论述说：《内经》中提到，热病刚刚好转时，如果吃肉就会复发，吃得过多就会遗留病邪，这是需要禁忌的。这是因为伤寒病刚刚痊愈后，脾胃功能仍然虚弱，（饮食不当）都会导致邪热乘虚而入，重新进入经络，再次形成大病，所以称为“劳复”。治疗应当根据具体的证候表现，辨别是在表还是在里，依据相应的法则进行治疗。

Commentary states: The *Neijing* mentions that when a heat disease is just improving, eating meat will cause a relapse, and overeating will leave residual pathogens; these are prohibitions. This is because after a new recovery from cold damage disease (Shanghan), the Spleen and Stomach are still deficient. [Improper diet] allows pathogenic heat to take advantage of the deficiency, re-entering the meridians and collaterals, thus forming a major illness again. Hence it is called "labor relapse" (Laofu). Treatment should follow the specific syndrome manifestations, determining whether the pathogen is in the exterior or interior, and treating according to the appropriate principles.
