Cardamomi Fructus (2.5 qian each), Dingxiang (Caryophylli Flos), Banxia (Ginger-processed), Fuzii Radix et Rhizoma Praeparata (Pao, peeled; 1.5 qian each).
Crush the above herbs. Take 2 qian per dose, add one lamp of water, five slices of fresh ginger, and three jujubes, decoct and take orally.
This formula treats deficiency-cold syndrome. (For cases with deficiency but no cold, the preceding formula for dual deficiency of qi and blood is suitable; this formula should not be used. It can only be used when the pulse is deficient and fine, and the limbs and body are cold.)

Shibu San (Ten-Tonifying Powder): Nourishes qi and blood, regulates spleen and stomach, and facilitates the rapid eruption of toxin in sores. Use it if there are cold signs. Adding Zicao (Arnebiae Radix seu Cortex), Muxiang (Aucklandiae Radix), and Nuomici (Oryza Sativa Glutinosa Semen) is called Shen Neituo San.
Huangqi (Astragali Radix), Renshen (Ginseng Radix), Danggui (Angelicae Sinensis Radix) (2 qian each), Houpo (Magnoliae Officinalis Cortex), Jiegeng (Platycodonis Radix), Chuanxiong (Ligustici Chuanxiong Rhizoma), Fangfeng (Saposhnikoviae Radix), Baizhi (Angelicae Dahuricae Radix), Gancao (Glycyrrhizae Radix et Rhizoma) (1 qian each), Guixin (Cinnamomi Ramulus) (3 fen).
Take 4 qian per dose, decoct in water and take orally; or grind into powder and mix with warm water to take 1.5 qian.

[Deficiency-Heat Example]
Langen San (Isatidis Root Powder): Treats slow eruption of sores/rashes and inverted crusting (retraction of pustules). Also known as Ersheng San, used to save critically ill children.
Banlangen (Isatidis Radix) (1 liang), Gancao (Licorice Root, honey-fried) (7.5 qian).
Grind into fine powder. Take half a qian per dose, mix with three to two drops of rooster comb blood and a little warm wine, take after meals, at any time. For severe cases, take three to five doses for immediate effect. (Danxi said: Lan root can disperse stagnant blood.)

Sigua San (Luffa Powder): Most excellent for promoting the eruption of sores/rashes. Burn luffa fruit with skin to ash, preserving its medicinal property. Mix with boiling water to take. Alternatively, decoct Zicao (Arnebiae Radix seu Cortex) and Gancao (Glycyrrhizae Radix et Rhizoma) to mix and take; rice soup is also acceptable.
Luobo Tang (Radish Decoction) (see previous text).

[Irrestlessness and Insomnia Example]
For smallpox/rash patients with irritability and inability to sleep, use Ganjie Jia Zhizi Tang (Licorice and Platycodon Decoction plus Gardenia).
Jiegeng (Platycodonis Radix), Gancao (Glycyrrhizae Radix et Rhizoma), Zhizi (Gardeniae Fructus).
Equal parts of the above, decoct and take.

[Huo] For smallpox/rash with slow eruption, irritability, and insomnia, treat with Shuijie San, Mahuang Huangqin Tang, or Shengma Huangqin Tang. (Haizang said: It is better to determine the state of qi and blood and use Shi Gao (Gypsum Fibrosum) and Zhizi (Gardeniae Fructus), which is especially good. Mahuang Huangqin Tang and Shengma Huangqin Tang should only be used after confirming Taiyang and Yangming syndromes.)

Shuijie San (Water-Resolving Powder): Treats epidemic headache and high fever for one to two days; also treats irritability before sore eruption, or continued fever after eruption.
Mahuang (Ephedrae Herba, nodes removed) (4 liang), Dahuang (Rhei Radix et Rhizoma), Huangqin (Scutellariae Radix), Guixin (Cinnamomi Ramulus), Gancao (Glycyrrhizae Radix et Rhizoma, honey-fried), Shaoyao (Paeoniae Radix Alba) (2 liang each).
Grind into coarse powder. After the patient bathes in a mixture of raw and boiled water, take 2 qian mixed with warm water. Follow with a second dose. Recovery occurs with sweating and unobstructed bowel movement. Strong individuals take two fangcunbi (square-inch scoops). Individuals with wind-excess constitution may also use it during the dog days of summer. If Dahuang is omitted, it is suitable for spring and summer.

Shengma Huangqin Tang (Codonopsis and Scutellaria Decoction): Treats slow eruption of smallpox/rash, irritability, and insomnia. Mahuang Huangqin Tang treats slow eruption of smallpox/rash with increased irritability and drowsiness, or body pain and fever after eruption. (Both formulas are found in the Pediatric Cold Damage section.)

Huwu Jiu (Coriander Wine): Use only Coriandrum sativum Herb (Husu). Finely chop 4 liang, add two lamps of good wine, boil for one or two boils, add Husu again and boil briefly. Cover tightly, let cool to warm. Inhale a large mouthful and spray gently from head to toe evenly, avoiding the head and face. Keep the patient surrounded by the aroma of Husu to dispel foul qi and promote rapid eruption of sores/rashes.

The "Zhinan" mentions the prohibition of treating sores, stating that the collapse of smallpox toxin is due to weak qi and blood failing to contain the toxin, causing the toxin to accumulate where the couli (interstices) are empty. Thus, when smallpox first erupts, one or two spots may appear in hidden interstitial joints or between the limbs. Once these spots erupt, other spots cannot develop properly into pustules, hence called "Prohibited Sores." There are five prohibitions: Stomach Prohibition, Fire Prohibition, Water Prohibition, Wind Prohibition, and Cold Prohibition.
Stomach Prohibition: Toxic fire scorches the stomach, preventing dispersion to the muscle surface, leading to spleen and stomach ulceration. Externally, sores appearing on the lips and mouth, such as two to five connected spots, where other sores have not yet formed pus while this spot has already turned yellow and matured, indicates internal attack by heat-toxin and rotting of the stomach, preventing other sores from forming pus. Upon seeing such sores on the lips/mouth, observe if the complexion is flushed red, breathing is coarse and hot, and breath is unusually foul; this confirms the diagnosis.
Fire Prohibition: At the initial stage of onset, if the child has chills and fever and is mistakenly fumigated with fire or sleeps in a heating box, drying the skin, the toxin cannot be excreted. Combined with qi deficiency failing to contain the toxin, the toxin stays within the skin, faintly unable to emerge. Carefully observing the skin reveals red spots without heads or feet, or one or two spots in broad areas of limbs/head/face. Other sores then erupt destructively from these spots, and the faintly hidden sores fail to erupt quickly, named Fire Prohibition. Bathing with Yangliu (Salix Twig) plus Jingjie (Schizonepetae Herba) decoction allows other sores to erupt naturally; mild cases are treated with Shengma Hejie San.
Water Prohibition: At the initial fever stage, when yin and yang are undifferentiated and toxin is strong, mistaken consumption of cold/raw food causes toxin to stay between skin and flesh, showing faint red spots or blisters in broad areas of ribs/hands/feet/head/face. Internal cold causes abdominal pain and distension; external cold causes fever and aversion to wind, confirming the diagnosis. Expel using Ding (Dingxiang), Gui (Rougui), Fuling (Poria), Shengma (Cimicifugae Rhizoma), Dafu (Arecae Pericarpium), etc. Prevent diarrhea from cold food retention in spleen/stomach by adding Shanzha (Crataegi Fructus).
Wind Prohibition: At the onset of fever, failure to avoid wind allows wind to enter the muscle surface, preventing eruption. Symptoms include numbness of skin without pain/itch sensation, or dryness, straight/dry hair, itchy skin wanting to scratch, or severe mania and delirium due to wind-fire binding. Treatment: Use Shengma Tang plus Qianghuo (Notopterygii Rhizoma et Radix) and Jingjie (Schizonepetae Herba) to expel; for severe cases, use Jili (Tribuli Fructus) and Chantui (Bombyx Dispar Cicadae Periostracum) to attack.
Cold Prohibition: At the onset of fever, mistaken bathing in cold water, sleeping on iron/paint cold surfaces, or thin clothing exposing to cold causes smallpox to fail to emerge. Symptoms include numb hands/feet without pain/itch, cold painful limbs immobile, no sores in numb/cold painful areas, but sores appearing like urticaria in sheltered areas or hairline. This confirms the diagnosis. Internally expel with Ding (Dingxiang), Gui (Rougui), Chuanxiong (Ligustici Chuanxiong Rhizoma), Shengma (Cimicifugae Rhizoma); externally warm with cotton clothes. I once saw an 11-12 year old child who slept on a newly lacquered bed during initial fever. Parents did not anticipate smallpox, allowing the child's hand to touch the lacquer bed, causing cold qi to invade the arm. Sores appeared on other limbs/face/abdomen, but the arm was numb with no sores. Doctors did not know the cause. Upon my examination, I treated with the aforementioned formula. Later, the arm erupted with denser sores than elsewhere. Once arm sores emerged, all other sores rose, and recovery occurred in nine days.
