Zhi Shi (Fructus Aurantii Immaturus, three pieces, prepared by stir-frying with bran, bitter and cold) Zhi Zi (Fructus Gardeniae, fourteen pieces, broken open, bitter and cold) Chi Xiao Dou (Semen Sojae Preparatum, one sheng, wrapped in silk cloth, bitter and cold)
The above three herbs. Use seven sheng of clear fermented grain water. Boil empty first until reduced to four sheng. Add Zhi Shi and Zhi Zi. Boil until two sheng remain. Add Chi Xiao Dou. Boil for five or six more boils. Strain. Take warm, divided into two doses. After taking the medicine, cover with blankets to induce a slight perspiration.
Zhi Shi Zhi Zi Chi Tang (Bitter Orange, Gardenia, and Fermented Soybean Decoction) should theoretically be an emetic agent. Here it states that covering with blankets induces slight perspiration because the heat is concentrated in the upper jiao. Bitter substances induce vomiting; when heat scatters to the exterior, bitter substances disperse it. The *Nei Jing* (Inner Canon) says: "When fire excess prevails, use bitter substances to disperse it." This refers to this principle.
Wang Yutai said: The pathogen of Shanghan (Cold Damage) enters from the exterior, while the pathogen of Laofu (relapse due to overexertion after recovery) arises from within. Diaphoresis (sweating), emesis, and purgation therapies should be applied according to suitability.
After recovery from Shanghan, if fever recurs, Xiao Chai Hu Tang (Minor Bupleurum Decoction) is the primary treatment. If the pulse is floating, resolve it via diaphoresis. If the pulse is deep and solid, resolve it via purgation.
If residual heat remains after recovery and fever recurs, administer Xiao Chai Hu Tang to harmonize Shaoyang (Lesser Yang). A floating pulse indicates heat in the exterior; thus, resolve via diaphoresis.
A deep pulse indicates heat in the interior; thus, resolve via purgation.
After recovery from a major illness, if there is fluid accumulation below the waist, Mu Li Ze Xie San (Oyster Shell and Alisma Powder) is the primary treatment.
After recovery from a major illness, Spleen and Stomach Qi deficiency fails to control Kidney Water, causing water to overflow into the Lower Jiao, resulting in edema below the waist. The *Jin Gui Yao Lue* (Essential Prescriptions of the Golden Cabinet) states: "Edema below the waist should be treated by promoting urination." Administer Mu Li Ze Xie San to promote urination and dissipate fluid retention.
Mu Li (Concha Ostreae, salty and neutral, calcined) Ze Xie (Rhizoma Alismatis, salty and cold) Gua Lou Gen (Radix Trichosanthis, bitter and cold) Shu Qi (Herba Perillae, pungent and neutral, washed to remove fishy odor) Ting Li Zi (Semen Lepidii seu Descurainiae, bitter and cold, calcined) Shang Lu Gen (Radix Phytolaccae, calcined, pungent, sour, salty, and neutral) Hai Zao (Thallus Laminariae seu Eckloniae, salty and cold, washed to remove saltiness. All ingredients in equal proportions)
The above seven herbs. Crush each separately and sieve into powder. Then place in a mortar and grind thoroughly. Mix with rice water and take one Fang Cun Bi (one cubic inch measure) per dose. Stop subsequent doses if urination becomes smooth. Take three times daily.
Salty flavors have the effect of inducing vomiting and purging. The salinity of Mu Li, Ze Xie, and Hai Zai excretes fluid retention. The *Nei Jing* states: "When dampness abounds internally, treat with bitter flavor to level it, assisted by pungent and sour flavors. Use bitter flavor to drain it." The pungent, sour, and bitter properties of Shu Qi, Ting Li Zi, Gua Lou, and Shang Lu guide the resolution of edema and dampness.
After recovery from a major illness, if there is excessive salivation that persists indefinitely, it is due to Cold in the Stomach. Pill medication should be used to warm it. Li Zhong Wan (Regulate the Middle Pill) is suitable.
After sweating, Yang Qi is insufficient, leading to Deficient Cold in the Stomach, which fails to transform fluids, causing excessive salivation and indefinite persistence. Administer Li Zhong Wan to warm the Stomach.
After resolution of Shanghan, if there is emaciation, shortness of breath, and rebellious Qi with nausea, Zhu Ye Shi Gao Tang (Bamboo Leaf and Gypsum Decoction) is the primary treatment.
After resolution of Shanghan, insufficient Jin Ye (Body Fluids) leads to emaciation, and residual heat remains. Heat injures Qi, causing shortness of breath. Rebellious Qi causes nausea. Administer Zhu Ye Shi Gao Tang to regulate Stomach Qi and dissipate heat.
