治疗中气虚弱，导致痘疹不能起发充盈。（《难经》说：气具有温煦的作用。所以气是嘘养生长万物的力量，痘疹不起是因为血弱。）
方剂见卷一上“治气门”
人参、白术、甘草用来补益中气，升麻、柴胡用来升举阳气，当归用来调和营血，陈皮用来理气顺气。
治疗痘症根部颜色淡白，属于血虚。（痘疹发展至五六日，是气盛血附的关键时期，根脚颜色淡说明血弱。因此使用当归活血，川芎行血，熟地黄补血，白芍收敛血液。）

治疗痘疮颜色紫暗干枯，使用此方凉血活血。
生地黄、当归、川芎、赤芍药、红花、紫草
颜色紫暗是因为血热，颜色干枯是因为血滞。热的要清凉它，干枯的要滋润它，这是调理血液的方法。生地黄是凉血的药物，其余药物都是活血的。
治疗表虚里实，气血皆虚弱。（在体表的表现是痘顶灰暗下陷为气虚，痘根颜色淡白为血虚，如果呼吸沉重气息粗大则为里实。）
人参、黄芪、甘草、当归、川芎、白芍药、厚朴、防风、白芷、肉桂、木香、桔梗
如果痘色红深黑陷，属于热毒者，去掉肉桂，加入紫草、红花、黄芩。如果痘色淡白灰陷，属于虚寒者，加入丁香温里，肉桂温阳。
因为气虚所以用人参、甘草，因为血虚所以用当归、白芍、川芎。然而防风、白芷、肉桂，能引导诸药从体内向外托举痘毒。
治疗气血两虚。（医学贵在预防未发生之病。痘症虽然顺遂，但如果身体气体虚弱，不补益恐怕会有后续的失误。因此使用四君子汤补气，四物汤养血。）

Treats deficiency of Middle Qi (Middle Jiao Qi), resulting in pustules failing to rise and swell. (*Nan Jing* states: "Qi provides warmth." Thus, Qi is the force that nurtures and grows all things; failure of pustules to rise is due to blood weakness.)
See Formula in Volume 1, Upper Section, Gate of Treating Qi.
Ren Shen (Ginseng Root), Bai Zhu (Atractylodes Rhizome), and Gan Cao (Licorice Root) are used to tonify Qi; Sheng Ma (Cimicifugae Rhizome) and Chai Hu (Bupleuri Radix) are used to raise Yang; Dang Gui (Angelicae Sinensis Radix) is used to nourish Ying (Nutritive) Blood; Chen Pi (Citri Reticulatae Pericarpium) is used to regulate Qi.
Treats pustule lesions with pale roots, indicating blood weakness. (When pustules reach five or six days, it is the time when Qi is abundant and Blood attaches; pale roots indicate blood weakness. Therefore, Dang Gui is used to invigorate blood, Xiong Huang (Ligusticum Rhizome) to move blood, Shu Di Huang (Rehmanniae Radix Preparata) to tonify blood, and Bai Shao (Paeoniae Radix Alba) to astringe blood.)
See Formula in Volume 1, Lower Section, Gate of Regulating Blood.
Treats pustules with purple and dry coloration, using this formula to cool blood and invigorate blood.
Sheng Di Huang (Rehmanniae Radix), Dang Gui, Chuan Xiong (Ligusticum Chuanxiong Rhizome), Chi Shao (Paeoniae Radix Rubra), Hong Hua (Carthami Flos), Zi Cao (Arnebiae Radix seu Lithospermi Radix).
Purple color indicates blood heat; dryness indicates blood stasis. Heat is cooled by cooling agents; dryness is moistened by moisturizing agents; this is the way to regulate blood. Sheng Di Huang is a blood-cooling herb; the remaining herbs all invigorate blood.
Treats exterior deficiency with interior excess, where both Qi and Blood are weak. (Exterior signs: gray, sunken pustule tops indicate Qi deficiency; pale pustule roots indicate Blood deficiency. If breathing is heavy and coarse, it indicates interior excess.)
Ren Shen, Huang Qi (Astragali Radix), Gan Cao, Dang Gui, Chuan Xiong, Bai Shao, Hou Po (Magnoliae Officinalis Cortex), Fang Feng (Saposhnikoviae Radix), Bai Zhi (Angelicae Dahuricae Radix), Rou Gui (Cinnamomi Cortex), Mu Xiang (Aucklandiae Radix), Jie Geng (Platycodonis Radix).
If the pustule color is deep red/black and sunken, indicating heat toxicity, remove Rou Gui, and add Zi Cao, Hong Hua, and Huang Qin (Scutellariae Radix). If the color is pale/white/gray and sunken, indicating deficiency-cold, add Ding Xiang (Caryophylli Flos) to warm the interior, and Rou Gui to warm Yang.
Because of Qi deficiency, Ren Shen and Gan Cao are used; because of Blood deficiency, Dang Gui, Bai Shao, and Chuan Xiong are used. However, Fang Feng, Bai Zhi, and Rou Gui can guide the various herbs from the interior to push outward.
Treats dual deficiency of Qi and Blood. (Medicine values prevention before disease arises. Although the pustule condition appears smooth, if the body's Qi is weak, failure to tonify may lead to subsequent complications. Therefore, Si Jun Zi Tang (Four Gentlemen Decoction) is used to tonify Qi, and Si Wu Tang (Four Substance Decoction) is used to nourish Blood.)
See Formula in Volume 1, Upper Section, Gate of Treating Qi, Supplementary Formula for Si Jun Zi Tang.
Treats deficiency-cold in the Stomach, or cases where cold-natured medicines were mistakenly taken, resulting in diarrhea and cold extremities.
See Formula in Volume 6, Lower Section, Gate of Dispelling Cold, Supplementary Formula for Li Zhong Tang (Regulate the Middle Decoction).
Treats pustule conditions lasting more than ten days, where Qi and Blood are weak.
See Formula in Volume 1, Upper Section, Gate of Treating Qi, Supplementary Formula for Si Jun Zi Tang.
