毒火煎灼伤阴血，痘体干枯少润泽，当归活血加味尝，治若少缓变莫测。
【注】色者，血之华也。血和则滋润光莹，血耗则干燥枯竭。痘之毒火入于血分，轻则
红，甚则焦紫。治以救血为急，宜当归活血汤主之。

凉血解毒汤（方见结痂落痂证治）
毒火煎熬灼伤阴血，导致痘体干枯、缺乏润泽。此时应使用加味当归活血汤治疗，若治疗稍有迟缓，病情变化将难以预测。
【注】色泽是血液的外在表现。血液调和则滋润光亮，血液耗损则干燥枯竭。痘疹的毒火侵入血分，轻则发红，重则焦紫。治疗应以救血为急务，适宜用当归活血汤为主方。
当归活血汤
当归、川芎、赤芍、生地、红花、紫草、黄芩、黄连、大黄。
水煎服。
【方歌】加味当归活血汤，痘色干枯服用效果最好，四物汤（当归、川芎、白芍、熟地）配合红花和紫草，再加入黄芩、黄连和生大黄。
铺红多因元气虚弱，血液不能归附于痘体，导致毒邪漫延。肌肤全部发红，痘根颜色赤艳，这是气失去统摄作用的表现，痘疹预后大多凶险。气虚者可用九味神功散补益，毒盛者需用凉血解毒汤清热。
【注】在起胀阶段，血液完全归附于痘体，根部下方有红线紧束，这是正常的形态。如果元气虚弱，血液不归附，导致毒气散漫，肌肤之上痘根颜色紫艳，这是气失去统摄之力，多导致无法救治。如果气虚而痘色微赤，以九味神功散为主方；毒盛且根部颜色鲜艳者，以凉血解毒汤为主方。

人参、黄芪（生用）、紫草茸、红花、前胡、牛蒡子（炒后研碎）、甘草（生用）、白芍药（酒炒）、生地黄。

凉血解毒汤（方剂见结痂落痂证治章节）
The toxic fire scalds and damages Yin-blood, causing the pustules to become dry and withered, lacking moisture. In such cases, Jiawei Danggui Huoxue Tang (Modified Angelica Sinensis Blood-Invigorating Decoction) should be used for treatment; if treatment is delayed even slightly, the progression of the disease becomes unpredictable.
[Note] Color is the outward manifestation of blood. When blood is harmonious, the skin appears moist and lustrous; when blood is depleted, it becomes dry and withered. The toxic fire of smallpox enters the blood level: mild cases present with redness, while severe cases present with scorched purple discoloration. Treatment must prioritize saving the blood, and Danggui Huoxue Tang (Angelica Sinensis Blood-Invigorating Decoction) is indicated as the primary formula.
Danggui Huoxue Tang (Angelica Sinensis Blood-Invigorating Decoction)
Danggui (Angelicae Sinensis Radix), Chuanxiong (Ligustici Chuanxiong Rhizoma), Chi Shao (Paeoniae Rubra Radix), Sheng Di (Rehmanniae Radix), Hong Hua (Carthami Flos), Zi Cao (Arnebiae Radix or Lithospermi Radix), Huang Qin (Scutellariae Radix), Huang Lian (Coptidis Rhizoma), Da Huang (Rhei Radix et Rhizoma).
Decoct in water and take orally.
[Folk Song] Jiawei Danggui Huoxue Tang is most effective for pustules that are dry and withered. It combines Siwu Tang (Four Substance Decoction) with Hong Hua (Carthami Flos) and Zi Cao (Arnebiae Radix or Lithospermi Radix), adding Huang Qin (Scutellariae Radix), Huang Lian (Coptidis Rhizoma), and raw Da Huang (Rhei Radix et Rhizoma).
Pu Hong (Spreading Redness) often occurs due to weak Yuan Qi (Original Qi), causing blood to fail to adhere to the pustules and allowing toxic pathogens to spread diffusely. The entire skin surface turns red, and the base of the pustules is bright red; this indicates a loss of Qi's controlling function, and the prognosis for the pustules is generally ominous. For Qi deficiency, Jiuwei Shengong San (Nine-Ingredient Divine Merit Powder) is used to tonify; for excessive toxicity, Liangxue Jiedu Tang (Blood-Cooling and Toxin-Resolving Decoction) is used to clear heat and resolve toxins.
[Note] During the inflation stage, blood fully adheres to the pustules, with a tight red line binding the base underneath; this is the normal form. If Yuan Qi (Original Qi) is weak and blood fails to adhere, toxic vapors scatter diffusely, resulting in bright purple-red coloration at the base on the skin surface. This signifies the loss of Qi's controlling power and often leads to untreatable conditions. If there is Qi deficiency with slight redness of the pustules, Jiuwei Shengong San (Nine-Ingredient Divine Merit Powder) is the primary formula; if toxicity is excessive with bright red bases, Liangxue Jiedu Tang (Blood-Cooling and Toxin-Resolving Decoction) is the primary formula.
Jiuwei Shengong San (Nine-Ingredient Divine Merit Powder)
Renshen (Ginseng Radix et Rhizoma), Huangqi (Astragali Radix, raw), Zicao Rong (Arnebiae Radix or Lithospermi Radix, fine hairs), Hong Hua (Carthami Flos), Qianhu (Peucedani Radix), Niubangzi (Arctii Fructus, stir-baked and ground), Gancao (Glycyrrhizae Radix et Rhizoma, raw), Baishao Yao (Paeoniae Radix Alba, wine-fried), Sheng Dihuang (Rehmanniae Radix Preparata).
Use large dates (Zao Ren) as a guide, decoct in water, and take orally.
