For severe food stagnation presenting with a distended, full, and oppressive chest where emetic therapy is ineffective, this formula must be used to purge. If the patient experiences coma, fainting, unresponsiveness, and limb stiffness, use Rhubarb (prepared with wine), Croton Seed (shelled and oil removed), and Dried Ginger (each 1 qian). Grind into fine powder, mix with ginger juice to form pills the size of soybeans. Take 5–7 pills each time, dissolved in ginger soup. If diarrhea persists after administration, drink cold rice gruel to stop it.

This formula treats consumptive diseases with bone-steaming fever, Zhu-wu heart pain, cholera with vomiting and diarrhea, seasonal epidemics and malevolent influences, miasmic malaria and plague, amenorrhea due to blood stasis, accumulation masses and carbuncles, convulsions, epilepsy, stroke, phlegm-syncope due to qi obstruction, and various conditions such as coma.
Take Atractylodis Macrocephalae Rhizoma, Aquilariae Lignum Resinatum (Qingmuxiang), Rhinocerotis Cornu (Xijiao), Cyperi Rhizoma (stir-fried and hairs removed), Cinnabar (water-triturated), Terminalia Chebula Retz. Fruit (roasted, peel taken), Santalum Album Lignum (Tanxiang), Styrax Resina (Anshixiang) boiled into paste with wine, Aquilae Lignum Resinatum (Chenxiang), Moschus (Shexiang), Syzygium aromaticum Flos (Dingxiang), Piperis Longi Fructus (Bibo) (each 2 liang), Borneolum Syntheticum (Longnao), Olibanum (Xunluxiang), and Liquidambaris Resina (Suhexiang) (each 2 liang).
Grind all ingredients into a fine powder and mix evenly. Use the Styrax paste and Liquidambar resin, combined with refined honey, to form pills the size of a marble. Seal with wax, place in a crimson silk pouch, and wear against the heart; all evil influences will dare not approach.

Ancient texts state that contracting heat while at rest is called "Zhong Shu" (heatstroke from stillness), while contracting it during activity is called "Zhong Re" (heat illness from motion); Shu is yin and Re is yang. However, considering the character "Shu" (暑) begins with "Sun" (日), it essentially describes the invasion of heat qi. In summer, the scorching sun represents the hyperactive qi of the Taiyang; when humans are exposed to it, Shu disease arises. As for cases contracted while at rest, these result from seeking coolness in deep halls or water pavilions, using large fans, and consuming excessive fruits and melons, leading to cold pathogens. Symptoms may include headache, body ache, fever, and aversion to cold, indicating an external contraction of cold; or vomiting, abdominal pain, and cold limbs, indicating direct invasion of cold into the interior. How does this relate to Shu syndrome? Generally, the differentiation of Shu syndrome relies on specific signs: spontaneous sweating, thirst, vexation, dark urine, body heat, and a deficient pulse. There are distinctions among Shang Shu (injured by heat), Zhong Shu (struck by heat), and Shu Bi (blocked heat). Shang Shu indicates mild exposure, with symptoms of vexation, heat, and thirst, treated primarily with Yiyuan San. Zhong Shu indicates severe exposure, with symptoms of profuse sweating, stupor, unresponsiveness, vexation, panting, and delirious speech. During stupor, administer Xiaoshu Wan to induce immediate awakening. Once awake, clear the heat according to its severity: use Yiyuan San for mild cases and Baihu Tang for severe ones.
Shu Bi refers to internal retention of heat qi blocked externally by wind-cold. Headache, body ache, fever, and aversion to cold indicate wind-cold; thirst and vexation indicate internal heat. Treat with Siwei Xiangru Yin plus Schizonepetae Herba and Gentianae Macrophyllae Radix. Additionally, dampness contracted in summer can cause vomiting and diarrhea, manifesting as cholera, resulting from retained food and fluid. This should be treated by distinguishing cold and heat. For heat patterns, characterized by thirst, use Huanglian Xiangru Yin. For cold patterns, characterized by absence of thirst, use Huoxiang Zhengqi San. Furthermore, there is Gan Huoluan (dry cholera), where the patient desires to vomit but cannot, and desires to defecate but cannot, accompanied by severe intestinal cramping and rapid changes. Ancient formulas recommend inducing vomiting with salt mixed with yin-yang water, or decocting with Chenpi (Citri Reticulatae Pericarpium), or preferably decocting aged Citrus medica L. fruit (Xiangyuan). Commonly known as Jiaochang Sha or Wusha Zhang, this condition arises from turbid qi blocking the meridians, causing qi stagnation and blood coagulation, leading to spleen earth congestion and failure of transport and transformation. This disrupts the normal operation of heaven and earth, resulting in distension, blockage, and critical danger. Therefore, treatment must be swift. Strictly avoid drinking gruel or eating any food, as ingestion will worsen the condition immediately. Exercise utmost caution.
