头面周身，未至腿足，紫黑色坚浓之痂。惟宜节饮食，慎风寒。
险 气血已竭，未易收靥，停浆不敛，身重发热（补脾利水解毒。）凡曾经泄泻后，所见诸证
皆作虚治（十全大补、异功、木香参酌。）泄泻而烦渴不止，大用升提。浆足难收，大便结实，
略宜疏通。或风冷入胃，下利脓粘，热渗膀胱，小便尿血，并宜清利。痘后发热，午前是阳盛，
宜清热；午后是阴虚，宜滋阴。大热便实，恐变急惊，微热便溏，恐变慢惊。

Shun (Favorable) Pattern: Dietary intake remains normal, Qi mechanism is regulated, blood is harmonious, pathogenic toxins are resolved, and the pustular fluid retracts. The scab color matures and converges, subsequently turning into a yellow wax color, gradually changing to a sauce-brown hue. Scabbing begins at the lips and philtrum, spreading to the head, face, and entire body, but has not yet reached the legs and feet, forming purple-black, hard, and thick scabs. At this stage, one should only regulate diet and carefully guard against wind and cold.
Xian (Dangerous) Pattern: Qi and blood have been exhausted, making it difficult for scabbing to occur; the pustular fluid stagnates and fails to converge, accompanied by heavy sensation in the body and fever (Treatment principle: Tonify Spleen, promote urination, resolve toxins). For any symptoms appearing after previous diarrhea, they should all be treated as deficiency patterns (Reference Shiquan Dabu Decoction, Yigong San, or Muxiang San for consideration). If diarrhea is accompanied by incessant irritability and thirst, strong lifting methods should be employed. If there is sufficient pustular fluid but difficulty in scabbing, with solid stool, slight unblocking is appropriate. If wind-cold enters the Stomach causing dysentery with pus and mucus, or if heat penetrates the Bladder causing hematuria, clear and promote urination methods are suitable. Fever after smallpox/chickenpox occurring before noon indicates Yang excess, requiring clearing heat; fever after noon indicates Yin deficiency, requiring nourishing Yin. High fever with solid stool fears transformation into acute convulsions (Ji Jing Feng); mild fever with loose stool fears transformation into chronic convulsions (Man Jing Feng).
Main Formula: Danggui (Angelicae Sinensis Radix), Shaoyao (Paeoniae Radix Alba, stir-fried with wine), Baizhu (Atractylodis Macrocephalae Rhizoma), Fuling (Poria), Shanyao (Dioscoreae Rhizoma), Yiren (Coicis Semen), Jiegeng (Platycodonis Radix) in equal parts; Gancao (Glycyrrhizae Radix et Rhizoma) in half dose; Lianrou (Nelumbinis Semen) seven pieces. Add Maidong (Ophiopogonis Radix) and Wuweizi (Schisandrae Fructus) for thirst; add Renshen (Ginseng Radix et Rhizoma) for deficiency; add Mutong (Akebiae Caulis) for failure to converge. Decoct in water and take orally.
Ni (Adverse) Pattern: Qi stagnation leads to blood coagulation; toxin retention results in thin pustular fluid. Inability to retract fluid and form scabs leads to dryness and external peeling.
Shun (Favorable) Pattern: Scars open and protrude, showing a peach-red color, with bright luster and refreshing spirit.
Xian (Dangerous) Pattern: Scars are pale red and do not open; tonifying Qi and Blood is indicated. If the color is entirely white, urgent use of major tonification is required, otherwise danger persists for months. From fever to this stage, the body is usually warm (lack of heat indicates Water Retention pattern). If there is high fever with purple, dry, and scorched scars, significant cooling and heat-clearing are necessary. For dense, critical cases, if the patient can eat and external scabs fall off in patches, do not forcibly peel them. Exposure to wind too early transforms into sores/ulcers that recur annually. If weakness follows scabbing, with trembling upon standing, etc., use the following formula.
Main Formula: Renshen (Ginseng Radix et Rhizoma), Baizhu (Atractylodis Macrocephalae Rhizoma), Fuling (Poria), Danggui (Angelicae Sinensis Radix), Chuanxiong (Ligustici Chuanxiong Rhizoma), Baishao (Paeoniae Radix Alba), Shudi (Rehmanniae Radix Preparata), Huangqi (Astragali Radix), Zhimu (Anemarrhenae Rhizoma), Maidong (Ophiopogonis Radix) in equal parts; Gancao (Glycyrrhizae Radix et Rhizoma) in half dose. Decoct in water and take orally. Add Mutong (Akebiae Caulis) for astringent urination; add Rouguou (Myristicae Semen) for diarrhea. Scabs that fail to fall when they should indicate Fire excess; treat with Chailing San adjusted with Chen Sha Liuyi San, and externally apply滑石 (Talcum) powder mixed with honey water.
Ni (Adverse) Pattern: Scabs resemble bamboo husk, accompanied by pus and blood in stool; if chronic convulsions develop, eyes lack spirit and complexion is cyanotic. Or dental gangrene occurs; or carbuncles/toxins arise, discussed in separate sections later.
