【溃烂】痘疮脓液成熟后溃烂，是常见的现象；如果尚未化脓就先溃烂，这称为“烂”。造成“烂”的原因，一是病邪应当发散却未能发散，导致毒气闭塞，出现气喘急促、胸闷烦乱；二是不应当发散却误用发散之法，致使热毒随着阳气突然外泄，全身皮肉溃烂，这是不当使用解表法的过错。治疗宜调理脾胃、增进食欲，使大便通畅，安养营卫之气，促进肌肉生长并解除毒素，解毒时不致过于寒凉，调养时不致过于温热，这才是良法。宜用十全大补汤（用于汗证），去掉桂枝，加入防风、荆芥穗，多服用效果佳。若大便秘结，用胆导法（用于便秘）润肠通便。若脓水不干，用败草散（用于溃烂）敷衬患处。若溃烂处化脓疼痛严重，用天水散（即六一散，见初热章节）配合百花膏（用于收靥期）涂抹。又有因发表过度，外部表现为溃烂而内部虚弱，阳气不能固守，脏腑功能失调导致自发性腹泻，这种情况又急需救里兼解表，由陈氏木香散（用于泻利）主治。出现四肢厥冷的，用异攻散（用于出疹不畅）。
【板黄】【袁】痘疮浆液澄清则毒气尽去，病情痊愈，哪里还会有“板黄”呢？岂不知玉的价值不在于厚薄，而在于质地纯净；珍珠的价值不在于大小，而在于光泽明亮；痘浆的价值不在于饱满，而在于色泽黄亮且灵动。所谓“黄”，是中央土的正色，浆液源于脾，其黄色自然润泽纯正。那些痘疮，气能护卫而不逆乱，血能滋养营气而不受伤，痘囊疏松，脓浆在内部澄清流动，活动而不黏腻堵塞，明润而不呈死色，哪里有所谓的“板黄”呢？如果阴阳背离了正气，枭毒肆意残虐，痘根浅薄劣弱，痘囊塌陷平夷，脓浆在内部澄清流动时变得板滞黏腻，坚硬则死塞而不活动，干燥如蜡且不显明黄，用手指按压，凝结固定不动，这是五脏热盛而阴阳二气隔绝，这就叫做“板黄”。如果仅天庭部位板黄，其余部位润泽灵动，痈毒必结聚于脑项。腮脸板黄，而四肢润泽美好，痘痈必发于肩部。肚腹板黄者，痈起于曲池穴、足三里穴。背脊板黄者，痈结于两侧骶骨。遍身板黄者死。颈项前后板黄者死。头面板黄者死。眼眶及嘴唇上方板黄者死。两胁部、阴囊板黄者死。观察这些情况可知，痘囊中的脓液固然希望其充盈发黄，但更应注重润泽灵动。

[Ulceration] When smallpox pustules mature and ulcerate, it is a common occurrence. However, if they ulcerate before pus has formed, this is termed "Lan" (Ulceration). The causes of "Lan" are: first, when the pathogen should be dispersed but fails to be, leading to blockage of toxic qi, resulting in panting, shortness of breath, chest oppression, and restlessness; second, when dispersion is mistakenly employed despite being contraindicated, causing heat toxins to burst out suddenly with the yang qi, leading to widespread ulceration of skin and flesh. This is the fault of improper use of exterior-releasing methods. Treatment should focus on regulating the spleen and stomach, promoting appetite, ensuring proper bowel movements, nourishing Ying (Nutritive) and Wei (Defensive) qi, promoting muscle regeneration, and detoxifying. Detoxification should not be overly cold, and nourishment should not be overly hot; this constitutes a good method. It is advisable to use Shiquan Dabu Tang (Ten Complete Tonifying Decoction), removing Guizhi (Cinnamon Twig), adding Fangfeng (Saposhnikovia Root) and Jingjie Sui (Schizonepeta Spike), taken frequently for better results. If constipation occurs, use Dan Dao Fa (Gallbladder Suppository Method) to moisten the intestines. If pus fluid does not dry up, apply Baicao San (Decayed Grass Powder) as a dressing. If ulceration with pus formation causes severe pain, apply Tianshui San (Heavenly Water Powder, i.e., Liuyi San) mixed with Baihua Gao (Hundred Flowers Ointment) topically. In cases where exterior-releasing was excessive, leading to external ulceration and internal deficiency, with yang qi failing to hold fast and spontaneous diarrhea due to visceral dysfunction, urgent treatment should rescue the interior while releasing the exterior, primarily using Chen's Muxiang San (Aucklandia Powder). For cold limbs, Yigong San (Yi Gong Powder) is indicated.
[Banhuang / Rigid Yellow][Yuan] When smallpox pus clarifies, toxins are exhausted and health is restored; how could there be "Banhuang"? One must understand that the value of jade lies not in its thickness but in its purity; the value of a pearl lies not in its size but in its luster; the quality of smallpox pus lies not in its fullness but in its yellow color and vitality. "Yellow" is the correct color of Central Earth, and since pus is drawn from the Spleen, its yellow hue naturally appears moist and upright. In healthy cases, Qi protects without rebellion, Blood nourishes Ying without injury, the pustule sac is loose, and the clarified pus flows within, active without stickiness or blockage, bright and moist without a lifeless appearance. Where would such a thing as "Banhuang" exist? If Yin and Yang deviate from righteous qi, and fierce toxins act cruelly, the pustule root is shallow and inferior, the sac collapses flat, and the clarified pus becomes rigid and sticky, hardening into a dead blockage without activity, drying like wax without bright yellow luster. Upon finger pressure, it remains congealed and fixed. This indicates excessive heat in the Five Zang organs and severance of Yin and Yang Qi, which is called "Banhuang." If only the forehead shows Banhuang while the rest is moist and vital, abscesses will surely form at the brain and nape. If the cheeks and face show Banhuang while the four limbs are moist and beautiful, smallpox abscesses will erupt on the shoulders. If the abdomen shows Banhuang, abscesses arise at Quchi (LI11) and Zusanli (ST36). If the back shows Banhuang, abscesses knot at the lateral sacral bones. Generalized Banhuang leads to death. Banhuang at the front and back of the neck leads to death. Banhuang on the head leads to death. Banhuang around the eye sockets and above the lips leads to death. Banhuang on the flanks and scrotum leads to death. Observing these signs, one sees that while smallpox pus should indeed be full and yellow, it is even more crucial that it be moist and vital.
Chengquan San treats Banhuang in smallpox.
