Di Huang (Rehmanniae Radix) and Mai Dong (Ophiopogonis Radix). This also embodies this principle.
Wang Shihiong's note: The methods for modifying these two formulas are most detailed in ancient texts.
Hua Xiuyun said: When the warm pathogen inside wants to erupt, and the new pathogen outside is added, Cong Chi Tang (Scallion and Fermented Soybean Decoction) is the most rapid and effective method, capable of restoring order to the exterior level (Biao Fen).
Zou Run'an said: Zhi Zi (Gardeniae Fructus) and Cong Bai (Allii Fistulosi Bulbus), one drains heat, the other unblocks Yang. Draining heat acts vertically; unblocking Yang acts horizontally. Vertical action can open the pathways between upper and lower, which is why it is suitable after sweating, vomiting, or purging, when exterior pathogens have been resolved. Horizontal action can reach the interior and exterior conditions, which is why it is suitable at the beginning of the disease when recognition is sudden and difficult. Dou Chi (Fermented Soybean) excels at opening depression in the Upper Jiao and guiding the stagnation of Yin turbidity, so whether before or after the onset, it is relied upon to achieve efficacy.
Wang Shihiong's note: Ye Tianshi, in his chapter on Spring Warmth, also advocates this formula for cases where a new pathogen triggers a latent pathogen. This decoction is an essential initial treatment for early-stage warm diseases. Ju Tong (Wu Jutong) failed to perceive this, abandoning the near for the distant, and was thus confused by Yu Shi's (Yu Chang's) speculative theories, treating Gui Zhi Tang (Cinnamon Twig Decoction) as the cure for initial contraction, still unable to step out of the Shang Han (Cold Damage) circle. If intending to inherit Zhong Jing (Zhang Zhongjing), one should not boast about ancestral achievements as one's own merits. Clinging to traces—is this true mental transmission? You Shi (You Yinheng) said: Gui Zhi Tang is established for Shang Han with exterior pathology but harmonious interior. Assuming warm disease latent cold transforms into heat, and the essence of Shao Yin has already been robbed, even if there is a combination of new and old pathogens, one must not use acrid-warm herbs to assist heat and sever the root. Did Wu Shi (Wu Jutong) perhaps not hear of this?

Qing Xin Liang Ge San (Clear Heart and Cool Diaphragm Powder) (also known as Jie Geng Tang)
This is Liang Ge San (Cool Diaphragm Powder) without Xiao Ming Piao (Natrii Sulfas) and Da Huang (Rhei Radix et Rhizoma), plus Jie Geng (Platycodonis Radix). Yu Shi further added Sheng Shi Gao (Gypsum Fibrosum), making it an excellent agent for treating the initial stage of epidemic rashes.

Wei Jing Tang (Reed Shoot Decoction)
Wei Jing (Arundinis Caulis) (2 jin), Yi Yi Ren (Coicis Semen), Gua Ban (Benincasae Semen, i.e., Winter Melon Seed) (each 0.5 jin), Tao Ren (Persicae Semen) (50 seeds).
Use 1 dou of water, first boil Wei Jing until 5 sheng remains, remove dregs; add other herbs, boil to obtain 2 sheng, take 1 sheng, then take again.
Wang Shihiong's note: Zou Shi's Continuation of Shu states: Wei Jing resembles lung tubes, is sweet and cool, clears the lungs, and being jointed and growing in water, it promotes circulation where fluids are blocked. It is especially effective in resolving harm caused by fluid obstruction. Yi Yi Ren is white and bland, cool in qi and descending in nature, embodying the full characteristics of autumn growth, nourishing Lung Qi to restore order. For damp-heat pathogens lodging in the lungs, this herb is indispensable. Gua Ban is Dong Gua Zi (Winter Melon Seed); since the seed attaches to the pulp which rots easily while the seed does not, it preserves vital energy amidst decay, thus effectively preserving vital energy amidst coagulated blood and deteriorated qi. Hence, it treats various abdominal abscesses and purges pus, blood, and turbid phlegm. Tao Ren enters the blood level to move Qi. Combined, this formula is not only a miracle drug for Lung Abscess but can also treat critical cases of Lung Bi (Lung Obstruction).

Xie Bai San (Drain White Powder)
Sang Bai Pi (Mori Cortex), Di Gu Pi (Lycii Cortex) (each 1 liang), Gan Cao (Licorice Root) (5 qian).
Make into coarse powder. Take 1–2 qian per dose, add 100 grains of Jing Mi (Oryza Sativa), and decoct with water.
Xu Huixi said: This formula treats fluid retention in the lungs.
Wang Shihiong's note: This is a formula that drains Lung Heat while securing Lung Qi. If the Lung is injured by Wind-Cold rather than Heat, as Ju Tong stated, it will surely lead to lingering pathogens gradually forming Lao Qie (consumptive cough). Therefore, medication must be prescribed based on the disease pattern first.

Ting Li Da Zao Xie Fei Tang (Descurainia Seed and Jujube Decoction to Drain the Lungs)
Ting Li Zi (Descurainiae Semen) (stir-fried until yellow, pounded into pills the size of a chicken egg), Da Zao (Jujubae Fructus) (12 pieces).
Use 3 sheng of water, boil Da Zao to obtain 2 sheng, remove dates; add Ting Li Zi, boil to obtain 1 sheng, take all at once.
Wang Shihiong's note: "Waitai" uses Ting Li Zi and Xing Ren (Praruni Semen) each 1 sheng, and 60 Da Zao, pounded into paste, mixed with honey into pills the size of tung tree seeds. Take 60–70 pills with Sang Bai Pi Decoction, stopping when bowels move freely. "Baoshi Fang" omits Xing Ren, adds Chen Pi (Citri Reticulatae Pericarpium) and Jie Geng, made into pills the size of tung tree seeds with date flesh. Take 5–7 pills with water, named Zao Gao Wan (Date Paste Pill). Yuan Rong added Ma Huang (Ephedrae Herba) and Wu Wei Zi (Schisandrae Fructus) to this formula. Wang's note: Using these two together seems cluttered. It treats wheezing and distension due to phlegm-fluid obstruction. I treat weak patients with excess-phlegm asthma by stir-frying Ting Li Zi until yellow, decocting, removing dregs, and boiling Da Zao in the decoction to eat. This is a method of transforming a harsh formula into a mild one.

Zhu Ye Shi Gao Tang (Bamboo Leaf and Gypsum Decoction)
Zhu Ye (Bambusae Folium) (2 handfuls), Sheng Shi Gao (Gypsum Fibrosum) (1 jin), Ban Xia (Pinelliae Rhizoma) (0.5 jin, washed), Ren Shen (Ginseng Radix) (3 liang), Gan Cao (Licorice Root) (2 liang, honey-fried), Mai Men Dong (Ophiopogonis Radix) (1 jin), Jing Mi (Oryza Sativa) (0.5 jin).
Wang Shihiong's note: Chen Xiuyuan said: In "Shang Han Lun," several formulas use Ren Shen. This is because after sweating, vomiting, or purging, body fluids are lost, so sweet-cool herbs are taken to rescue Yin.
Use 1 dou of water, first decoct the first six ingredients to obtain 6 sheng, remove dregs; add Jing Mi, cook until rice is done and soup is ready, remove rice, take 1 sheng warm, three times a day. "Ji Yan" adds Sheng Jiang (Zingiberis Rhizoma) to this formula, which is best for treating vomiting.
Wang Shihiong's note: I use this formula to treat Summerheat Malaria with excellent results.
Xu Huixi said: This is a follow-up treatment for deficiency and emaciation with shortness of breath after the resolution of Shang Han. After a major illness, residual heat must remain; treatment should clear and nourish. Later generations generally used harsh tonics to retain pathogens, so Yuan Qi cannot recover suddenly; the more they tonify, the weaker they become.
Wang Shihiong's note: Only Yu Shi understood this principle; Ye Shi mastered it.

Qing Zao Jiu Fei Tang (Clear Dryness and Rescue the Lungs Decoction)
Jing Shuang Sang Ye (Mulberry Leaf Frosted by Autumn) (3 qian, remove veins), Xing Ren (Apricot Seed) (7 fen, remove skin and tips, stir-fry until yellow), Mai Men Dong (Ophiopogonis Radix) (1.2 qian), Sheng Shi Gao (Gypsum Fibrosum) (2.5 qian), Ren Shen (Ginseng Radix) (7 fen), E Jiao (Donkey-hide Gelatin) (8 fen), Hu Ma Ren (Sesami Semen) (1 qian), Pi Pa Ye (Loquat Leaf) (remove hairs and veins, 1 piece), Gan Cao (Licorice Root) (1 qian).
Use 1 bowl of water, decoct to 0.6 bowl, take far from meals. For excessive phlegm, add Bei Mu (Fritillariae Bulbus) and Gua Lou (Trichosanthis Radix); for blood dryness, add Sheng Di (Rehmanniae Radix Preparata); for severe heat, add Xi Jiao (Rhinocerotis Cornu), Ling Yang Jiao (Capricornis Cornu), or Niu Huang (Bovis Calculus).
Ke Yunbo said: Ancient formulas used aromatic-dry herbs to treat Qi stagnation without effect because fire follows dryness. Only Miao Zhongchun understood this, thus using sweet-cool and moistening herbs to clear Metal and protect the Lungs. Yu Shi followed this principle, gathering various moistening agents to create this decoction, with profound intent. Wang's note: This is a divine formula for Autumn Dryness syndrome, far superior to Dong Yuan's Qing Zao Tang.

Miao Xiang Wan (Wonderful Fragrance Pill) (also known as Da Sheng Wan)
Ba Dou (Crotonis Fructus) (315 grains, remove skin, heart, and membrane, stir-fry until cooked and grind like flour), Niu Huang (Bovis Calculus) (ground), Ni Fen (Calomelas) (ground), Long Nao (Borneolum Syntheticum) (ground), She Xiang (Moschi Feratum) (ground, each 3 liang), Chen Sha (Cinnabaris) (flying, 9 liang), Jin Bo (Gold Foil) (90 sheets, ground). Grind uniformly, refine 6 liang of Huang La (Beeswax), add 3 fen of Bai Mi (Honey), refine together until uniform, make into pills. Each liang makes 30 pills, take 2 pills with white water, twice daily. "Xuan Ming" contains Shui Yin (Mercurius) and Peng Sha (Borax).
This pill treats various convulsions and epilepsy, also treats tidal fever and accumulated heat from Shang Han, chest binding with jaundice, manic running and restlessness, and blockage of stool and urine. Xu Shi said: One pill divided into three parts is hard to swallow; better to divide into one part per pill, taking 3 pills per dose is appropriate.

Liu Yi San (Six-to-One Powder) (also known as Tian Shui San)
Ni Bai (referring to fine white滑石), Hua Shi (Turmalini Silicatis Gemma) (6 liang, water-flown), Gan Cao (Licorice Root) (1 liang, honey-fried). Make into fine powder. Take 3 qian per dose, mix with warm water or fresh well water, three times daily. For internal invasion of Summerheat-Dampness and external attack of Wind-Cold, take 50 Dou Chi (Fermented Soybean) and 5 cun of Cong Bai (Allii Fistulosi Bulbus), decoct in 1 sheng of water to make juice, mix and take; relief follows. Severe cases resolve in three doses. To induce labor and promote lactation, mix with Sesame paste in warm water; it can also expel dead fetus and resolve Blister Beetle toxicity. Add a little Chen Sha (Cinnabaris), named Yi Yuan San; add a little Huang Dan (Minii Oxidum Rubrum), named Hong Yu San; add a little Qing Dai (Indici Folium), named Bi Yu San; add a little Bo He Ye (Menthae Haplocalycis Folium) powder, named Ji Su San.
Li Binhu said: When heat disperses, the Three Jiao calms, and interior and exterior harmonize; when dampness leaves, the Lan Gate opens, and Yin and Yang flow smoothly. Wan Su used it to treat over seventy syndromes, praising it as an immortal medicine among mortals, indispensable.
Wang Shihiong's note: Do not take if urination is clear and long.

Da Shun San (Great Harmony Powder)
Gan Cao (Licorice Root) (30 jin, cut into inch-long pieces), Gan Jiang (Zingiberis Rhizoma), Xing Ren (Apricot Seed) (remove skin and tips), Rou Gui (Cinnamomi Cortex) (remove rough bark, each 4 jin). First stir-fry Gan Cao with Bai Sha (White Sand) until eight parts yellow and cooked. Wang Jinshan said: Bai Sha is river sand. Some say it is white sugar, which is incorrect. Then add Gan Jiang and stir-fry until ginger cracks; then add Xing Ren and stir-fry until no sound is heard, sieve off sand, then add Rou Gui and pound into powder. Take 2 qian per dose, decoct in water and take warm. If irritable, mix with Jing Hua Shui (Well Water drawn at dawn), time不限, boiling water is also acceptable.
Wang Andao said: In this formula, Gan Cao is most abundant, followed by Gan Jiang, Xing Ren, and Rou Gui. Except for Rou Gui, the other three are stir-fried because the original intention was for people exposed to summer heat with latent heat, drinking excessively. Spleen and Stomach affected by dampness, vomiting undigested food and water, disharmony of Zang-Fu. It is essentially a warming herb formula; Xing Ren is included merely for its ability to direct Qi downward. If used to treat syndromes acquired from stillness (cooling down), I fear it will not resolve the condition but increase internal irritability. The ignorant classify it as essential for summer because "Yin Qi is inside." Alas! Error. Yin Qi is not Cold Qi. In summer, Yang Qi disperses outward, while Yin Qi stays inside! How can Yin Qi be viewed as Cold Qi and treated with warm-hot herbs? If Yin were truly Cold, why drink water in summer? Wang's note: If summer requires warm herbs, must winter require cool herbs? Moreover, with great heat and irritability, adding the drying heat of Ginger and Cinnamon is problematic. Resorting to Jing Hua Shui to balance them shows insufficient power to control the heat, leaving one without footing.
Xu Huixi said: This treats internal injury from cold drinks in summer, not Summerheat itself. Also, having Gan Cao eight times more than other herbs is not standard practice. Such cases are rare; occasional use is fine. But preparing 42 jin of medicine to take only 2 qian—what is the purpose? This formula is not worth adopting, yet mediocre doctors use it to treat dry-fire Summerheat diseases, killing countless people, how mournful!

Zi Xue Dan (Purple Snow Pellet)
Huang Jin (Aurum) (100 liang, Xu says: replacing with 10,000 sheets of flying gold is even better), Han Shui Shi (Halloysitum), Ci Shi (Magnetitum), Shi Gao (Gypsum Fibrosum), Hua Shi (Turmalini Silicatis Gemma) (each 3 jin).
Crush all above, use 1 hu of water, boil to 4 dou, remove dregs, add next drugs:
Ling Yang Jiao (Capricornis Cornu), Xi Jiao (Rhinocerotis Cornu), Qing Mu Xiang (Aquilariae Lignum Resinatum), Chen Xiang (Aquilariae Lignum) (each 5 jin), Ding Xiang (Caryophylli Flos) (1 liang, Xu says: 2 liang is better), Yuan Shen (Scrophulariae Radix), Sheng Ma (Cimicifugae Rhizoma) (each 1 jin), Gan Cao (Licorice Root) (8 liang, honey-fried).
Add to previous decoction, boil to obtain 1.5 dou, remove dregs, add next drugs:
Pu Xiao (Natrii Sulfas), Xiao Shi (Natrii Nitras) (4 jin, Xu says: two salts are too much, use one-tenth).
Add these two to previous decoction, simmer on low fire, stir constantly with willow wood spatula, when reduced to 7 sheng, pour into wooden basin, let stand for half a day until congealing, add next drugs:
Zhu Sha (Cinnabaris) (3 liang), She Xiang (Moschi Feratum), Dang Men Zi (Moschi Feratum) (1.25 liang).
Mix these two into previous medicine, stir evenly, store in porcelain vessel. Medicine becomes frosty snow-like and purple color, mix with fresh well water and take.
Wang Shihiong's note: "Ji Feng" formula lacks Ci Shi, Hua Shi, Xiao Shi; uses only 10 liang each of the two horns, 5 liang each of Ding, Chen, Mu Xiang, 6 liang Sheng Ma, 2 jin Pu Xiao, but 3 liang She Xiang, remaining six ingredients same. Xue Gongwang says: Gold in the formula is optional. Wang's note: Flying gold foil should be used and not removed.
Xu Huixi said: Evil fire and toxic fire penetrating meridians and entering viscera have no cure. This can dissolve them, with miraculous efficacy.

Yu Yu Liang Wan (Yu Yu Liang Pill) (also known as Zhen Sha Wan, or She Han Shi Wan)
She Han Shi (Snake-containing Stone, i.e., large Snake Yellow) (3 liang, place in new iron pot, burn in charcoal fire until stone and pot are equally red, take out with tongs, pour Snake Yellow into vinegar, wait until cool, grind to extremely fine powder, set aside), Yu Yu Liang (Haematitum) (3 liang), Zhen Zhen Sha (Real Needle Sand) (5 liang, wash clean with water, stir-fry dry, put with Yu Yu Liang, use 2 sheng Rice Vinegar, boil in pot until vinegar dries, then put pot and medicine back in charcoal fire until red, take out with tongs, pour medicine onto clean brick, wait until cool, grind fine). Use these three as main ingredients, then add following herbs according to patient's deficiency or excess:
Qiang Huo (Notopterygii Rhizoma et Radix), Chuan Xiong (Ligustici Chuanxiong Rhizoma), Mu Xiang (Aucklandiae Radix), Fu Ling (Poria), Niu Xi (Achyranthis Bidentatae Radix), Gui Xin (Cinnamomi Ramulus), Bai Dou Kou (Amomi Fructus Rotundus), Da Hui (Foeniculi Fructus), Peng Zhu (Curcumae Rhizoma), Fu Zi (Aconiti Lateralis Radix Preparata), Gan Jiang (Zingiberis Rhizoma), Qing Pi (Citri Reticulatae Pericarpium Viride), San Leng (Sparganii Rhizoma), Bai Ji Li (Tribuli Fructus), Dang Gui (Angelicae Sinensis Radix) (soaked in wine overnight, each 5 qian).
Make into powder, mix with previous medicine, soak steamed cake in water, squeeze out water, mix with medicine; pound again, make into pills the size of tung tree seeds. Take 30–50 pills before meals with warm wine or white water. Strictly avoid salt; do not let any enter the mouth, otherwise disease worsens. Upon taking medicine, it passes quickly through urine, does not disturb Zang-Fu, but removes disease, take three times daily. Assist with mild Qi and Blood tonifying herbs; truly a divine formula.
Wang Shihiong's note: This is a formula for edema and cold accumulation; nowadays people use it for distension. However, distension has cold and heat patterns; if heat distension is mistakenly treated, harm is significant. Danxi said: Too many warm-hot herbs, modifications are needed, do not rigidly stick to the formula. Wei Yuheng said: Yin deficiency with internal heat causing distension, mistakenly taking drying-hot stone medicines will cause death.
Xu Huixi said: This formula also treats tangible accumulations.

Mu Li Ze Xie San (Oyster and Alisma Powder)
Mu Li (Ostreae Concha), Ze Xie (Alismatis Rhizoma), Shu Qi (Patriniae Herba) (wash to remove fishy smell), Gua Lou Gen (Trichosanthis Radix), Ting Li Zi (Descurainiae Semen), Shang Lu Gen (Phytolaccae Radix) (stir-fried), Hai Zao (Sargassum) (wash to remove saltiness, equal parts). Pound separately, sift into powder, then pound in mortar again. Mix with white drink (rice water) and take one cubic inch spoon. Stop subsequent doses when urination becomes smooth.
Wang Shihiong's note: Ancients said: Shang Lu decocted in water can kill.
Hua Xiuyun said: Ye Shi skillfully used ancient formulas but only took their principles without sticking rigidly; observe his subtle modifications, such as in Fu Mai, Jian Zhong, Xie Xin, etc. Regarding the use of Mu Li Ze Xie San, he only took these two ingredients. Thus, in cases where only the formula name is written without listing ingredients, it definitely does not mean using the original formula entirely; there must be modifications. Readers should understand this by implication.
Wang Shihiong's note:
This discussion is extremely thorough; all formulas should be viewed similarly.
Zou Run'an said: In Mu Li Ze Xie San syndrome, water accumulates below, and Upper Jiao Qi cannot transform it. Thus, "Lei Cui" uses Shang Lu and Ting Li to descend from above, Ze Xie and Hai Zao to raise clear Qi from water, Gua Lou and Mu Li one to aid clarity above, one to summon turbidity below, thereby facilitating transformation.
He also said: Mu Li Ze Xie San treats water Qi failing to move below the waist. First, Shang Lu and Ting Li must open the source blockage from Lung and Kidney. Then, the softening hardness of Mu Li and Hai Zai, and the opening and draining of Shu Qi and Ze Xie can take effect. Gua Lou Gen is used fearing that the Qi moving water might be too rapid, injuring Upper Jiao Yin. It causes Yin to be absorbed from Spleen and returned upward, similar to the snake of Chang Shan, striking the head makes the tail respond, striking the tail makes the head respond.

Yue Pi Tang (Disperse Spleen Decoction)
Ma Huang (Ephedrae Herba) (6 liang), Shi Gao (Gypsum Fibrosum) (8 liang), Sheng Jiang (Zingiberis Rhizoma Recens) (3 liang), Gan Cao (Licorice Root) (2 liang), Da Zao (Jujubae Fructus) (12 pieces).
Use 6 sheng of water, boil Ma Huang to remove foam; add other herbs, boil to obtain 3 sheng, divide into three doses. For aversion to wind, add 1 Fu Zi (Aconiti Lateralis Radix Preparata).
Yu Jiayan said: Yue Pi Tang indicates a formula for slight release without actual sweating. Generally, it aims to regulate Ying and Wei. Ma Huang and Shi Gao, one sweet-warm, one sweet-cool, combined together: if Spleen leans toward Yin, harmonize with sweet-warm; if Stomach leans toward Yang, harmonize with sweet-cool. Even Wind-Heat Yang and Water-Cold Yin, anything disharmonious in Middle Earth can use this. Why? If Middle Earth is disharmonious, grain and water do not transform their refined Qi to fill Ying and Wei. If Ying and Wei are deficient, Cold or Heat Qi can block tunnels, failing to connect interior and exterior. Therefore, it is used for exterior Wind-Water, and for interior Water with thirst and free urination, all aiming to not harm Middle Earth. Not harming Middle Earth naturally eliminates trouble at its萌芽 (sprouting).

Gan Suan Ban Xia Tang (Kansui and Pinellia Decoction)
Gan Suan (Kansui Radix) (3 large pieces), Ban Xia (Pinelliae Rhizoma) (12 pieces), Shao Yao (Paeoniae Radix Alba) (5 pieces), Gan Cao (Licorice Root) (1 piece finger-sized, some versions omit Gan Cao).
Wang's note: Although Wang Shi explained it, one should follow the version omitting Gan Cao.
Use 2 sheng of water, boil to obtain 0.5 sheng, remove dregs; mix with 0.5 sheng of Honey, decoct medicine juice to 0.8 sheng, take all at once.
Wang Jinshan said: Gan Suan opposes Gan Cao. Opposing means this one wants to descend while that one wants to ascend. Thus, Shao Yao constrains it, and Honey moistens it, so although opposing, Gan Suan still penetrates downward. "Ling Shu" says: Restricting a formula is like restricting a bag. Gan Suan and Ban Xia chase lingering fluid overflowing in intestines and stomach; even if purged, hardness and fullness continue. Unless stimulated by Gan Cao and Honey which greatly oppose Gan Suan, how can the rooted lingering cause be removed? Formulas using opposition rely entirely on Shao Yao's sourness overcoming sweetness, constraining to supervise opposition, lest chaos in Middle Jiao cause harm. However, those with inferior learning should not lightly test this on others.

Kong Xian Dan (Control Phlegm Pellet) (also known as Miao Ying Wan)
Gan Suan (Kansui Radix) (remove heart), Da Ji (Euphorbiae Pekinensis Radix) (remove skin), Bai Jie Zi (Sinapis Semen) (equal parts).
Make into powder, make pills with steamed cake paste. Take 5–7 to 10 pills per dose, take with Ginger Water before sleep.
Wang Shihiong's note: I treat fluid retention in weak persons, often sending it with Liu Jun Zi Tang (Six Gentlemen Decoction) minus Gan Cao, which is very appropriate. Da could call it Zi Long Wan. It says: Very effective for flowing abscesses and wandering toxins.
Wang Jinshan said: Kong means guide. Xian is read as Xian, meaning flowing saliva/water appearance. Guiding Water of Three Jiao, flowing saliva out through water passages. Jie Zi is white, enters Lung and reaches Upper Jiao. Gan Suan is yellow, enters Spleen and moves Middle Jiao. Da Ji is black, enters Kidney and goes to Lower Jiao. Thus, Bai Jie Zi moves water-fluid in skin and membranes; Gan Suan breaks water-fluid in meridians; Da Ji chases water-fluid in Zang-Fu. The three guide meridians differently, but flow saliva through water passages is the same, hence combining them as a formula named Kong Xian. Wang's note: Xian is a vulgar character for Ci, also written as Xuan, originally referring to mouth saliva, extended to phlegm-saliva. Wang's explanation is inappropriate.
Another Kong Xian Dan treats various epilepsies.
Sheng Chuan Wu (Aconiti Kusnezoffii Radix), Ban Xia (Pinelliae Rhizoma) (washed), Jiang Can (Bombyx Batryticatus) (stir-fried, each 0.5 liang, soaked overnight in Ginger Juice), Tie Fen (Ferrum Oxydatum Rubrum) (3 qian, ground), Quan Xie (Scorpio), Gan Suan (Kansui Radix) (wrapped in dough and baked, each 2.5 qian).
Make into fine powder, make pills with natural Ginger Juice, size of mung beans, coat with Zhu Sha (Cinnabaris). Take 15 pills per dose with Ginger Water. Both formulas forbid eating Gan Cao.

Wu Zi Wu Pi Tang (Five Seeds and Five Peels Decoction)
That is Wu Pi Yin (Five Peels Decoction) (Wu Jia Pi (Acanthopanacis Cortex), Di Gu Pi (Lycii Cortex), Fu Ling (Poria), Da Fu Pi (Arecae Pericarpium), Sheng Jiang Pi (Zingiberis Pericarpium); one version replaces Wu Jia with Chen Pi; another replaces Wu Jia with Sang Bai Pi (Mori Cortex)) plus Xing Ren (Apricot Seed), Su Zi (Perillae Fructus), Ting Li Zi (Descurainiae Semen), Bai Jie Zi (Sinapis Semen), Lai Fu Zi (Radish Seed). One version lacks Xing Ren and Jie Zi, has Xiang Fu (Cyperi Rhizoma) and Che Qian Zi (Plantaginis Semen).

Gui Ling Wan (Cinnamon and Poria Pill)
Gui (Cinnamomi Ramulus) (1 liang), Fu Ling (Poria) (2 liang).
Make into powder, honey pills. Take 2 qian with boiling water. Made into decoction, named Gui Ling Yin.

Yu Gong Wan (Yu Gong Pill) (also known as Yu Gong San)
Hei Qian Niu Tou (Black Morning Glory Seed Head) (ground once, not re-ground, 4 liang), Da Hui (Foeniculi Fructus) (stir-fried, 1 liang).
Make into fine powder. Mix with natural Ginger Juice and take 1–2 qian. Or add 1 liang Mu Xiang (Aucklandiae Radix).

Fang Ji Fu Ling Tang (Stephania and Poria Decoction)
