论曰凡伤寒热毒内盛，多发 疮者，以病患里实表虚故也，里实则毒瓦斯不能内消。表虚
故乘虚发于肌肉而成疮也，其疮大小形如豌豆，其色或白或赤，若头作瘭浆戴白脓者，其毒
则轻，若紫黑色作根，隐隐在肌肉里者，其毒则重，甚者周匝遍身，五脏七窍皆有也。

论述说：凡是伤寒热毒在体内炽盛，导致多发疮疡的，是因为患者里实表虚的缘故。里实则毒邪之气不能在内消散；表虚则毒邪乘虚侵入肌肉而形成疮疡。这些疮疡大小形状像豌豆，颜色有的白、有的红。如果疮头起脓疱、顶部有白色脓液的，其毒性较轻；如果是紫黑色且根深，隐隐潜伏在肌肉里的，其毒性较重。严重的甚至周身遍布，五脏七窍都有发生。

Commentary states: In cases where the heat-toxin of Cold Damage (Shanghan, a syndrome caused by exogenous cold pathogens) is excessively abundant internally, leading to the frequent occurrence of sores, it is due to the patient having interior excess and exterior deficiency. Interior excess prevents the pathogenic factors from being resolved internally; exterior deficiency allows the pathogens to invade the muscles through the void, forming sores. These sores are of varying sizes and shaped like peas. Their color may be white or red. If the head of the sore forms a pustule with white pus on top, the toxicity is mild. If the sore is purple-black with deep roots, faintly hidden within the muscles, the toxicity is severe. In extreme cases, they cover the entire body, affecting the five Zang organs (Heart, Liver, Spleen, Lung, Kidney) and seven orifices.
