[Two Prescriptions]

Prescription for treating Taiyang cold damage (Shanghan) with tight and choppy pulse, aversion to cold, fever, and body ache.
Fuzi (Prepared Aconite Root), Wutou (Aconitum Carmichaelii Root) (each 4 liang), Renshen (Ginseng Radix et Rhizoma), Fuling (Poria), Banxia (Pinelliae Tuber) (each 5 liang), Zhusha (Cinnabar) (1 liang).
Grind the above six herbs into fine powder, mix with honey to make pills, coat with genuine cinnabar for color. Take before meals, two pills the size of a soybean each time, washed down with ginger decoction. Take three times a day. Shortly after taking the medicine, drink about two sheng of hot porridge, cover with blankets until sweating occurs, then stop covering. If no sweat occurs, or if sweat is scanty and the disease persists, administer again as previously directed. If sufficient sweat occurs but the disease does not resolve, Guizhi Tang (Cinnamon Twig Decoction) should be taken. This medicine is highly toxic; for those with heat constitution, instruct them to drink water; for those with cold constitution, use warm liquid to detoxify. For treating malaria, take two pills before the onset of symptoms. (In *Jin Gui Yao Lue*, Xixin is used instead of Renshen.)

For cold damage persisting for five to six days or more without resolution, with heat stagnating in the chest, trismus (lockjaw) preventing speech, and only desiring to drink water, this is termed "Huai Shanghan" (damaged cold damage due to mismanagement). If physicians cannot treat it, death ensues when essence and spirit are exhausted, yet warmth remains only at the epigastrium. Use a stick to pry open the mouth and pour medicine down the throat; if the medicine is swallowed, the patient will recover. Mainu Wan (Wheat Slave Pill), also known as Heiniu Wan (Black Slave Pill) or Shuijie Wan (Water Resolution Pill).
Fudi Mo (Pot Bottom Ink/Soot), Zaotu Mo (Stove Chimney Soot), Liangshang Chen (Dust from Beams), Mainu (Black mildew on wheat spikes), Huangqin (Scutellariae Radix), Dahuang (Rhei Radix et Rhizoma), Mangxiao (Natrii Sulfas) (each 1 liang), Mahuang (Ephedrae Herba) (2 liang).
Grind the above eight herbs into fine powder, mix with honey to make pills the size of a bullet. Take one pill, crush it in 5 ge of fresh well-water, let it dissolve completely, and drink the solution. When the patient desires water, allow them to drink freely without limiting the quantity; even if they wish to stop, force them to drink. More drinking is better. If they do not desire water, force-feed them. Shortly after taking the medicine, the patient will feel cold. After the cold sensation passes...

[One Case Record, Two Prescriptions]
The case record states: The general principle is that spring is suitable for using emetic therapy. Whenever administering emetics, stop once the desired effect is achieved; there is no need to consume the entire dose.
If the symptoms resemble Guizhi Tang syndrome (characterized by fever, wind aversion, and sweating) but without headache or neck stiffness, while the Cun-kou pulse is floating, the chest feels hard and full, and qi rushes upward to the throat causing dyspnea, this is due to chronic cold pathogens in the upper chest. There is stifling pain in the chest, inability to eat, a desire for someone to press the area, excessive salivation, and diarrhea occurring more than ten times a day, with the patient's pulse indicating Shaoyin disease (Lesser Yin disease).
In Shaoyin disease, food is vomited immediately upon entering the mouth, accompanied by a feeling of oppression and nausea in the heart region without actual vomiting. Emetic therapy is appropriate. Retained food in the upper jiao (upper burner/stomach) requires emetic therapy.
If the limbs are cold and the pulse is intermittently knotted (slow with irregular pauses), this indicates pathogenic qi lodged in the chest. There is fullness and irritability in the epigastrium, hunger but inability to eat. Since the pathology is located in the chest, emetic therapy is appropriate.
