Wu Youke treated pregnant women suffering from plague using San Chengqi Tang (Three Inheriting Decoctions, a formula for purging heat and accumulation), achieving benefit and eliminating harm within a very short time, which was already excellent. However, Mangxiao (Natrii Sulfas) should be removed from the prescription. This is because Mangxiao is a substance that softens hardness; its use could cause the fetus to dissolve into fluid. If symptoms of pi (glomus), man (fullness), zao (dryness), shi (excess), and jian (hardness) are all present, one may use Sheng Dahuang (Raw Radix et Rhizoma Rhei) at most and then stop; otherwise, it is more appropriate to use only Shu Jun (Prepared Radix et Rhizoma Rhei). The fetus and the intestines and stomach are absolutely unrelated. Although Dahuang can cleanse the intestines and stomach and break up hardness and dryness, there is no record of it causing abortion. What harm would there be in taking it? As for the claim that Dahuang is the sacred medicine for calming the fetus, this statement applies specifically to cases with interior excess syndromes requiring purgation. If the pathogenic factor remains in the exterior, one should rapidly disperse the exterior pathogen to prevent it from sinking inward, which is the superior treatment method.

HT Ta San: Used for pregnant women suffering from plague, fearing damage to fetal qi.
Nen Juan Heye (Dried tender coiled lotus leaf, preferably stored in advance; if needed urgently, dry it by heating, dosage 5 qian), Bangfen (Concha Tridacnidae, dosage 2.5 qian).
Grind the above together into fine powder. For each dose, mix with fresh well water and honey, take 3 qian orally. Prepare another dose to apply topically on the abdomen.

Another prescription: Apply mud from the bottom of a well to the soles of the feet. Treats fetal restlessness caused by seasonal epidemic diseases during pregnancy.

Another prescription: Use soil from the center of the stove base around the pot's rim, grind finely, mix with water for oral administration, and simultaneously apply to the umbilicus. Replace when dry.

Tumi San (Umbilical Application Powder): Composed of Jingdi Ni (Mud from the bottom of a well), Qingdai (Indigo Naturalis), and Fulonggan (Caulis Longan or Dragon Bone depending on context, here likely Arsenolite or similar earthy substance used in folk remedies, literally "Dragon Sitting Liver"), ground together and mixed evenly. Apply to the umbilicus. Replace when dry.

Huangdou Jian (Soybean Decoction): 60 large soybeans, add two zhong of water, decoct until one zhong remains. Induce sweating. If the condition is severe, administer another dose.

Pregnancy febrile disease: Chegu Zhi (Grease from chariot wheel axles) taken with Huangjiu (Yellow wine).

Qingyangshi (Excrement of black sheep) ground into a paste, applied to the umbilicus to calm the fetus.

Another prescription: Take ten chicken eggs, immerse them in a well until cold, remove, crack open, and swallow to stabilize the fetus.

Pregnancy complicated by seasonal epidemic qi and cold invasion: Take one large crucian carp, burn until carbonized but retaining medicinal properties, grind finely, and wash down with Huangjiu. If there is no sweat and abdominal heat pain, mix with vinegar and take to induce sweating.

Febrile disease: Ge Gen juice (Puerariae Lobatae Radix juice) taken frequently.

During times of rampant plague, if children exhibit symptoms such as fever, one might tentatively diagnose plague. However, in years when plague is not prevalent, and a child suddenly contracts plague, how can it be distinguished? It is distinguished by sudden onset of body heat. Since both Shanghan (Cold Damage) and plague present with body heat, one must carefully inquire of the wet nurse whether the child suddenly undressed, bathed in water, or slept facing the wind. Only if there is indeed no common cold can one look towards plague as the diagnosis. One must also verify the presence of red eyes, red stool, dry tongue with yellow or black coating, tidal fever at dusk (ri bu chao re), delirium, yellowish macules, or constipation, or dysentery-like diarrhea with bloody mucus. Only then can it be diagnosed as plague. Mistakenly identifying miscellaneous diseases as plague is an error. Wu Youke specifically criticized ordinary physicians for mistakenly identifying pediatric plague as miscellaneous diseases; this view only sees one side of the issue. In summary, distinguishing pediatric plague is extremely difficult.

Taoye Yu Fa (Peach Leaf Bath Method): Use 3-4 liang of peach leaves, decoct in water, and pour over the body 5-6 times daily. Then, take two pieces of Xiong Shushi (Stercor Muscerdomestici Fermentatus, male rat feces), lightly roast, grind, and take with water.

Erxiang San (Two Fragrances Powder): (For Tianxing Zhuang Re, i.e., epidemic high fever.)
Muxiang (Aucklandiae Radix, powdered, 3 fen), Tanxiang (Santalum Album Lignum, powdered, 3 fen).
Mix with clear water for oral administration. (Still apply with warm water to the fontanelle.)
