Bian Que (扁鵲), also Qin Yueren (秦越人)

論曰余每覽越人入虢之診望齊侯之色未嘗不慨然歎其才秀也

Here is what I have to say. Whenever I read how Yueren made his diagnosis on arriving in Guo, or how he read the face of the Lord of Qi, I never fail to sigh with deep feeling at his brilliant talent.

上古有神農黄帝岐伯伯髙雷公少俞少師仲文中世有長桑扁鵲漢有公乘陽慶及倉公下此以往未之聞也

In ancient times there were Shennong, the Yellow Emperor, Qibo, Bogao, Leigong, Shaoyu, Shaoshi, and Zhongwen. In the ages after them came Changsang and Bian Que, and in the Han dynasty, Gongsheng Yang Qing and Master Cang. Since then, I have heard of no one like them.

一病愈之後。雖經廿日。不得輙喫鮮魚完生菜菓。并飲水及洗浴。房室強行。步當風雨。若有過犯。霍亂必發。更亦下痢。所謂勞發。〈更動之病名曰勞發。〉兪附扁鵲。豈得禁斷。

After the illness has healed, even when twenty days have passed, the sick must not be quick to eat fresh fish or meat, or raw vegetables or fruit. They must not drink water or bathe, insist on sex, or walk out in wind and rain. Anyone who breaks these rules will surely fall ill with sudden vomiting and diarrhea, and the diarrhea will come back as well. This is what is called rōhatsu, a relapse brought on by strain. (An illness that stirs up again is called rōhatsu.) Then not even Yu Fu or Bian Que could stop it.
