Chen Deng
Chen Deng became affected by an illness with symptoms such as a feeling of stuffiness in his chest, facial redness, and loss of appetite. The physician Hua Tuo came to treat him, took his pulse and said, "Sir, there are several "sheng" of parasites in your stomach and you're on the verge of developing an ulcer. This is caused by the consumption of raw food." He then prepared two "sheng" of a concoction for Chen Deng and told him to drink one "sheng" first and finish the remainder a while later. Within a span of time needed to have a meal, Chen Deng vomited up three "sheng" or more of wriggling parasites with red heads. Half of their bodies looked like raw fish slices. He was immediately relieved of his discomfort. Hua Tuo told him, "This illness will affect you again after three years. If you have a good physician to attend to you, then you will be fine." Three years later, Chen Deng experienced the same illness again. However, as Hua Tuo was not around at the time to heal him, Chen Deng died of his illness. He was 38 (or 39 by East Asian age reckoning) at the time of his death.
