Fuling (Poria, 4 liang; some editions state 6 liang) Renshen (Ginseng Radix et Rhizoma, 1 liang) Fuzi (Aconiti Lateralis Radix Praeparata, 1 piece, used raw, broken into eight pieces) Gancao (Licorice Root, 2 liang, honey-fried) Ganjiang (Zingiberis Rhizoma, 1.5 liang) The above
five herbs are boiled in five sheng of water to obtain three sheng of decoction. The dregs are removed, and the liquid is taken warm, seven ge per dose, three times a day.
After sweating or purging therapies, if the disease remains unresolved and irritability (fan zao) occurs, this is irritability caused by yang qi failing to secure, known as "yin irritability." However, other symptoms must be considered to avoid misdiagnosing it as Zhizi Chi Tang syndrome. It should be treated with Fuling Sini Decoction. *Bencao* states: Fuling treats rebellious qi, irritability, and fullness.
Gancao (honey-fried) Zhishi (Immature Bitter Orange Fruit, broken, soaked in water, then honey-fried dry) Chaihu (Bupleuri Radix) Shaoyao (Paeoniae Radix Alba)
The above four herbs, each in ten parts, are crushed, sifted, mixed with rice water, and administered as one fangcun bi of powder per dose, three times a day. If coughing occurs, add Wuweizi (Schisandrae Fructus) and Ganjiang (Zingiberis Rhizoma), each five parts; this also treats diarrhea. If palpitations occur, add Guizhi (Cinnamomi Ramulus), five parts. If urination is difficult, add Fuling (Poria), five parts. If abdominal pain occurs, add one Fuzi (Aconiti Lateralis Radix Praeparata), processed until cracked. If diarrhea is accompanied by a sensation of heaviness in the rectum, first boil Xiebai (Allii Macrostemonis Bulbus) in five sheng of water to obtain three sheng, remove the dregs, add three fangcun bi of the powder to the liquid, boil to obtain one and a half sheng, and divide into two warm doses. *Bielu* states: Xiebai primarily warms the middle and dissipates nodulation.
Shaoyin disease presenting with cold extremities (sini), where the patient may have coughing; or palpitations; or difficult urination; or abdominal pain; or diarrhea with rectal heaviness. This is heat pathogen transmitted from the shaoyin channel, without yin symptoms such as faint pulse or aversion to cold. Even regarding diarrhea, it is not undigested food, but rather rectal heaviness, so warming herbs should not be used. It should be treated with Sini San to disperse pathogenic factors and unblock qi. Although named "Sini," it differs significantly from previous methods. All accompanying symptoms are addressed through modifications.
Highly effective for treating diarrhea.
Danggui (Angelicae Sinensis Radix) Guizhi (Cinnamomi Ramulus) Shaoyao (Paeoniae Radix Alba) Xixin (Asari Radix et Rhizoma) (each 3 liang) Gancao (Licorice Root) Tongcao (Tetrapanacis Medulla) (each 2 liang) Dazao (Jujubae Fructus) (25 pieces) The above
seven herbs are boiled in eight sheng of water to obtain three sheng. Take one sheng warm per dose, three times a day.
Danggui (Angelicae Sinensis Radix, 3 liang) Gancao (Licorice Root) Tongcao (Tetrapanacis Medulla) (each 2 liang) Shaoyao (Paeoniae Radix Alba) Guizhi (Cinnamomi Ramulus) Xixin (Asari Radix et Rhizoma) (each 3 liang) Dazao (Jujubae Fructus) (25 pieces) Wuzhuyu (Evodiae Fructus, 2 sheng) Shengjiang (Zingiberis Rhizoma Recens, half jin) The above
nine herbs are boiled together with six sheng of water and six sheng of clear wine to obtain five sheng. Remove the dregs and divide into five warm doses.
Cold hands and feet with a fine pulse nearly imperceptible should be treated with Danggui Sini Decoction. This sini is due to pathogen transmitted from the taiyang channel, while exterior symptoms remain unresolved. Because yang qi is deficient, Guizhi Tang (Cinnamon Twig Decoction) is used with Danggui (Angelicae Sinensis Radix) to harmonize blood; Xixin (Asari Radix et Rhizoma) warms and disperses to harmonize interior and exterior yang. If the person has chronic internal cold, Danggui Sini Decoction plus Wuzhuyu and Shengjiang should be used. "Chronic internal cold" refers to the constitution. It must be confirmed through inquiry or other current symptoms. Wuzhuyu (Evodiae Fructus) warms the middle and dispels cold, with a more potent nature.
Note: The previous sini methods all focus on warming. These two formulas combine warming the middle with unblocking yang and harmonizing yin. Diarrhea with a large pulse indicates deficiency. Whenever symptoms indicate deficiency but the pulse is large, it signifies insecure primordial qi, often due to forced purging. One must seek the cause of the deficiency. If the pulse is floating and革 (ge), the *Bian Mai Fa* chapter states: A pulse that is xian (string-like) and da (large). Xian indicates reduction; da indicates khou (hollow). Reduction implies cold; hollow implies deficiency. Cold and deficiency interacting is called ge pulse. If intestinal rumbling occurs, it is due to blocked qi movement. It belongs to the indication for Danggui Sini Decoction.
