发热时身体热气蒸腾，大便已经干硬。皮肤红艳如锦缎，这叫做“斑”。不要将这种症状与麻疹的毒邪混为一谈，那些平庸的医生往往不加区分地看待。
发斑的症状特点是血分有余而气分不足；麻疹的证候则是营血亏耗较多。在麻疹初起发热时，皮肤上感觉好像有红斑，但不要当作真正的“斑”来使用寒凉药物。
麻疹初起，整体表现很像伤寒。但如果中指发冷，这才是麻疹的征兆。如果在发热时，大便闭结或已经干硬，皮肤上出现红色如锦缎般的斑块，这是热邪滞留于胃中，属于“发斑症”，而不是麻疹。不能误认为是麻疹，从而妄用发散解表的药剂。如果误用发散药，反而会增加病情的危重程度。适宜使用加味人参白虎汤（参见第二十九条），去掉方中的人参、天花粉、甘草、粳米，加入大青、玄参、生地黄、枳实、木通来主治。这样一方面可以化解斑屑，另一方面也不会妨碍麻疹的正常透发。如果大便不通畅，可以用三黄丸轻微通便。发斑这类病症，是血有余而气不足；麻疹则是火热煎熬血分，导致血液大量虚耗，阳气偏旺，因此出现这种情况。如果在发热时，皮肤上感觉好像有斑屑，这实际上不是斑，而是风寒夹杂热邪在体表形成的瘾疹（风团/荨麻疹类）。这类证候，只适宜使用疏散解表的药剂，内部配合清热解表的药物。等到麻疹完全透发出来，瘾疹自然会消退。千万不要误认为是真正的斑，而施用苦寒的药物，比如使用紫草、红花、石膏等化斑的药物，导致大便水泻不止，元气日益衰弱，致使麻疹内陷而无法救治。可以使用葛根解肌汤（参见第五条），去掉赤芍、甘草，进行治疗。如果麻疹已经发出但夹杂斑症，以犀角红花饮为主治方剂。
朱氏说：中指发冷的是麻疹征兆。发斑症忌讳使用发散药物。瘾疹与发斑的区别，就像上面所说的那样。
The body emits intense heat, and the stool has already become hard. The skin is red like brocade, which is named "Ban" (macules/petechiae). Do not confuse this with the toxin of measles; foolish doctors often view them identically.
In cases of Ban, blood excess and Qi deficiency prevail. In measles patterns, there is significant depletion of Ying and Blood. During the initial fever of measles, if the skin feels as though spots are appearing, do not treat it as true Ban using cold-natured medicines.
At the onset of measles, the presentation closely resembles Taiyang disease (Shanghan). However, if the middle finger is cold, it indicates a measles pattern. If during fever, the stool is constipated or already hard, and the skin appears red like brocade, this indicates heat lingering in the Stomach, constituting a "Ban" syndrome, not measles. It must not be mistaken for measles, nor should dispersing agents be recklessly used. Using dispersing agents will instead exacerbate the severity. The appropriate formula is Jiawei Renshen Baihu Tang (Modified Ginseng and White Tiger Decoction) [see Article 29], removing Renshen (Ginseng), Tianhuafen (Trichosanthes Root), Gancao (Licorice), and Jingmi (Rice), and adding Daqing (Indigo Naturalis), Yuan Shen (Scrophularia Root), Sheng Dihuang (Rehmannia Root), Zhishi (Immature Bitter Orange), and Mutong (Akebia Stem). This serves to resolve the macules without hindering the eruption of measles. If the stool remains unsmoothed, Sanhuang Wan (Three-Yellow Pill) can be used to mildly induce purgation. The Ban syndrome is characterized by blood excess and Qi deficiency. Measles, however, involves fire scorching the blood level, leading to significant blood depletion and hyperactive Yang Qi, resulting in these manifestations. If, during fever, the skin feels as though macules are appearing, this is actually not Ban, but Yin Zhen (urticaria/wind rash) formed by wind-cold combined with heat in the exterior. For such patterns, only dispersing agents combined with internal clearing and resolving herbs should be used. Once the measles fully erupts, the Yin Zhen will naturally recede. Carefully avoid mistaking it for true Ban and administering bitter-cold substances such as Zicao (Arnebia Root), Honghua (Safflower), or Shigao (Gypsum), which would cause incessant watery diarrhea, daily decline of Yuan Qi, and inward collapse of measles, rendering it incurable. Keguan Jieji Tang (Pueraria Decoction to Release the Muscles) [see Article 5], removing Chishao (Red Peony Root) and Gancao (Licorice), may be applied. If measles have erupted but are complicated by Ban, Xijiao Honghua Yin (Rhino Horn and Safflower Decoction) is indicated.
Master Zhu stated: Coldness of the middle finger indicates a measles pattern. Ban is contraindicated for dispersing treatments. The distinction between Yin Zhen and Ban is as described above.
