二、飲食不節亦能作病。如薑桂辛物增火，蔗蜜甘冷增水，梨增風，膏膩增地，胡瓜為熱病而作因緣；即是噉不安之食。食者須別其性。若食食已，入腹鎖化，麁者為糞尿，細者融鎖，從腰三孔溜入四支，清變為血，潤澤一身，如塵得水。若身血不充，枯癖焦減。濁者變為脂膏，故諸根減而成垢，新諸根凝而成肉。

Second, lack of moderation in food and drink can also cause illness. For instance, pungent things like ginger and cinnamon increase fire; sweet and cold things like sugar cane and honey increase water; pears increase wind; rich and oily foods increase earth; and cucumbers serve as conditions for hot illnesses; this is eating unsuitable food. One who eats must distinguish their natures. Once food is eaten and enters the stomach, it dissolves and transforms; the coarse becomes feces and urine, and the refined melts and dissolves, trickling from the three orifices of the waist into the four limbs; the clear transforms into blood, moistening the whole body like dust receiving water. If the body's blood is insufficient, it withers, knots, scorches, and diminishes. The turbid transforms into fat and grease; hence the old faculties diminish and become waste, while new faculties congeal and become flesh.
