent or reflect contact; scholars disagree.
▸Classical medicine (Greece, India, China) included Chinese medicine and acupunctureWell documented
The connection
Between about 500 BC and AD 200, Greece, India and China each built a medical system explaining illness by natural causes rather than spirits alone. China's version rested on qi, yin–yang and the five phases, diagnosed by pulse and treated with herbs, acupuncture and moxibustion — parallel to Greek humours and Indian doshas, but developed separately.
When and how
Warring States and Han China, about 300–100 BC; codified in the Huangdi Neijing and Zhang Zhongjing's Treatise on Cold Damage (about AD 200).
How we know
Dated Han texts and tomb manuscripts, such as those from Mawangdui (168 BC), show the system taking shape.
Debates and open questions
Whether Chinese, Indian and Greek medicine had any early contact along trade routes, or their similarities are coincidence, is debated.
▸Classical medicine (Greece, India, China) was preserved and extended by Islamic Golden Age science and medicineWell documented
The connection
Physicians writing in Arabic inherited Greek medicine (Hippocrates, Galen) through translation, plus Persian and Indian traditions. They did more than preserve it: they ran hospitals, kept clinical case records, described diseases, built up pharmacology and challenged errors — as when al-Razi doubted Galen and Ibn al-Nafis corrected his heart anatomy.
When and how
Baghdad, Rayy, Cairo, Damascus and Córdoba, about 800–1300.
How we know
Arabic translations of Galen, sometimes the only surviving versions of lost Greek works, and original treatises by al-Razi, Ibn Sina and others.
Debates and open questions
Historians debate how original Islamic medicine was versus faithful transmission, a question colored by older European assumptions that downplayed it.
