- Abstract: Yang diseases of the Shanghanlun (shōkanron) list the Three Yangs in the order of early yang stage pattern (taiyōbyō), middle yang stage pattern (yōmeibyō) and late yang stage pattern (shōyōbyō). However, in Japan, the order is early yang stage pattern, late yang stage pattern, and middle yang stage pattern. A survey of Japanese disease history revealed that by the Edo period smallpox, measles, and influenza were infectious, febrile, and highly lethal. Furthermore, these diseases exhibited bimodal fever. We investigated and examined how Kampo doctors viewed the order of the Three Yangs in the Shōkanron from the literature of the Edo period, and found that the epidemic period of these three diseases coincided with the increase in the number of doctors advocating late yang stage pattern. It is thought that the Three Yangs in Japan came to be recognized in the order of early yang stage pattern, late yang stage pattern, and middle yang stage pattern through these three diseases that became prevalent from around 1700.
