水姜煎服。
吴又可曰∶三承气汤，功用仿佛，热邪传里。但上焦痞满者，宜小承气汤。中有坚结者，
加芒硝软坚而润燥。病久失下，虽有结粪，然多粘腻，得芒硝则大黄有荡涤之能。设无痞
满，惟存宿结而有瘀热者，调胃承气汤宜之，三承气功效，皆在大黄，余皆治标之品，不耐
汤药者，或呕或哕，当为细末，蜜丸汤下。
如人方肉食，而病适来，以致停积在胃，用大小承气连下，惟是臭水稀粪而已，于承气
汤中，但加人参一味服之，虽三四十日所停之完谷及完肉，于是方下，盖承气借人参之力，
鼓舞胃气，宿物始动也。

大黄（五钱） 芒硝（二钱五分） 甘草（一钱）
用水和生姜煎煮后服用。
吴又可说：三承气汤，功效相似，用于热邪传入体内的情况。但如果上焦出现痞塞胀满的，适宜用小承气汤（小承气汤）。如果中有坚结的，加入芒硝以软化坚硬并滋润燥结。如果病程长久未及时攻下，即使有干结的粪便，大多也粘腻，得到芒硝则大黄就有荡涤清除的能力。假设没有痞塞胀满，只有宿便积结且有瘀热的，适宜用调胃承气汤（调胃承气汤），这三承气汤的功效，关键在于大黄，其余都是治标的药物，不能耐受汤药刺激的，或者呕吐或呃逆的，应当将药研成细末，用蜜制成丸剂，用汤药送服。
就像人刚吃了肉食，病恰好来了，导致食物停滞积聚在胃里，使用大小承气汤连续攻下，排出的只是臭水和稀粪而已，在承气汤中，只加入人参一味药服用，即使是停积了三四十天的完谷及完肉，也能被此方排出，这是因为承气汤借助了人参的力量，鼓舞胃气，宿积之物才开始移动。
白僵蚕（酒炒，二钱） 全蝉蜕（去土，一钱） 广姜黄（去皮，三分，不用片姜黄） 川大黄（生，四钱）
以上药材研成细末，混合研磨均匀，病情轻的分为四次服用，每次服用重一钱八分二厘五毫，用冷黄酒一杯，蜂蜜五钱，调匀后冷服，见效即止。病情重的分为三次服用，每次服用重二钱四分三厘三毫，黄酒一半，蜂蜜七钱五分，调匀后冷服。最重的，分为二次服用，每次服用重三钱六分五厘，黄酒二杯，蜂蜜一两，调匀后冷服。如果一二帖未痊愈，可以再服用，热退即止。孕妇和产妇也不忌用。炼蜜为丸，名为太极丸。药性稍缓和，必须空腹服用，服药后须禁忌半日不可喝茶水、抽烟、吃饮食，如果不能遵守禁忌，就没有效果，能遵守禁忌，咽下即苏醒，半天而愈。如果饱食后服用此药也没有效果，痊愈后最忌饱食，只宜吃稀粥四五分饱，永远不再复发。至于腥荤食物，更须切实牢固地禁忌，万万不可吃。
凡是患瘟疫，未曾服用其他药物，或者一两天，或者七八天，或者至一个多月未愈，只要服用此药，即可痊愈。如果先用其他药物无效，后用此药，也有偶尔不灵验的，是服药杂乱的原因。
杨栗山说：处方必须有君臣佐使，并且兼有引导，这是高明医生的大法。这个方子以僵蚕为君药，蝉蜕为臣药，姜黄为佐药，大黄为使药，米酒为引经药，连蜜为向导药，六种法则都具备，方子才完成。我曾考察本草，知道僵蚕味辛苦气薄，喜燥恶湿，得天地清化之气，轻浮而升，阳中之阳，所以能胜风除湿，清热解郁，从治膀胱相火，引轻清气上潮于口，散热浊结滞之痰。它的性质属火，兼土与木，老得金水之化，僵而不腐，温病火炎土燥，焚木烁金，得秋分之金气而自衰，所以能辟一切怫郁之邪气。蚕必三眠三起，眠者是病了，合身皆病，都不吃东西；起者是好了，合身皆好，都能吃东西。用此来治疗全家人的瘟疫病，所谓因其气相感，而以意使之者也，所以作为君药。蝉气寒无毒，味咸且甘，为清虚之品，出粪土之中，处极高之上，自甘风露而已，吸风得清阳之真气，所以能祛风而胜湿，饮露得太阴之精华，所以能涤热而解毒也。蜕者退也，大概是想让人退去其病，也像蝉脱壳一样无恙，也是所谓因其气相感，而以意使之者也，所以作为臣药。姜黄味辛苦温无毒，蛮人生吃，喜欢它祛邪伐恶，行气散郁，能入心脾二经，建功癖疫，所以作为佐药。大黄味苦，大寒无毒，上下通行，盖亢甚之阳，非此莫抑，苦能泻火，苦能补虚，一举而两得之，人们只知道它建立良将的大功勋，而不知道它有良相的硕德，所以作为使药。
米酒性大热，味辛苦而甘，令饮冷酒，希望它运行缓慢，传化逐渐进行，上行头面，下达足膝，外周毛孔，内通脏腑经络，驱逐邪气，无处不到，如物在高巅，必奋飞冲举以取之，物在远方及深奥之处，更必迅奔探索以取之，并且喜欢它和血养气，伐邪辟恶，仍是华陀旧法，也是屠苏之义，所以作为引经药。蜂蜜甘平无毒，其性大凉，主治丹毒斑疹，腹内留热，呕吐便秘，想要清其热，润燥而自散瘟毒，所以作为向导药。大概蚕吃而不喝，有大便无小便，蝉喝而不吃，有小便无大便，以清虚而散火，君明臣良，治化出焉。姜黄辟邪而靖疫，大黄定乱以致治，佐使同心，功绩建焉。酒引之使上行，蜜润之使下导，引导协力，远近通焉。补泻兼行，无偏胜之弊，寒热并用，得时中之宜，所谓天有覆物之功，人有代覆之能，其洵然哉，用治温病。百发百中，屡试屡验，万无一失。
Da Huang (Rhei Radix et Rhizoma) (5 qian), Mang Xiao (Natrii Sulfas) (2.5 qian), Gan Cao (Glycyrrhizae Radix et Rhizoma) (1 qian).
Decoct with water and fresh ginger for oral administration.
Wu Keyou stated: The three Chengqi Decoctions have similar functions, used when heat pathogens transmit to the interior. However, if there is fullness and obstruction in the upper jiao (Upper Burner), Xiao Chengqi Tang (Minor Order the Stomach Decoction) is appropriate. If there are hard accumulations in the middle, adding Mang Xiao softens hardness and moistens dryness. If the disease has persisted for a long time without proper purgation, even if there are hardened feces, they are often sticky; with Mang Xiao, Da Huang gains the ability to thoroughly cleanse. Assuming there is no fullness or obstruction, but only retained stool accumulation with stagnant heat, Tiao Wei Chengqi Tang (Order the Stomach and Regulate Harmony Decoction) is suitable. The efficacy of these three Chengqi Decoctions lies primarily in Da Huang; the others are merely symptomatic treatments. For those who cannot tolerate decoctions, or who experience vomiting or hiccups, the herbs should be ground into fine powder, formed into honey pills, and taken with warm water.
It is like a person who has just consumed meat, and illness strikes, causing food stagnation in the stomach. Using Da and Xiao Chengqi Decoctions consecutively results only in the expulsion of foul-smelling watery diarrhea. By adding just one ingredient, Ren Shen (Ginseng Radix), to the Chengqi Decoction, even fully digested grains and meat that have been retained for thirty to forty days can be expelled by this formula. This is because the Chengqi Decoction borrows the power of Ren Shen to stimulate stomach qi, causing the retained matter to move.
Bai Jiang Can (Bombyx Batryticatus) (2 qian, stir-fried with wine), Quan Chan Tui (Cicadae Periostracum) (1 qian, free of soil), Guang Jiang Huang (Curcumae Longae Radix) (0.3 qian, peeled, not Pian Jiang Huang), Chuan Da Huang (Rhei Radix et Rhizoma) (4 qian, raw).
Grind the above ingredients into a fine powder and mix evenly. For mild cases, divide into four doses; each dose weighs 1.825 liang (approx. 1 qian 8 fen 2 li 5 hao). Mix with one cup of cold yellow rice wine and 5 qian of honey, take cold after mixing well. Stop once the disease is cured. For severe cases, divide into three doses; each dose weighs 2.433 liang (approx. 2 qian 4 fen 3 li 3 hao). Use half a cup of yellow rice wine and 7.5 qian of honey, mix well and take cold. For the most severe cases, divide into two doses; each dose weighs 3.65 liang (approx. 3 qian 6 fen 5 li). Use two cups of yellow rice wine and 1 liang of honey, mix well and take cold. If not cured after one or two doses, it may be taken again. Stop when the fever subsides. It is not contraindicated for pregnant or postpartum women. Honey-pilled, named Taiji Wan (Taiji Pill). The nature is slightly mild. It must be taken on an empty stomach. After taking, one must abstain from tea, water, smoking, and food for half a day. If these taboos are not observed, it will be ineffective. If observed, recovery occurs immediately upon swallowing, and healing is complete within half a day. Taking this after a full meal is also ineffective. After recovery, overeating is strictly forbidden; only eat porridge until about 40-50% full to prevent recurrence forever. Spicy and strong-flavored foods must be strictly avoided at all costs.
For anyone suffering from plague (Wenyi), who has not taken other medicines, whether it has been one or two days, seven or eight days, or even over a month without cure, simply taking this medicine will result in recovery. If other medicines were tried first without effect, and then this medicine is used, there are occasional failures due to the confusion caused by mixed medications.
Yang Lishan said: A prescription must have Sovereign (Jun), Minister (Chen), Assistant (Zuo), and Courier (Shi) herbs, along with guiding agents; this is the great method of skilled physicians. In this formula, Bai Jiang Can is the Sovereign, Chan Tui is the Minister, Jiang Huang is the Assistant, Da Huang is the Courier, Rice Wine is the Guide, and Honey is the Director. All six methods are present, forming the prescription. I have studied the Materia Medica and know that Bai Jiang Can tastes bitter and pungent with a thin qi, preferring dryness and disliking dampness. It receives the clear transformative qi of heaven and earth, is light and floating, ascending, yang within yang. Thus, it can overcome wind and dispel dampness, clear heat and resolve depression, regulate the ministerial fire of the bladder, guide light clear qi to flood the mouth, and dissipate heat, turbid, knotted phlegm. Its nature belongs to fire, combining earth and wood. Aging, it undergoes transformation of metal and water, becoming stiff but not rotting. In warm diseases where fire flares and earth dries, burning wood and smelting metal, it naturally declines receiving the metal qi of the autumn equinox. Thus, it can repel all stifled pathogenic qi. Silkworms sleep and rise three times. Sleeping means sickness; the whole body is sick and does not eat. Rising means recovery; the whole body recovers and eats. Using this to treat plague in the whole family is called "due to the resonance of their qi, directing them by intention," hence it serves as the Sovereign. Chan Tui has a cold nature, is non-toxic, tastes salty and sweet, and is a pure and empty substance. It emerges from filth yet dwells high up, content with wind and dew. Absorbing wind, it obtains the true qi of clear yang, thus dispelling wind and overcoming dampness. Drinking dew, it receives the essence of yin, thus washing away heat and detoxifying. "Tui" means retreat; it aims to make the disease retreat, just as the cicada sheds its shell unharmed. This is also "due to the resonance of their qi, directing them by intention," hence it serves as the Minister. Jiang Huang tastes bitter, pungent, and warm, is non-toxic. Barbarians eat it raw, appreciating its ability to expel evil and attack malice, move qi and scatter depression. It enters the heart and spleen meridians, establishing merit against masses and plague, hence it serves as the Assistant. Da Huang tastes bitter, is greatly cold and non-toxic, circulating up and down. Excessive yang cannot be suppressed except by this. Bitterness can purge fire; bitterness can tonify deficiency, achieving two goals with one stroke. People only know its great merit as a good general but do not know its great virtue as a wise minister. Hence, it serves as the Courier.
Rice wine has a greatly hot nature, tastes bitter, pungent, and sweet. Drinking it cold makes it act slowly, transmitting gradually. It ascends to the head and face, descends to the feet and knees, circulates externally through pores, and internally connects zang-fu organs and meridians, driving out pathogenic qi everywhere. Like objects at high peaks, one must fly vigorously to retrieve them; objects in distant or profound places require swift pursuit. It also harmonizes blood and nourishes qi, attacks evil and repels malice, following Hua Tuo's old method and the meaning of Tusu Decoction. Hence, it serves as the Guide. Honey is sweet, neutral, non-toxic, and greatly cool in nature. It treats carbuncles, rashes, retained heat in the abdomen, vomiting, and constipation. To clear heat, moisten dryness, and naturally dissipate plague toxins, it serves as the Director. Silkworms eat but do not drink, having bowel movements but no urination. Cicadas drink but do not eat, having urination but no bowel movements. Using purity and emptiness to scatter fire, with a wise Sovereign and loyal Minister, governance arises. Jiang Huang repels evil and pacifies plague; Da Huang stabilizes chaos and achieves order. With Assistant and Courier united in heart, merits are established. Wine guides upward; honey moistens and guides downward. Guides cooperate, connecting far and near. Tonification and purgation proceed together, avoiding bias. Cold and hot are used together, achieving timely appropriateness. As heaven has the merit of covering all things, humans have the ability to substitute for heaven's covering. Truly so! Used to treat warm diseases. Hundred shots, hundred hits; repeatedly tested, repeatedly verified; absolutely safe.
