痘疹痊愈后出现倦怠乏力的症状，这是病情由坏转好、否极泰来的征象，自然应当调养气血，以恢复人体的真元之气。然而，也有患者原本神气就虚弱，并且兼受客热邪气的困扰，导致精神不能舒畅，这种情况不能单纯当作虚证来治疗，适宜以清热为主，兼用补气的方法。如果只使用保元汤（一种补益元气的基础方剂），那么邪气得到补益反而会更加旺盛。
人的身体，必须元气坚固，精血才能凝聚，视物行为才有常态。眼睛白睛外露的症状，多发生在痘痂脱落之后，这是因为元气亏损，营血耗伤，不能滋润濡养眼部脉络，导致督脉拘挛紧急，致使眼球向上吊起，所以会出现这种症状，这并不是世俗所说的“风候”（惊风之类）。如果出现意识丧失、不省人事的情况，属于不治之症。如果只是眼睛白睛外露而没有其他症状的，可以使用十全大补汤（具有温补气血功效的方剂）作为主方治疗。只有在痘疹发出七天内出现眼睛白睛外露的，说明毒邪尚未解除，真元已经离散，这肯定是难以治疗的。
有一类情况是：痘疮收靥后，痂皮浓厚且脱落迟缓，与肌肉分离但不粘连的，属于吉兆。有一类情况是：痂皮脱落后，瘢痕颜色红润且没有凹凸不平，饮食和二便都正常的，属于吉兆。有一类情况是：凡是自行吞食痘痂的人，即使有其他症状也不会死亡。
有一类情况是：痘疹已经结痂但没有焦枯脱落的，这是余毒为害，或者是过食辛辣热性的药物，导致胃热熏蒸肌表。或者是全身痂皮都已脱落，只有头面部没有焦枯脱落的，这是毒邪聚集在头部阳经交会之处。这两种情况都适宜服用大连翘饮（具有清热解毒功效的方剂）并加减化裁。有一类情况是：痘痂到二十天或一个月仍然粘连肌肉不脱落，或者发痒的，这是因为发汗解表太过，导致气虚无力温煦，血虚无力濡养，治疗适宜用人参、当归、地黄之类的药材，调养气血，再佐以荆芥来通达肌表，疏散腠理中郁伏的火邪。有一类情况是：因为发痒，以致抓破剥去痂皮，又重新灌浆如同疮疥一样的，这是血热而气虚的表现，适宜用人参补益卫气，并加入牡丹皮、地骨皮、地黄、连翘等凉血养营的药物。有一类情况是：痂皮不脱落反而昏迷沉睡、不省人事的，这是脾胃极度虚弱的表现，适宜用人参清神汤（具有益气醒神功效的方剂）作为主方治疗。有一类情况是：痘疹收靥后瘢痕呈红紫色的，这是血热毒盛的表现，应当以凉血解毒为主进行治疗。有一类情况是：痘疹结痂后嘴唇干裂不能覆盖牙齿的，急需给予败毒凉血的药物，否则一定会转变为走马牙疳（一种严重的口腔坏死性疾病）而死；如果是由于血气枯竭，不能润养督脉和任脉导致喘急的，应当从补养方面入手治疗。有一类情况是：痘疹后出现口角紧闭僵硬、腹痛直达肚脐、冷汗如雨下，疼痛停止时出汗也停止且脉搏弦紧的，这是因为瘢痕部位受到风寒侵袭所致，适宜采用散风养血的治疗方法，如使用秦艽、钩藤、当归、防风、生姜、肉桂、木香之类的药材。
After the resolution of smallpox, fatigue and lassitude are signs of a transition from adversity to prosperity (from "Pi" to "Tai"). It is appropriate to nourish Qi and Blood to restore the True Yuan (Original Energy). However, some patients have inherently weak Shen (Spirit) and Qi, complicated by confinement from exogenous heat pathogens, resulting in an inability of the spirit to flow freely. This condition should not be treated solely as deficiency; the primary approach should be clearing heat while simultaneously tonifying Qi. If only Baoyuan Tang (Preserve Origin Decoction) is used, the pathogenic factors will be strengthened by the tonification and become more vigorous.
In the human body, when Original Qi is solid, Essence and Blood can coalesce, and vision and movement remain regular. The symptom of white sclera being exposed often occurs after the scabs fall off. This is due to the depletion of Original Qi and consumption of Ying (Nutritive) Blood, which fail to moisten and nourish the meridians, leading to spasms and tension in the Du Meridian (Governing Vessel), causing the eyes to roll upward. Thus, this symptom arises; it is not what the laypeople call "Wind Syndrome" (convulsions or tetany-like symptoms). If there is loss of will, consciousness, and awareness of one's surroundings, it is incurable. If there is only exposed white sclera without other symptoms, Shiquan Dabu Tang (Comprehensive Great Tonifying Decoction) can be used as the principal formula. However, if the eyes expose white sclera within seven days of eruption, the toxin has not yet resolved, and the True Yuan has already dispersed; such cases are undoubtedly difficult to treat.
One type of case: After the smallpox pustules dry up, the scabs are thick and fall off late, separating from the flesh but not adhering; this is auspicious. One type of case: After the scabs fall off, the scars are red and lustrous without depression or elevation, and diet and bowel/bladder functions are normal; this is auspicious. One type of case: Those who voluntarily eat their own smallpox scabs will not die even if they present with other symptoms.
One type of case: Smallpox has formed scabs but has not become necrotic and fallen off; this indicates harm from residual toxins, or excessive consumption of pungent and hot medicines, causing Stomach Heat to affect the muscle surface. Or, if the entire body sheds scabs except for the head and face which do not necrose and fall off; this indicates toxin accumulation at the Yang Hui (Meeting of Yang vessels on the head). Both situations are suitable for treating with modified Dalianqiao Yin (Great Detoxifying Lonicera Decoction). One type of case: Scabs adhere to the flesh and do not detach after twenty days or a month, or cause itching; this is due to excessive sweating/releasing of the exterior, leading to Qi deficiency lacking the power to warm, and Blood deficiency lacking the power to moisten. Treatment should involve herbs like Renshen (Ginseng Radix et Rhizoma), Danggui (Angelicae Sinensis Radix), and Dihuang (Rehmanniae Radix) to nourish Qi and Blood, assisted by Jingjie (Schizonepetae Herba) to reach the muscle layer and disperse latent fire in the interstices. One type of case: Itching leads to peeling off the scabs, and pus fills again resembling sores or impetigo; this is due to Heat in the Blood and deficiency of Qi. Treatment should use Renshen to tonify Wei (Defensive) Qi, adding Mudanpi (Moutan Cortex), Digupi (Cortici Lycii Radicis), Dihuang, and Lianqiao (Forsythiae Fructus) to cool the Ying level. One type of case: Scabs do not fall off, but instead there is coma, deep sleep, and unconsciousness; this indicates severe deficiency of the Spleen and Stomach. Ren Shen Qingshen Tang (Ginseng Spirit-Clearing Decoction) should be used as the principal formula. One type of case: After the rash resolves, scars are red and purple; this indicates excess Heat in the Blood and virulent toxins. Treatment should focus primarily on cooling the Blood and resolving toxins. One type of case: After smallpox scabbing, the lips are cracked and cannot cover the teeth; urgent administration of detoxifying and blood-cooling remedies is required, otherwise it will inevitably transform into Zouma Yagan (Running Horse Gum Necrosis) leading to death. Alternatively, if it is due to exhaustion of Qi and Blood failing to nourish the Du and Ren (Conception) meridians, causing panting and urgency, treatment should proceed from tonification and nourishment. One type of case: After smallpox, there is lockjaw and stiffness, abdominal pain extending to the umbilicus, cold sweat pouring like rain. When the pain stops, the sweating also stops, and the pulse is wiry and tight; this is due to Wind-Cold invading the scarred areas. Treatment should scatter Wind and nourish Blood, using herbs such as Qinjiao (Gentianae Macrophyllae Radix), Gouteng (Uncariae Ramulus cum Uncis), Danggui, Fangfeng (Saposhnikoviae Radix), Shengjiang (Zingiberis Rhizoma Recens), Rougui (Cinnamomi Cortex), and Muxiang (Aucklandiae Radix).
