Buried Manuscripts and Their Dates
In the twelfth year of Emperor Wen of Han, or 168 BCE, a group of bamboo-slip and silk manuscripts was sealed in tomb 3 at Mawangdui, Changsha, with its occupant. A dated wooden document from the tomb provides a dependable chronological marker: these copies existed by the time of burial. The initial formation of knowledge, its organization into text, the production of a particular copy, and its deposition in a tomb were separate stages, not one act of creation in 168 BCE.
After tomb 3 was excavated in 1973, editors gradually identified writings about diseases, the body, remedies, and nourishing life among damaged and adhering slips and silk. Familiar titles such as Wushier Bingfang, Zubi Shiyi Mai Jiujing, and Daoyin Tu were largely assigned by modern editors. Calling them collectively the “Mawangdui medical manuscripts” is useful for research, but in antiquity they were not a single medical compendium with unified chapter order, authorship, and theory.
Vessels and Descriptions of the Body
Zubi Shiyi Mai Jiujing and Yinyang Shiyi Mai Jiujing describe the body through routes that can be followed from one location to another. Starting at places such as the feet or arms, readers trace a vessel’s course along muscles, joints, and the torso, then read the symptoms associated with it. Yin and yang names for the limbs relate to inner and outer bodily positions, allowing widely separated pains and abnormalities to be grouped under one entry.
The two texts agree in some routes, names, and symptoms and differ in others, revealing bodily knowledge still undergoing organization. They list eleven vessels, unlike the later twelve-channel system. Nor are the vessels consistently described as an interconnected circulating network, and their relations with internal organs are not yet fully systematized. Moxibustion has a place in them, but they lack the later integrated system of named points and acupuncture techniques. Comparing these differences shows which concepts later classics brought together, rather than forcing every ancient statement into a mature channel diagram.
Disease Names and Remedy Entries
Wushier Bingfang organizes techniques by disease names or bodily problems, often giving more than one approach under a heading. Entries for wounds caused by metal weapons and other injuries, for example, separately describe stopping bleeding, relieving pain, or treating persistent wounds. They list plants, animal materials, fats, and ointments, and use verbs such as boil, grind, apply, and drink to describe preparation and administration. Some also record prohibitions or conclude with expressions such as “tried.” Materials, procedures, and experience of use are thereby compressed into units of knowledge that could be copied and consulted.
Another group of entries, written with characters such as you and usually interpreted as referring to warts, combines material treatments with ritual elements including clods of earth, incantations, particular dates, and the Steps of Yu. The compilers preserved these alongside remedies, showing that contemporary healing knowledge accommodated differing understandings of illness. Ancient disease names do not necessarily correspond one-to-one with modern diagnoses, and evaluations such as “tried” are not equivalent to modern clinical validation.
Daoyin and Nourishing Life
The Daoyin Tu uses painted human figures to depict bending, stretching, leaning forward and backward, raising the arms, and other postures. Reconstruction makes forty-four figures identifiable, some with inscriptions alongside them. Certain names evoke animals; others refer to body parts or discomforts being addressed. Compared with continuous prose, images more readily preserve the broad relationships of limbs, but cannot alone specify complete sequences, breathing rhythms, or intensity. Entire exercise routines devised from the pictures today therefore also involve modern reconstruction.
The diagram shares one piece of silk with Quegu Shiqi and a version of an eleven-vessel text. This physical proximity matters: knowledge of breathing, diet, bodily movement, and vessels could meet within one reading object. Other writings on nourishing life address daily routines and bodily maintenance. Treatment of illness and everyday self-cultivation overlap in these texts, while image and writing offer different aids to memory, allowing bodily experience to extend beyond a single face-to-face demonstration.
How Medical Knowledge Was Transmitted
Knowledge on bamboo and silk circulated through selection, copying, and teaching. Different copies of the same vessel text and the grouping of several writings on a single silk sheet suggest editorial arrangement and combination. Short remedy entries could readily be supplemented or reused, bodily routes rewritten, and images employed as prompts during demonstration. The texts do not identify every reader, and the presence of medical books in the tomb does not establish that its occupant practiced medicine professionally. The collection itself nevertheless shows that this knowledge was valued.
Comparison with the Maishu from Zhangjiashan and later works such as the Huangdi Neijing reveals shared phrases and concepts alongside changes in vessel counts, routes, and treatments. These manuscripts are not early copies of an unchanging canon, but evidence of the gradual gathering of different forms of knowledge. Damaged characters, interpretations of material names, and chronological relationships among copies still require textual study. Excavated writings are valuable precisely because they restore techniques and understandings of the body outside the received classics to the history of medicine.
