Treating rheumatism where wind and dampness mutually contend, with pathogenic factors lodging in the skin, causing joint pain, heaviness and pain below the waist, floating pulse, spontaneous sweating, and aversion to wind.
Paeleiae Radix (Fangji) (washed with wine), Astragali Radix (Huangqi) (each 1.5 qian), Atractylodis Macrocephalae Rhizoma (Baizhu) (1 qian), Glycyrrhizae Radix et Rhizoma (Gancao) (roasted, 8 fen), Zingiberis Rhizoma (Shengjiang) (4 slices), Jujubae Fructus (Dazao) (2 pieces, split).
The above six herbs are decocted in water and taken hot. After taking the medicine, one should feel as if insects are crawling within the skin, and the area below the waist will feel cold like ice. Subsequently, sit on a quilt, wrap another quilt around the lower waist, and induce a slight sweat for recovery.
If there is wheezing, add Ephedrae Herba (Mahuang); if stomach qi is disharmonious, add Paeoniae Radix Alba (Baishao); if qi rushes upward, add Cinnamomi Ramulus (Guizhi); if there is accumulated cold qi below, add Asari Radix (Xixin). (Accumulated cold qi refers to long-standing cold pathogens.)
Fangji Fuling Decoction (from *Jin Gui Yao Lue*) treats edema of the skin type (Pi Shui) with swelling of the four limbs and slight twitching of the skin.
This formula is derived from Fangji Huangqi Tang by removing Atractylodis Macrocephalae Rhizoma (Baizhu), Zingiberis Rhizoma (Shengjiang), and Jujubae Fructus (Dazao). In this formula, Paeleiae Radix (Fangji) and Astragali Radix (Huangqi) are each 3 qian, Glycyrrhizae Radix et Rhizoma (Gancao) is 1 qian, added with Cinnamomi Cortex (Rougui) 3 qian and Poria (Fuling) 6 qian.
Decoct in water and take warm in three divided doses.
Qianjin Fangji Tang treats interarticular rheumatism (Lijie) with pain in the four limbs like needle pricks.
This formula is derived from Fangji Huangqi Tang by removing Astragali Radix (Huangqi) and Jujubae Fructus (Dazao). In this formula, Paeleiae Radix (Fangji), Atractylodis Macrocephalae Rhizoma (Baizhu), and Zingiberis Rhizoma (Shengjiang) are each 4 qian, Glycyrrhizae Radix et Rhizoma (Gancao) is 3 qian, added with Cinnamomi Cortex (Guixin) and Poria (Fuling) each 4 qian, and Aconiti Lateralis Radix Preparata (Wutou) 1 piece (peeled and roasted). Decoct with vinegar and water. Take three times during the day and once at night. One should feel a burning heat, and the bi-syndrome will suddenly alleviate; do not be surprised. If no sensation is felt, take again until sensation occurs, then stop.
Treating cases where disease persists after sweating or purging, with deficient pathogenic factors lingering above the diaphragm, causing epigastric knotting and pain, mental restlessness and vexation (Ao Nu), inability to sleep, tossing and turning, and restlessness in sitting or lying down.
Gardeniae Fructus (Zhizi) (14 pieces, split), Fermented Soybean (Xiangchi) (4 he).
The above two herbs are decocted in water and divided into two doses. Take the first dose warm. If rapid vomiting occurs, discontinue subsequent doses. According to Zhang Zhongjing's examples in the Taiyang chapter, Zhizi Chi Tang is used in three scenarios, all primarily treating conditions where deficient pathogens remain unresolved after sweating or purging. The Gardeniae Fructus (Zhizi) must be plump and raw. Vomiting disperses both the pathogen and fire from above the diaphragm. If it is an epidemic disease with headache and fever, adding Allii Fistulosi Bulbus (Congbai) to this decoction is most effective. Many people do not vomit after taking it because their Stomach Qi is strong. Adding vinegar juice can help, or one may use a goose feather to induce vomiting, or borrow this method to clear stagnant fire above the diaphragm without necessarily inducing vomiting. Alternatively, stir-fried black Gardeniae Fructus (Zhizi) should be used so that the action curves downward to exit via urination. For individuals with inherently weak Wei Qi who catch external pathogens and have excessive spontaneous sweating, the Fermented Soybean (Xiangchi) in this formula must be stir-fried thoroughly. Regarding shortness of breath (Shao Qi), it indicates deficiency of Stomach Qi, so add Glycyrrhizae Radix et Rhizoma (Gancao) to harmonize gently. Vomiting indicates rebellion of phlegm-fluids, so add Zingiberis Rhizoma (Shengjiang) to resolve them. After purging, if there is vexation and abdominal fullness, it clearly indicates turbid qi sinking inward; thus, remove the exterior-releasing Fermented Soybean (Xiangchi) from the base formula and add Aurantii Fructus Immaturus (Zhishi) and Magnoliae Officinalis Cortex (Houpo) to purge downward. After severe purging with pill medicines, if body heat persists and there is slight vexation, it clearly indicates deficient fire disturbing externally; thus, do not use Fermented Soybean (Xiangchi) in the base formula, but add Zingiberis Rhizoma Siccatum (Ganjiang) to warm and harmonize. If there is jaundice with fever, it clearly indicates dampness stagnating and transforming; thus, remove Fermented Soybean (Xiangchi) from the base formula and add Phellodendri Cortex (Bopu) to dry with bitter properties. After purging, if relapse occurs due to labor or diet, it indicates righteous qi failing to overcome pathogens; thus, add Aurantii Fructus Immaturus (Zhishi) to clear the interior, using Qing Jiang Shui (fermented grain water) for decoction to utilize its slight sour taste, guiding the action downward rather than allowing it to rise upward. If there is retained food, add Rheii Radix et Rhizoma (Dahuang) in pieces the size of chess pieces, five or six pieces. These are all variations of the Zhizi Chi Tang method; its efficacy is miraculous and unfathomable, beyond the comprehension of mediocre practitioners.
Zhizi Gancao Chi Tang (from *Yu Han Jing*) treats shortness of breath after purging.

Zhizi Shengjiang Chi Tang (from *Yu Han Jing*) treats vomiting after purging.

Zhizi Houpo Tang (from *Yu Han Jing*) treats vexation and abdominal fullness after purging.
Zhizi Chi Tang minus Fermented Soybean (Chi), plus Aurantii Fructus Immaturus (Zhishi) and Magnoliae Officinalis Cortex (Houpo).
Zhizi Ganjiang Tang (from *Yu Han Jing*) treats persistent body heat and slight vexation after severe purging with pill medicines.
Zhizi Chi Tang minus Fermented Soybean (Chi), plus Zingiberis Rhizoma Siccatum (Ganjiang). The administration methods for the above four formulas are the same as for Zhizi Chi Tang.
Zhizi Bopi Tang (from *Yu Han Jing*) treats Taiyang syndrome presenting with jaundice and fever.
Zhizi Chi Tang minus Fermented Soybean (Chi), plus Phellodendri Cortex (Bopu) and Glycyrrhizae Radix et Rhizoma (Gancao). Decoct in water and take warm in two divided doses.
Zhishi Zhizi Chi Tang (from *Yu Han Jing*) treats relapse due to labor or diet.
Double the amount of Fermented Soybean (Xiangchi) in Zhizi Chi Tang, add three pieces of Aurantii Fructus Immaturus (Zhishi). Use seven sheng of Qing Jiang Shui (fermented grain water), boil empty until four sheng remain, add Aurantii Fructus Immaturus (Zhishi) and Gardeniae Fructus (Zhizi), boil until three sheng remain. Add Fermented Soybean (Chi), boil for five or six boils, strain, and take warm in two divided doses. Cover to induce a slight sweat. If there is food retention, add Rheii Radix et Rhizoma (Dahuang) in pieces the size of chess pieces, five or six pieces.
Zhizi Dahuang Tang treats alcohol jaundice (Jiu Dan) with mental restlessness (Ao Nu) or painful heat in the heart region.
Zhizi Chi Tang plus Aurantii Fructus Immaturus (Zhishi) and Rheii Radix et Rhizoma (Dahuang).
Huangqin Qingfei Yin treats thirst with difficulty in urination.
Zhizi Chi Tang minus Fermented Soybean (Chi), using stir-fried black Gardeniae Fructus (Zhizi) in equal parts with Scutellariae Radix (Huangqin). Take hot to induce vomiting. If ineffective, add a pinch of Fermented Soybean (Xiangchi). The妙用 (profound utility) of this formula lies entirely in inducing vomiting to lift the upper jiao, thereby clearing Lung Qi immediately. If taken without vomiting, not only does the condition prolong and fail to respond, but even if slightly improved, the bitter-cold nature remains trapped inside, severely damaging the vital Qi. Should one not consider this precaution?
Zhizi Ren Tang treats urinary obstruction with vexation, abdominal distension, and fullness.
Zhizi Chi Tang minus Fermented Soybean (Chi), plus Glycyrrhizae Radix et Rhizoma (Gancao), Imperatae Rhizoma (Maogen), and Abelmoschi Semen (Kuizi).
