East Asian medical history was made through adaptation, conflict and movement—not one unbroken tradition.

Present-day borders do not map neatly onto earlier medical worlds. Chinese-language books, Buddhist institutions, envoys, migrants, merchants, drugs, and technologies moved among courts and communities, but movement did not produce uniformity. Healers selected, annotated, translated, rejected, and combined knowledge according to local materials and needs. Korean and Japanese medicine were not provincial copies of a finished Chinese system, and “Chinese medicine” itself changed across regions, dynasties, occupations, and political regimes (Cook, 2023; Suh, 2017).

Terms require the same care. Bencao is used here for the Chinese genre concerned with medicinal substances and natural knowledge, often translated as “materia medica.” Rangaku, or “Dutch learning,” names Japanese study through Dutch-language books and contacts during the Tokugawa period; it was neither all European knowledge nor a wholesale rejection of Chinese-style medicine. “Traditional Chinese Medicine,” Japanese Kampo, and Korean medicine are modern institutional categories as well as claims about inheritance. They should not be projected unchanged into the ancient or early modern past (Lei, 2014; Suh, 2017).

This page discusses historical remedies as evidence of past knowledge and practice, not as present-day treatment advice. A recipe's survival in a respected text does not establish modern safety or efficacy: species identification, preparation, dose, toxicity, manufacturing, clinical comparison, and regulation are separate questions. The history of artemisinin is important precisely because researchers transformed a textual clue through repeated extraction, animal studies, chemistry, and clinical investigation.

Second century BCE–tenth century CE: many practices, later canons

Excavated texts complicate any search for a single origin of Chinese medicine. Manuscripts from tombs and frontier sites preserve drug recipes, cauterisation, exercises, dietary regimens, talismans, incantations, and explanations involving spirits or patterned movement of qi. These practices did not pass through a simple sequence from “magic” to “science.” The received Huangdi neijing (Inner Classic of the Yellow Emperor) is therefore better understood as a composite textual tradition shaped by later editing than as the work of the legendary Yellow Emperor or a transcript of one ancient medical system (Cook, 2023).

Chinese-language writings nevertheless became important resources beyond successive Chinese states. The Ishinpō, compiled in Japan in 984 by the court physician Tamba Yasuyori, drew on numerous earlier Chinese medical books. The oldest complete surviving copy is itself a layered object: most scrolls date from the twelfth century, with later replacements and annotations. It shows selection and preservation at a Japanese court, not the everyday practice of everyone in Heian Japan (National Institutes for Cultural Heritage, Japan).

Eleventh–eighteenth centuries: states, print and local reworking

Government compilation mattered, but court sponsorship never monopolised therapeutics. State-commissioned bencao works, private publishing, travelling drug merchants, urban pharmacies, household manuals, and literati investigation created overlapping routes for knowledge. He Bian's history of early modern pharmacy rejects the older picture of a static tradition: commercial exchange and changing book culture generated new arguments about substances and classification even as compilers cited ancient authority (Bian, 2020).

Li Shizhen's Bencao gangmu (Compendium of Materia Medica), first published in 1596, reorganised and criticised a large inherited literature rather than merely listing timeless herbal cures. Copies reached Japan by 1604; Japanese editions and corrections followed, while works such as Kaibara Ekiken's Yamato honzō (1709) challenged parts of Li's scheme and recast natural knowledge around locally observed plants and animals. Print enabled both authority and disagreement (National Diet Library, “Natural History during the Edo Period”).

In Joseon Korea, King Seonjo ordered the compilation that became the Donguibogam. Completed under the royal physician Heo Jun and printed by the state in 1613, it assembled earlier Chinese and Korean writings within a Korean court project. UNESCO's Memory of the World record correctly identifies collective support from medical experts and literati, which cautions against treating the book as one man's unaided achievement. The record is also a heritage nomination submitted by the Republic of Korea: it establishes the registered edition and its institutional history, not the efficacy of every remedy or an uncontested claim to medical priority (UNESCO).

European anatomy entered this already plural book world through restricted but consequential contacts. The 1774 Kaitai shinsho (New Book of Anatomy) was a Japanese translation of a Dutch edition of Johann Adam Kulmus's German anatomical tables. Sugita Genpaku, Maeno Ryōtaku, Nakagawa Jun'an, Katsuragawa Hoshū, and illustrator Odano Naotake worked through several layers of language and image. Its significance lies in collaborative translation and the making of technical vocabulary, not in a single moment when “Western medicine” replaced all earlier knowledge (National Diet Library).

1868–1910: professional medicine, translation and empire

After the Meiji Restoration of 1868, Japan's government built medical schools and credentials through international recruitment and travel. German-speaking medicine acquired particular authority: about 1,200 Japanese medical students studied in German universities between 1868 and 1914, while German physicians taught in Japan. These encounters changed both visiting teachers and Japanese students and helped make German a working language of elite medical science; they were not a passive transfer of a complete European model (Kim, 2014).

The new institutions were also imperial. In Japanese-ruled Taiwan (1895–1945), sanitation, medical training, disease surveillance, and research were tied to occupation and the claim that colonial rule brought “medicine” and “civilisation.” Some programmes produced infrastructure and epidemiological knowledge, but those outcomes do not cancel coercion, racial hierarchy, or the use of health administration to secure the colony. Similar questions attend Japanese rule in Korea from 1910 to 1945, where licensing and institutional categories altered who could claim medical authority (Liu, 2009; Suh, 2017).

In treaty-port China, public health vocabulary itself registered these power relations. Ruth Rogaski traces how weisheng shifted from “guarding life,” associated with personal regimens, toward hygiene, sanitation, laboratory knowledge, and national fitness. The newer usage travelled partly through the Japanese term eisei and returned under conditions of foreign occupation and Chinese state-building. Translation was therefore material and political: it reordered streets, bodies, institutions, and claims to sovereignty (Rogaski, 2004).

1910–1945: epidemic government and medical violence

The pneumonic plague epidemic of 1910–11 spread along the rail and fur-trade routes of northeast China and killed as many as 60,000 people. The Qing government appointed the Penang-born, Cambridge-trained physician Wu Lien-teh to direct Chinese anti-plague work. Masks, isolation hospitals, railway controls, disinfection, police searches, and cremation helped contain disease, but they also subjected migrant workers and urban residents to intrusive state power. Chinese, Japanese, and Russian authorities competed for scientific credibility and territorial influence in a region each sought to control (Summers, 2012).

Delegates from eleven countries met at the International Plague Conference in Mukden (now Shenyang) in April 1911, with Wu as chair. Its 1912 English-language report records bacteriological arguments and official control measures and is valuable as a contemporary institutional source. Because it was produced to formalise expert proceedings, it preserves officials' and delegates' voices far more fully than the experiences of bereaved families, labourers, or people confined by quarantine (Report of the International Plague Conference, 1912).

Claims that scientific medicine advanced inevitably toward humane care collapse in the history of the Imperial Japanese Army's Unit 731. Based near Harbin from 1936 to 1945, the unit used prisoners in lethal experiments and developed biological weapons for use in China. Medical and military researchers made coercion part of organised investigation; describing the work as scientifically crude can inadvertently obscure how professional expertise enabled it. After the war, United States investigators traded immunity from prosecution for access to data, while the 1949 Soviet Khabarovsk trials supplied important but politically situated testimony. The evidential record is therefore fragmented, but the programme's human experimentation and biological warfare are not seriously in doubt (Johnson, 2022).

1945–1989: reconstruction, access, pollution and pharmaceutical research

War's end, the Chinese civil war, the division of Korea, decolonisation, and Cold War alliances produced different health systems rather than one regional model. In the People's Republic of China, twentieth-century “Chinese medicine” was transformed alongside biomedicine and the state, not simply rescued intact from antiquity. The barefoot-doctor programme, operating approximately from 1968 to 1983, extended basic care through briefly trained rural workers. Village-level research shows both valued local service and the programme's role in carrying pharmaceuticals and biomedical practice into the countryside, complicating later celebrations of a seamless synthesis (Lei, 2014; Fang, 2012).

Insurance expansion followed different political paths. Japan achieved universal medical-insurance enrolment in 1961 through multiple employment and national schemes. In the Republic of Korea, compulsory social insurance began with employees of large firms in 1977 and expanded to universal population coverage in 1989. Coverage was not identical to equal access: financing arrangements, private provision, geography, employment, and the range of reimbursed services continued to shape care (Japan Ministry of Health and Welfare; WHO Asia Pacific Observatory).

Postwar industrial growth also produced disease that institutions were slow to acknowledge. Minamata disease was officially reported in Kumamoto Prefecture in 1956; Kumamoto University researchers connected the neurological illness to contaminated seafood, but the Japanese government did not announce its conclusion that factory-released methylmercury caused the disease until 1968. Patients and families then fought over corporate responsibility, compensation, and restrictive certification. The long delay makes Minamata a history of environmental exposure and diagnostic evidence, but also of whose testimony the state accepted (National Institute for Minamata Disease).

Project 523 began in China in 1967 as a secret, military-backed response to drug-resistant malaria during the Vietnam War. Tu Youyou's group searched earlier literature and recipes, then altered extraction methods for qinghao (Artemisia annua); in October 1971 its low-temperature neutral extract produced complete parasite inhibition in a mouse model. Other groups in Yunnan and Shandong isolated crystals, teams in Shanghai and Beijing established chemical structure, and clinicians tested the compound. Secrecy and collective authorship made later allocation of credit difficult. Evidence supports Tu's decisive role, but “Tu discovered an ancient cure” is still misleading: artemisinin emerged from a nationwide network that converted a textual lead into a standardised drug (Miller and Su, 2011; Tu, 2011).

Medical texts survive because courts, families, printers, collectors, and libraries preserved them. They reveal learned categories and selected recipes more readily than treatment outcomes, oral knowledge, or the decisions of patients who never entered an archive. Hospital, colonial, military, and public-health records are differently uneven: they may count cases precisely while rendering patients as populations to be inspected, isolated, certified, or experimented upon.

Care depended on work that celebrated biographies often hide. Translators made technical vocabularies; illustrators and block-cutters made books usable; merchants identified and moved drugs; midwives and household caregivers managed illness outside formal institutions; nurses, technicians, sanitation workers, and village practitioners implemented programmes credited to senior physicians or states. Class, gender, ethnicity, colonial status, residence, and employment affected who could obtain credentials, enter an insured scheme, refuse an intervention, or make harm publicly legible.

The references below therefore perform different tasks. Academic histories supply interpretation and expose disputes; museum and library catalogues establish the material history of surviving books; official health-system accounts provide policy dates; the 1912 plague proceedings and Tu Youyou's retrospective article record expert actors' own claims. No single source speaks for “East Asia,” and this selected chronology remains thinner for household care, Indigenous and minority communities, Mongolia, North Korea, rural Korea and Japan, childbirth, disability, psychiatry, and patient experience than for state institutions and printed texts.
