ing into actual medical practice. Among the most
important doctors of the School of Ancient Medi-
cine were Goto Konzan (1659–1733), Yoshimasu
Todo (1702–73), and Yamawaki Toyo (1705–62).
Goto Konzan (1659–1733) viewed the cause of
disease from the perspective of vital force. He
believed that when vital force becomes congested or
congealed in the body, disease occurs. He derived
this view from the metaphysical view that just as vital
force infused the universe and maintained balance
and harmony, so did it infuse the body and create
health. Konzan treated the congestion of vital force
with moxa therapy (see below) and herbal medicine.
Yoshimasu Todo (1702–73) placed great impor-
tance on the observation of bodily symptoms in
diagnosing and treating disease. He carried out
empirical research that he believed proved the effi-
cacy of medical treatments prescribed in ancient
Chinese medical texts. Todo viewed all diseases as
caused by a single poison that created different
symptoms depending on its location in the body. He
treated these poison-caused illnesses with herbal and
other medicines.
Yamawaki Toyo (1705–62) represents a bridge
between Chinese and Western medicine as practiced
in Japan. Although he administered Chinese medi-
cine as an imperial court physician, he doubted the
traditional Chinese view of the structure of the
human anatomy. According to this traditional ana-
tomical view, the human body was conceptualized,
without any empirical or visual verification, as en-
compassing five organs and six viscera that inter-
acted with each other and with the meridians, paths
along the body through which vital force flowed. In
turn, the five organs corresponded to traditional
Chinese views of the five elements: heart/fire, lungs/
metal, kidneys/water, liver/wood, and spleen/earth.
The organs themselves were not a site of treatment
in traditional Chinese medicine, that is, disease was
not caused by malfunctioning organs. Rather, this
anatomical view related to the idea that disease was
caused by imbalances in and disruptions to vital
force and the five elements.
Toyo’s doubts about the traditional view of
human anatomy came about in part because of an
anatomical description in one of the Chinese classics
that asserted that the body contains nine organs. To
determine which anatomical view was correct, Toyo
received permission to dissect a human body, which
he did in 1754. In 1759, Toyo presented the results
of his observations in a publication entitled Zoshi
(Anatomical record). Although Toyo’s findings con-
tradicted the traditional view, the five organs and six
viscera theory remained orthodox. The significance
of Toyo’s experimentation was that it set in motion
the idea of performing empirical observations in a
medical setting through dissection and other means,
a methodology that was much more akin to Western
medicine than to Chinese.
Some Forms of Treatment in Chinese Medicine
Chinese medicine is concerned with the patient as a
whole person, not simply as a set of isolated, discrete
organs and body parts. For this reason, practitioners
of Chinese medicine did not think in terms of med-
ical or disease specialization, but rather in terms of
treating the whole patient and to restore health gen-
erally. Diseases were diagnosed through a reading of
symptoms (sho).
Chinese medicine treated diseases and symptoms
in a variety of ways. Medications, prepared from a
wide variety of plants, animal parts, and other nat-
ural materials such as minerals, were one such form
of treatment. They were administered on the basis
of the symptoms presented by the patient and as
observed by the physician. This was the same diag-
nosis system that Manase Dosan had systematized in
the late medieval period (see above). Appropriate
medicine was then administered on the basis of the
results of this diagnosis.
Physicians usually grew medicinal plants and
herbs themselves, and then prepared the plant mate-
rial for ingestion, often by drying the medicine into
powder form. Medications were prepared according
to different formulae used to treat specific diseases
or symptoms. Ingredients were typically mixed to-
gether to derive the desired medical result. Although
there were guides to formulas for various medica-
tions, different doctors often had their own favorite
formulas for treating a particular illness. When trav-
eling, doctors often carried medicines with them in
case they should be needed by those the physician
chanced to meet along the way.
Another common treatment was acupuncture
(hari). In this procedure, used both for treating spe-
cific diseases and as a preventative to health prob-
